Technical data sheet
| 38104.10.BL1 | |
| Communication | |
| Jeweler communication technology | Proprietary wireless communication technology to transmit commands, alarms, and events. Key features:
|
| Radio frequency bands | 866.0 - 866.5 MHz 868.0 - 868.6 MHz 868.7 - 869.2 MHz 905.0 - 926.5 MHz 915.85 - 926.5 MHz 921.0 - 922.0 MHz Depence on the sales reaction |
| Maximum effective radiated power (ERP) | up to 20 mW Automatic power control to reduce power consumption and radio interference. |
| Radio signal modulation | GFSK |
| Radio signal range | Up to 1,300 m up to 4,200 ft Between the detector and a hub (or radio signal range extender) in an open space. |
| Encrypted radio communication | All the data stored and transmitted are protected by block encryption featuring a dynamic key. |
| Frequency hopping | To prevent radio interference and jamming |
| 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 at temperatures above 140 °F |
| Temperature spike alarm | when the temperature rises more than 30 °C in 30 minutes or less when the temperature rises more than 86 °F in 30 minutes or less |
| Additional features | |
| Built-in siren | 85 dB volume at a distance of 3 meters 85 dB volume at a distance of 9 ft 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 |
|
| 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. |
| Recommendations | The device is designed for indoor use only. |
| Sabotage protection | |
| Tampering 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 Jeweler or Jeweller/Fibra settings |
