Operating principle

Smoke detection

FireProtect 2 detects smoke and does not react to water vapour thanks to a bispectral optical sensor with blue and infrared LEDs. LEDs emit light with different wavelengths, which allows the detector to determine the size of the volatile particles and react only to smoke. The detector’s smoke chamber is protected from dust, dirt, and insects. Even if dust enters and settles in the smoke chamber, it does not threaten or impair the detection. The optical system is desigrned so that non- volatile particles or insects cannot be in two beams simultaneously and cause a false alarm.

Detection of a rapid temperature rise

Two built-in thermistors are responsible for the reaction to temperature rise. Thermistors are located outside the detector for faster threat detection. If the room temperature exceeds 64°C or increases at more than 10°C per minute, the detector recognizes this as a rapid temperature rise and raises the alarm. The temperature alarm can trigger even if there is no smoke in the room.

Interconnected fire detectors alarms
The detector supports interconnected fire alarms. The feature activates built- in sirens of all Ajax fire detectors at the facility if at least one of them is triggered. In case of a fire, this allows alerting as many people as possible. FireProtect 2 detectors have an improved interconnected fire alarm algorithm that activates all fire detectors’ sirens within 20 seconds. The function is available only when the detectors operate with the hub.

Operation without a hub

FireProtect 2 detectors can be used without connecting to an Ajax hub. In this case, the detector notifies fire alarms with a built-in siren and LED indication but does not send a notification to the user’s smartphone, Ajax Translator, or PRO Desktop. FireProtect 2 detectors can be used without connecting to an Ajax hub. In this case, the detector notifies fire alarms with a built-in siren and LED indication but does not send a notification to the user’s smartphone, Ajax Translator, or PRO Desktop.

Manual and automatic testing

FireProtect 2 regularly checks the status of batteries and built-in sensors. If a malfunction is detected, the hub will notify users and the monitoring station instantly. And the detector will turn on the light and sound alert by the built-in siren and LEDs. All detector states Cn be checked at any time in Ajax apps The detector supports manual testing mode. It is activated by pressing the device’s front panel. The front panel has a mechanical button, which can be pressed either manually or with a floor mop. During the test, the built-in siren and testing of sensors are run. This allows the installer to test the device at any time and to demonstrate to the customer the light and sound indication of the detector for various types of alarms.

Autonomous operation

Two models of FireProtect 2 (Heat/ Smoke) are available – with replaceable and non-replaceable batteries. Detectors with replaceable batteries operate for up to 7 years with pre-installed CR123A batteries. After their discharge, the batteries can be replaced with new ones. The model with non-replaceable batteries works from built-in lithium batteries for at least 10 years. After the batteries are discharged, such a detector should be substituted with a new one.

Jeweller communication technology

Jeweller is a radio protocol for fast and reliable two-way communication between hubs and connected devices. The protocol provides a wireless radio communication range with FireProtect 2 up to 1700 meters. This communication range allows you to install detectors even on large-scale objects. The jeweler is responsible for transmitting alarms and events. The radio protocol also provides an interconnected fire detector alarm activation within 20 seconds in a system with any number of FireProtect 2. Thanks to Jewellers, users, and the monitoring station can always see the current status of detectors in Ajax apps.

Quick pairing and installation

To install FireProtect 2, it is not necessary to disassemble the detector enclosure. Replaceable or non-replaceable batteries are pre-installed, and the SmartBracket mount is removed from the detector without tools. SmartBracket mounting panel has a degree of freedom of 90°. This allows the installer to align the position of the device after installation. The detector connects to the Ajax security system in less than a minute. An installer needs to open the Ajax app, scan the QR code, and add the device to the room and security group.
