PRODUCT DETAILS

The Ajax FireProtect 2 RB is a wireless smoke and heat sensor that is designed for instant fire detection. The unique smoke chamber does not require regular cleaning and is impenetrable to insects, and the dual-spectrum sensor distinguishes smoke from steam, making it ideal for use in kitchens or open plan properties. 

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.

These RB models feature replaceable batteries which can provide up to 7 years life.

As part of the wireless Jeweller range, the FireProtect 2 RB can be used as a stand-alone product, or added to an existing Ajax alarm hub in order to receive real time notification on the Jeweller app. 


Features:

  • HazeFlow 2 software algorithm to prevent false alarms on the smoke
  • Bispectral optical sensor for filtering false alarms on the smoke
  • Maintenance-free smoke chamber
  • An interconnected alarm of all fire detectors at the facility in 20 seconds
  • Built-in siren with a volume of 85 dB at a distance of 30 meters
  • Ability to operate autonomously without an Ajax hub
  • Up to 10 years on non-replaceable batteries, and up to 7 years on replaceable
  • SmartBracket mounting panel with the ability to align the detector after installation
  • Remote control and configuring via Ajax apps
  • Pairing with the Ajax hub via QR code

Patented smoke chamber
Protects the smoke sensor from dust, dirt, and insects.
Dangerous temperature detection
Sensitive element
according to the requirements for Class A1 temperature detectors

Requirements of EN 54-5 and BS 5446-2 standards.
High temperature alarm
at temperatures above 64°C
Temperature spike alarm
when the temperature rises more than 10°C in 1 minute or less
Additional features
In-built siren
volume 85 dB at a distance of 3 meters

Sound notification of alarms. Active until the reason for triggering is eliminated or until the user disables notification.
Interconnected Fire Detectors Alarms
All fire detectors in the system turn on built-in sirens if at least one of the detectors registers an alarm. An interconnected fire alarm is activated during one “hub — detector” polling interval but no more than 20 seconds later.
LED indication
green is a power indication

A LED indicator on the device enclosure lights up once every 56 seconds. The indication meets the requirements of EN 50291.
yellow is an indication of malfunctions

A LED indicator on the device enclosure lights up when malfunctions are detected. For example, in the case of discharged batteries, contamination of the smoke chamber, or end of the service life.
red is an indication of fire alarms

A LED indicator on the device enclosure lights up when the detector registers a fire alarm.
Button on the front panel of the detector
In normal mode, when pressed, it starts the smoke chamber test. In the event of an alarm or malfunction, the pressing turns off the detector sound notification.
Recommendations
The device is designed only for indoor installation.
SmartBracket mounting panel allows adjusting the position of the detector after installation.
Anti-sabotage protection
Tampering alarm
Alerts of attempts to detach the detector from the surface or remove the mounting panel.
Protection against spoofing
device authentication
Detection of communication failure
within 15 minutes

The time to detect communication loss depends on the settings for the number of undelivered data packages (specified in the Jeweller or Jeweller/Fibra settings). The polling interval is fixed at 300 seconds
