AJAX FireProtect 2 wireless Heat Detector

Featured with a built-in siren for alarm and event notification. It can operate as part of the Ajax security system and autonomously without a hub.

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.

Product Questions

After how many years do I have to replace an old fire detector with a new one?
Question by: Wolfgang on Jun 7, 2025, 1:22 PM
A fire detector (smoke / heat detector) should generally be replaced every 10 years. This is the standard service life of most smoke detectors, including those from Jablotron, Notifier and DSC.

Why replace after 10 years?
> Sensor ageing: The smoke detector loses its sensitivity over time.
> Battery wear: Even models with long-life batteries can run out after 10 years.
> Reliability: After 10 years, the risk of faults increases and security systems must always be reliable.

Hello, can Ajax fire detector be used as a siren in case of break-in? That would make it useful compared to other connected fire detectors, as it would create loud noise in case of break-in. Or do I need to have internal sirens even if I also have AJAX fire detectors?
Question by: Konstantin on Jun 13, 2024, 12:12 AM
Unfortunately, this is not possible with the Ajax system, the siren only goes off in the event of a fire alarm. With Jablotron this is possible.
