MAKE IT YOURS
FireProtect.
Wireless fire detector with temperature sensor that monitors security in the room twenty four hours a day and immediately notifies of smoke and sharp jumps in temperature.

Standards and certifications
FireProtect Jeweller · FP.Y.J. Manufacturer-listed marks; regional and installation conditions apply.
Smoke and heat detection, ready for everyday use.
FireProtect Jeweller combines photoelectric smoke detection and a temperature sensor. Its built-in siren can warn locally without a hub; a compatible Ajax hub adds notifications and interconnected alarms. Replaceable main and backup batteries support operation, while cleaning alerts help you maintain the smoke chamber.

Remote configuration and testing
Through the Ajax app with a connected hub
- 1Interconnection and app notifications require a compatible connected hub and enabled configuration. Activation follows the hub–detector polling interval.
- 2Battery life depends on settings and use. Batteries are replaceable; detector service life is separate.
- 3Measured in open space. Walls, obstructions and radio interference reduce range.

Protection in real places.



Two ways to detect signs of fire.
Photoelectric smoke sensing
An infrared emitter and a photoelectric receiver monitor the smoke chamber. Smoke changes the light reaching the receiver. HazeFlow analyses the smoke signal to help filter interference.
A local alarm. A connected response.
85 dB at 3 m
The detector can sound its own siren without a hub. It remains active regardless of whether the intrusion system is armed. Sound and light patterns distinguish alarms from maintenance warnings.
Main batteries, with a separate reserve.
Two CR2 batteries and a CR2032 backup
Two pre-installed CR2 batteries provide the main power, with up to 4 years of battery life. A separate CR2032 battery provides backup. The batteries are replaceable; respond to each low-battery indication and follow the replacement procedure.
Battery life varies with settings and use. Battery replacement does not reset the detector’s service life.
Keep the detector connected and supervised.
Jeweller radio
Encrypted two-way communication and device authentication help protect the connection. Frequency hopping and jamming detection support radio reliability. Ajax specifies up to 1,300 m between the device and a hub or range extender in open space.
Match the regional radio version and confirm exact hub compatibility. Walls and interference affect reception; test the signal at the installed position.
Install, pair and test.

Secure it on SmartBracket
Choose the position using the detector’s placement instructions, check radio reception, and fix SmartBracket securely. The supplied mounting panel lets you install the detector without opening its enclosure.
Indoor use only: 0 to +65 °C, humidity up to 80%, IP40. Keep the specified clearances from corners, beams, ventilation and sources of routine steam or cooking fumes.
Keep the smoke chamber ready.
Respond to cleaning alerts
The detector checks the smoke chamber and signals when dust needs to be removed. Follow Ajax’s cleaning procedure and test the detector afterwards. This generation requires that maintenance when the warning appears.
Plan for the detector’s service life.
Up to 10 years
The FireProtect Jeweller manual specifies a service life of up to 10 years. Replace the detector at the end of that period and act on earlier fault indications. Changing the batteries does not renew the sensors.

Communication
- Jeweller communication technology
- Two-way system communication for the functions specified for this model.
- Radio communication range
- up to 1,300 m Between the device and a hub (or a range extender) in an open space.
- Encrypted communication
- Encrypted device communication.
- Frequency hopping
- To prevent radio interference and jamming.
Sensitive elements
- Sensitive elements
- smoke sensor; heat sensor
Smoke detection
- Sensitive element
- photoelectric sensor
- False alarm prevention
- The HazeFlow software algorithm checks for smoke before activating the alarm. The system will ignore the first triggering and raise an alarm if the device detects the smoke again after 30 seconds during the second check.
Dangerous temperature detection
- Sensitive element
- thermistor
- High temperature alarm
- at temperatures above 60 °C
- Temperature spike alarm
- when the temperature rises more than 30 °C in 30 minutes or less
Additional features
- Built-in siren
- 85 dB volume at a distance of 3 meters Sound notification of alarms. Active until the reason for triggering is eliminated or until the user disables the notification.
- Interconnected fire detectors alarm
- All fire detectors in the system turn on built-in sirens if at least one detector registers an alarm. An interconnected fire detectors alarm is activated within one “hub–detector” polling interval.
- Indication
- LED; sound The indication shows the detector status and alarms.
- Touch button on the detector’s front panel
- In normal mode, pressing the button starts the smoke chamber test. In the case of an alarm or malfunction, pressing the button turns off the detector sound notification.
Sabotage protection
- Tamper alarm
- Notifications of attempts to detach the detector from the surface or remove it from the mounting panel.
- Protection against spoofing
- device authentication
- Communication loss detection
- after 36 s Detection time depends on the Jeweller or Jeweller/Fibra settings.
