Home Automation

Ajax

Wireless combined heat, smoke, and CO detector with sealed batteries

Principle of operation
Ajax FireProtect 2 SB (Heat/Smoke/CO) Jeweller is a wireless fire detector that detects smoke, dangerous temperature rise, and carbon monoxide (CO) to warn about fire and hazardous gases.

Features
Features a built-in siren for loud local alerts and supports interlinked alarms with other Ajax fire detectors.

Installation and set up
Ready to use out of the box. The battery is sealed inside, and the detector is mounted in minutes using the mounting bracket.

Communication
Jeweller communication technology Proprietary wireless communication technology to transmit commands, alarms, and events.
Key features:
  • Two-way communication.
  • Advanced anti-sabotage.
  • Block encryption featuring a dynamic key.
  • Instant notifications.
  • Remote configuration via the Ajax apps.

Sensitive elements
Sensitive elements smoke sensor
heat sensor
CO (carbon monoxide) sensor
Smoke detection
Sensitive element double-spectrum optical sensor

Recognizes smoke by the size of particles in the air.

Protection from false alarms Does not react to water vapor.
Patented smoke chamber Protects the smoke sensor from dust, dirt, and insects.
Dangerous temperature detection
Sensitive element according to the requirements for Class A1R heat 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
Carbon monoxide (CO) detection
Sensitive element chemical CO sensor
Alarm if accumulated dose of CO is exceeded more than 50 ppm (0.005%) — no more than in 90 minutes
more than 100 ppm (0.01%) — no more than in 40 minutes
more than 300 ppm (0.03%) — no more than in 3 minutes

CO concentration of 400 ppm (0.04%) within 3 hours can be life-threatening. The detector stops notifying about the dangerous level of carbon monoxide when the concentration drops to 50 ppm (0.005%) within one minute.

Sensor life 10 years

After 10 years of operation, the detector must be replaced with a new one.

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 via primary interconnection

If one of the fire detectors in the system detects a threat, it sends an alarm to the hub. Within 20 seconds, the hub initiates an interconnected alarm and sends data to Ajax apps.

via fallback interconnection1

At the same time with notifying the hub, the initiating detector sends an alarm directly to other detectors. All connected detectors activate the buzzer within a minute. It will work even in the worst-case scenario of losing connection with the hub.

1 Fallback interconnected alarm is available only for FireProtect 2 detectors with firmware version 5.59.2.ХХ or later. Devices that support the fallback interconnected alarm are marked on the package with a “Fallback interconnect supported” label.

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, if the battery is low.

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, runs the detector test when pressed. In the event of an alarm or malfunction, the pressing turns off the detector sound notification.
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.
