FireProtect 2 (Heat) Jeweller is a wireless fire detector with a built-in siren. Designed for indoor installation. Detects temperature increase. The detector can operate without a hub.

Available in two modifications: with non-replaceable batteries (with SB in the name) that last 10 years, and with replaceable batteries (with RB in the name) that last up to 7 years.

The detector operates as part of the Ajax system, communicating with the hub via the secure Jeweller radio protocol. Communication range with the hub in the absence of obstacles is up to 1700 meters.

The detector is equipped with a siren (piezoelectric buzzer) for audible notification of alarms and events with a volume of up to 85 dB (at a distance of 3 meters from the detector). The detector is always active, so it responds to fire 24/7, regardless of the system's armed mode.

FireProtect 2 is protected by a tamper. It monitors the removal of the detector from the SmartBracket mounting panel: the detector responds with LED indication and sends notifications to users in Ajax apps and to the security company's monitoring station.

Ajax automation devices can react to a FireProtect 2 alarm and perform user-defined actions using automation scenarios. For example, a WallSwitch relay can turn on the ventilation system and emergency lighting upon an alarm.

Heat Sensor
Two built-in A1 class thermistors are responsible for detecting a sharp increase and exceeding the temperature threshold in FireProtect 2. Thermistors of this class signal an alarm if a rapid temperature increase or a static temperature within the range of +54°C to +65°C is detected.

FireProtect 2 will report an exceedance of the permissible temperature threshold as soon as its value exceeds +64°C. The detector will report a sharp temperature increase if the indicator increases by 10°C within one minute. If the temperature indicator sharply increases by 20°C or more, the detector immediately signals.

Test/Mute Button
To activate the Test/Mute button, lightly press the center of the front panel with your hand or an appropriate object (e.g., a mop handle) if the detector is located in a hard-to-reach place. Test/Mute is a mechanical button under the detector's front panel.

The button performs several functions:

In normal mode - starts a detector performance test.
In case of an alarm - mutes the detector's alarm or the synchronized alarm of all fire detectors in the system for 10 minutes.
In case of a malfunction or low battery level - mutes the audible and LED indication for 12 hours.
Synchronized Fire Detector Alarm
All FireProtect 2 fire detectors support the synchronized alarm function. The function activates the built-in sirens of all fire detectors in the system as soon as one of the fire detectors registers an alarm. FireProtect 2 detector sirens are activated within 20 seconds after alarm detection. FireProtect and FireProtect Plus are activated within the hub-detector polling interval set in the Jeweller (or Jeweller/Fibra) settings, but no later than 60 seconds.

FireProtect 2 detectors have different audible and LED indications for alarm types to make it easier for users to distinguish them. Therefore, in the event of a synchronized alarm, FireProtect 2 detectors reproduce the exact type of alarm that was registered by the initiating detector. The initiating detector additionally signals the alarm with LED indication. FireProtect and FireProtect Plus detectors signal all alarm types with the same sound.

The Ajax system can transmit alarms and events to the PRO Desktop monitoring application, as well as to the central monitoring station (CMS) in SurGard (Contact ID), SIA DC-09 (ADM-CID), ADEMCO 685, and other protocol formats.
