How to replace FireProtect 2 RB (CO) batteries

The detector is equipped with a siren (piezoelectric buzzer) for audible notication of alarms and events with a volume of up to 85 dB (at a distance of 3 m from the detector). The detector is always active and reacts to a re 24/7, regardless of the system’s security mode.

FireProtect 2 is protected by tamper. The tamper controls the removal of the detector from the SmartBracket mounting panel: the detector reacts with LED indication and sends notifications to users in Ajax apps and the CMS.
Ajax automation devices respond to FireProtect 2 alarms and perform user- defined actions using automation scenarios. For example, the WallSwitch relay can turn off the ventilation system and turn on emergency lighting when an alarm occurs.
CO (carbon monoxide) sensor
FireProtect 2 has a chemical sensor which detects dangerous levels of carbon monoxide. The operation principle of the sensor is based on a chemical reaction. There is an electrolyte bath inside the sensor. When a specific level of carbon monoxide is reached, a chemical reaction is triggered. The detector reads this event and transforms it into an alarm.
The detector raises an alarm if the CO level reaches:

• 50 ppm (0.005%) and above — in no more than 90 minutes.
• 100 ppm (0.01%) and above — in no more than 40 minutes.
• 300 ppm (0.03%) and above — in no more than 3 minutes.

A CO concentration of 400 ppm (0.04%) for three hours is life-threatening. The detector stops warning of a dangerous carbon monoxide level as soon as the concentration drops to 40 ppm (0.004%).

Test/Mute button
Тo activate the Test/Mute button, press lightly on the centre of the front panel with your hand. Use a suitable item (mop handle) if you can’t reach up the detector with your hand. Test/Mute is a mechanical button placed under the front panel of the detector.

The button performs several functions:

• In normal mode, it starts the detector self-test.
• In case of an alarm, it mutes the detector alarm or Interconnected Alarm of all re detectors in the system for 10 minutes.
• In case of a fault, low battery level, or end of life, it mutes the sound and LED indication for 12 hours.

Use any remote silencing feature only in the line of sight of the CO sensor.

Interconnected Fire Detectors Alarms*

All fire detectors of the FireProtect 2 product line support the Interconnected Alarm feature. This feature activates the built-in sirens of all fire detectors in the system as soon as at least one of the fire detectors detects an alarm. Sirens of FireProtect 2 detectors are activated within 20 seconds after an alarm is detected. FireProtect and FireProtect Plus are activated over a detector ping interval set in the Jeweller or Jeweller/Fibra settings, but no later than in 60 seconds.
The FireProtect 2 detectors have different sound and LED indications of alarm types to make it easier for users to distinguish between them. In case of interconnected alarm, all FireProtect 2 detectors indicate exactly the alarm type detected by the initiating detector. Instead, FireProtect and FireProtect Plus detectors notify all types of alarms with the same sound.

How to set Interconnected Fire Detectors Alarms

How to mute Interconnected Fire Detectors Alarms
*The Interconnected Fire Detectors Alarm function is not certified according to EN 14604 and EN 50291.
Sending events to the CMS
The Ajax system can transmit events and alarms to the PRO Desktop monitoring app as well as the Central Monitoring Station (CMS) via SurGard (Contact ID), SIA DC-09 (ADM- CID), ADEMCO 685, and other protocols. The list of supported protocols is available here.

Which CMSs Ajax connects to

Addressability of Ajax devices allows you to send not only events but also the type of the device, the name, virtual room, and security group assigned to it to the PRO Desktop and to the CMS. The list of transmitted parameters may differ depending on the type of the CMS and the selected communication protocol.
The ID and detector loop (zone) number are available in the detector States.

Adding to the system

Before adding a device

1. Install the Ajax app.
2. Create an account if you don’t have one.
3. Add a hub compatible with the detector to your app. Set the required settings and create at least one virtual room.
4. Make sure that the hub is on and has Internet access via Ethernet, Wi-Fi, and/or mobile network. You can do this in the Ajax app or by looking at the  LED indicator of the hub: it should light up white or green.
5. Make sure that the hub does not start updates and that it is disarmed by checking the status in the Ajax app.

A PRO or a user with system setup rights can connect the device to the hub.

To connect to the hub, the detector should be within the coverage area of the hub radio network. To operate via a radio signal range extender, first connect the detector to the hub and then to the range extender. You can do this in the range extender settings in Ajax apps.

How to connect FireProtect 2 to a hub

1. Open the Ajax app.

2. Select the hub if you have several of them or if you are using the Ajax PRO app.

3. Go tothe Devices tab. Press Add Device.

4. Enter the name of the device.

5. Scan the QR code or enter the ID manually. QR code is located on the rear part of the enclosure (under the mounting panel) and on the device packaging. The device ID can be found below the QR code.

6. Select the virtual room and security group (if the group mode is enabled).

7. Click Add; the countdown will begin.
   If the maximum number of devices is added to the hub, when you add the device, you will get a notication of exceeding the device limit. The number of devices that you can connect to the hub depends on the central unit model.

8. Turn on the detector by holding the power button for 3 seconds. The hub connection request is sent only if the detector is enabled. If the detector fails to connect to the hub, try again in 5 seconds.

The detector cannot connect to the hub if they operate on different radio frequencies. The radio frequency range of the devices may vary by region. Please contact technical support for information on the operating frequency range of your devices.

Once connected, FireProtect 2 will appear in the hub device list in the Ajax app.
Device status update depends on the ping interval set in the Jeweller or Jeweller/Fibra settings. The default value is 36 seconds.

FireProtect 2 only works with one hub. When connected to a new hub, the detector stops transmitting data to the old hub. Once added to a new hub, FireProtect 2 is not removed from the list of devices of the old hub. This must be done manually in the Ajax apps.

Autonomous operation mode

FireProtect 2 detectors can be used autonomously without connecting to an Ajax hub. In this case, the detector notifies of dangerous CO level with only a built-in siren and LED indication. Users don’t receive notifications on any Ajax apps, including Ajax Translator, or PRO Desktop. The Interconnected Fire Detectors Alarms feature is also unavailable for this operation mode.

To use the detector autonomously, follow these steps:

1. Select the optimal location of the detector using the recommendations in the Selection of installation place section.
2. Mount the detector on the SmartBracket panel as described in the Installation section.
3.  Press the power button to switch on the detector.
4.  Start a self-test with the Test/Mute button. Press the centre of the front panel and hold it for 1.5 seconds.

During a self-test FireProtect 2 notifies about each step with a built-in siren and LED indication. Once a self-test is completed, the LED indication turns off, and the detector works autonomously.
In case of an alarm, press the Test/Mute button or eliminate the cause of the alarm to mute the siren.

Battery life optimization setting
The Battery Life Optimization feature is provided to save the detectors’ battery charge. It is available only for hubs on or OS Malevich 2.14 higher with FireProtect 2 detectors connected. This feature is enabled by default.

When the Battery Life Optimization feature is enabled, the hub increases the ping interval for FireProtect 2 detectors.
This feature doesn’t affect alarm notication delivery time.

To disable the Battery Life Optimization feature:

1. Open the Ajax app.

2. Select the hub with FireProtect 2 detectors connected.

3. Go to:
   Hub → Settings → Service → Fire Detectors Settings.

4. Disable the Battery Life Optimization toggle.

5. Click Back to save the settings.

If the Battery Life Optimization feature is disabled:

• FireProtect 2 SB (CO) built-in battery life is 5 years (instead of 10).
• FireProtect 2 RB (CO) pre-installed battery life is 3.5 years (instead of 7).

Selection of installation place

The detector is designed for indoor installation only.

The coverage area of one FireProtect 2 (CO) is 50 to 60 m², depending on the type of premises. The detector should be installed in every room. The detector is suitable for installation in premises where the generation of gases/vapors/smoke is part of the operating process. For example, in a garage, kitchen, or boiler room.
The detector mounts on the wall at a height of 1.5 m from the oor. As an alternative it can be mounted on the ceiling. The detector must be placed at a distance of 30 cm from light xtures, chandeliers, or any other decorative objects that may interfere with alarm detection.
In halls or narrow corridors, detectors should be installed at a distance of no more than 7.5 m from each other.

When installing on the wall, ensure the LEDs are visible to the user. It means FireProtect 2 must be installed upside down.

When choosing the location of the detector, consider the parameters that affect its operation:

• Jeweller signal strength.
• Distance between the detector and the hub.
• Presence of barriers for radio signal passage between devices: walls, interoor ceilings, large objects located in the premises.

Consider the placement recommendations when designing your Ajax system for the object. The security system must be designed and installed by specialists.
The list of recommended partners is available here.

Signal strength
The Jeweller signal strength is determined by the ratio of the number of undelivered/corrupted data packets that are exchanged between the hub and the detector to expected ones within a certain period of time. Signal strength is indicated by the icon on the Devices tab:

• Three bars — excellent signal strength.
• Two bars — good signal strength.
• One bar — low signal strength; stable operation is not guaranteed.
• Crossed out icon — no signal; stable operation is not guaranteed.

Check the Jeweller signal strength at the installation site. If the signal strength is as low as one or zero bars, we cannot guarantee stable operation of the device. In this case, move the device. Repositioning even by 20 cm can signicantly improve the signal reception.
If, after relocation, the detector still has a low or unstable signal strength, use a radio signal range extender.

Do not install the detector

1. Outdoors. This can lead to the detector failure.
2. In places with low or unstable Jeweller signal strength. This can result in the connection loss.
3. Inside premises with temperature and humidity outside the permissible limits. This could damage the detector.
4. In places with fast air circulation. For example, near fans, vents, open windows, or doors. This can lead to false alarms..
5. In the corners of the room. This can lead to false alarms.
6. Near lighting xtures, decorations, and other interior items that may interfere with the circulation of air in the room. This could lead to false alarms.
7. Closer than 1–1.5 meters to an open ame source. For example, near a replace, grill, or kitchen stove. This can lead to false alarms.
8. In high or inconvenient places. Access to the Test/Mute button is required to mute the alarm and test the detector if it’s used without connection to a hub.

Installation

Make sure that you have selected the optimal installation place and it complies with the requirements of this manual.
Only a competent specialist should install this device.

To install the detector:

1. Remove the SmartBracket mounting panel from the detector. To remove the panel, turn it counterclockwise.

2. Fix the SmartBracket mounting panel to a surface using double-sided adhesive tape or other temporary fasteners. The mounting panel has an UP sign, which indicates the correct position.
   Use double-sided adhesive tape for temporary xation only. The device xed by the adhesive tape can peel off the surface at any time, which can lead to damage if the device is dropped.

3.  Run the Jeweller Signal Strength Test. The recommended value is two or three bars.
   Consider to relocate the device as repositioning even by 20 cm can signicantly improve the signal strength. If there is still low or unstable signal after the relocation, use a radio signal range extender.

4. Remove the detector from the mounting panel.

5. Attach the SmartBracket panel with the bundled screws using all xation points. When using other fasteners, make sure they do not damage or deform the mounting panel.

6. Place the detector on the SmartBracket mounting panel.

7. Adjust the position of the detector if necessary.

It is necessary to perform a self-test after the installation is nished.

Actions to take in case of CO alarm

1. Immediately open all the doors and windows to ventilate the premises if it is safe.
   NEVER IGNORE THE ALARM! When you open the doors and windows for ventilation, the CO level can drop to acceptable, and the alarm may have stopped by the time help arrives. The solution to the problem may be temporary. You have to determine the CO source and make a repair.

2. Stop using and turn off all fuel devices where it is possible.

3. Evacuate from the premises leaving the doors and windows open.
   WARNING: If you hear the CO alarm, it has detected dangerous levels of carbon monoxide. Always evacuate from the premises, even if you are unsure about the cause of a CO alarm.

4. If you have a headache and nausea, get medical help immediately. These could be the result of carbon monoxide poisoning, so tell your doctor about it.

5. Call your gas or other fuel supplier’s hotline. Keep the number in a noticeable place.

6. Avoid re-entering the premises until the alarm stops.
   If the alarm was silenced by the Test/Mute button (for CO level under 300 ppm), check the CO level at the Ajax app. If it is safe to enter the premises, press the Test/Mute button again to check the CO level.
   Any remote silencing feature (e.g., via Ajax app) shall only be used in the line of sight of the CO siren.

7. Do not use the fuel or gas appliances again until registered installers or experts have checked them.

Carbon monoxide impact
Carbon monoxide poisoning occurs regularly: many people are killed each year, and many more suffer ill health. CO is an invisible, odorless, tasteless, and extremely toxic gas. CO is produced by burning such fuels as petrol, diesel, coal, oil, natural/bottled gas, paran, wood, charcoal, etc. The heart and brain are rapidly damaged by oxygen starvation because red blood cells in the lungs absorb CO faster than oxygen.

The most common reasons for high levels of CO in premises:

• Engines of cars, generators, etc., are left running in conned spaces (for example, a garage).
• Incorrectly or poorly installed fuel-burning appliances.
• Blocked or damaged vents or chimneys/ues.
• The tightness of rooms where appliances for burning fuel or replaces are installed.
• Bad ventilation in rooms with portable gas/paran heaters.

IMPORTANT: A CO alarm should not be used as a substitute for proper installation, use, and maintenance of fuel-burning appliances, including appropriate ventilation and exhaust systems.

The CO exposure period is also important. A low level for a long period (e.g., 150 ppm for 90 minutes) can cause the same symptoms as a high level of CO for a short period (e.g., 300 ppm CO for 30 minutes). The table below shows how different concentrations of CO affect people.
FireProtect 2 may not prevent the chronic effects of carbon monoxide exposure and will not fully protect people from the high-risk group.

CO
concentration in the air, ppm| Approximate inhalation time and consequences
---|---

35

| The maximum allowable concentration for continuous exposure in any 8-hour period (according to Occupational Safety and Health Association; OSHA).
150| Slight headache after 1.5 hours.
200| Slight headache, fatigue, dizziness, and nausea after 2–3 hours.
400| Frontal headaches within 1–2 hours, life-threatening after 3 hours.
800| Dizziness, nausea, and convulsions within 45 minutes. Unconsciousness within 2 hours. Death within 2–3 hours.
1,600| Headache, dizziness, and nausea within 20 minutes. Death within 1 hour.
3,200| Headache, dizziness, and nausea within 5–10 minutes. Death within 25-30 minutes.
6,400| Headache, dizziness, and nausea within 1–2 minutes. Death within 10–15 minutes.
12,800| Death within 1–3 minutes.

Even if people realize they are not well, they become so disoriented by the carbon monoxide that they cannot call for help or get out of the room to save their lives. Numerous cases of carbon monoxide poisoning show that children and household pets are affected rst.

Malfunctions

If FireProtect 2 malfunction is detected (for example, there is no connection with the hub), the malfunction counter is displayed in the device eld in the Ajax apps.
All malfunctions are displayed in the detector States. Fields with malfunctions are highlighted in red.
The device can report malfunctions to the CMS, as well as to users through push notications and SMS.

FireProtect 2 (CO) malfunctions:

• No connection with the hub or radio signal range extender.
• The detector’s enclosure is open.
• Low battery charge level.
• The device service life has expired.
• Hardware malfunction (failure of the sensor of the detector).

Maintenance

The detector has a self-test system and does not require the user or installer intervention. We recommend running a self-test periodically to familiarize people
with the alarm sound and LED indication.
FireProtect 2 devices connected to the Ajax hubs generally do not require routine testing.
All connected devices are constantly monitored for possible Faults, Low battery, and EOL signals.
However, we encourage all users to test FireProtect 2 devices periodically (monthly) to allow residents of the building to become familiar with the re alarm signals of the system.
Please be aware that your local regulation might require more frequent testing (e.g., weekly).
Clean the detector enclosure of dust, cobwebs, and other contaminants as they emerge. Use a soft dry cloth suitable for equipment care. Do not use substances that contain alcohol, acetone, gasoline, and other active solvents.
The service life of the detector is 10 years. After this period, the sensitivity of the sensors decreases. We recommend replacing the detector with a new one to ensure uninterrupted re protection at the premises.
The version of the detector with replaceable batteries (has RB in the name) operates from pre-installed batteries for up to 7 years. When the batteries are discharged, replace them with new ones.

How to replace batteries in FireProtect 2 RB (CO)

A detector with sealed batteries (has SB in the name) should be replaced with a new one after the batteries are discharged.

Ensure the batteries are installed with the correct polarity. The polarity is marked inside the enclosure. Please run a self-test with Ajax apps or by pressing the Test/Mute button after the batteries are replaced to check the correct operation of the detector.

Cautions

Avoid the situations listed in the tables below. They may affect the reliability of the CO sensor in the short or long term.

Situations that must be avoided

characteristics when the sensor is contaminated by alkaline metals, especially salt water spray.
Exposure to high concentrations of common (non-acidic) gases| Exposure to high concentrations of common gases such as ammonia may cause irreversible changes. Avoid long-term exposure to or use of packing materials that may generate common gases.
Impact of volatile organic compounds (VOCs)| Prolonged off-gassing from such VOCs may cause irreversible changes to:
styrene (commonly used in blister packs and packing trays);
α-pinene (found in some kinds of printing inks).
Avoid packing the FireProtect 2 in a tightly closed container where VOC gases may be present.
Excessive exposure to alcohol or acetone vapors the sensor may cause its temporary disability.
Contact with water| Soaking or splashing the sensor with water may change its characteristics.

Situations to avoid whenever possible

silicone adhesives, hair grooming materials, or silicone rubber/putty.
Dew condensation| The clog of gas diffusion route or deterioration of the sensing membrane. Avoid severe dew condensation that occurs for an extended period inside or on the sensor surface.
Exposure to hydrogen sulde or sulfuric acid gas| Sensor components corrosion, resulting in sensor damage.
Presence of dust and oil mist| Clogging of the sensor’s internal structure caused by extremely high dust or oil mist concentrations.

Additional cautions for installation

The sensor requires oxygen to function properly and have the characteristics described in this manual. The sensor will not operate properly in a zero- oxygen environment.
