Operating principle
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 by more than 10°C within a minute, the detector recognizes this as a rapid temperature rise and raises the alarm.
Detection of dangerous CO concentration level
A built-in chemical sensor with a service life of at least 10 years is
responsible for detecting a dangerous concentration of carbon monoxide in
FireProtect 2.
Carbon monoxide (CO) is a colourless, tasteless, and odourless gas produced
due to incomplete fuel combustion in automobile engines and heating appliances
that use coal or other natural fuels. For example, it can be made by
fireplaces, boilers, or heating systems. In airtight or closed rooms with poor
ventilation, life-threatening concentrations of carbon monoxide can
accumulate.
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 detectors operate with the hub.
Operation without a hub
FireProtect 2 detectors can be used without pairing to an Ajax hub. In this
case, the detector notifies about fire alarms with a built-in siren and LED
indication, and 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 can be checked at any time in
Ajax apps.
The detector supports manual testing mode. It is activated by pressing the
devices 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
FireProtect 2 (Heat/C0) is available in two versions: with replaceable or
sealed batteries. Detectors with replaceable batteries operate for up to 7
years with pre-installed CR123A batteries. After discharge, the batteries can
be replaced with new ones. The model with sealed lithium batteries operates
for at least 10 years. After the batteries are discharged, the detector should
be replaced with a new one. 
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 1,700 meters. This communication
range allows you to install detectors even on large-scale objects.
Jeweller is responsible for transmitting alarms and events. The radio protocol
also provides an interconnected fire detectors alarm activation within 20
seconds in a system with any number of FireProtect 2. Thanks to Jeweller,
users and the monitoring station can always see the current status of
detectors in Ajax apps.
Quick pairing and installation
There is no need to disassemble the detector during installation. With an improved SmartBracket panel, an installer can effortlessly fix the detector on ceilings and level it at 90° angles after mounting. The Ajax apps help quickly make the device a part of the system. And it can always be reconfigured remotely without site visits.
