Technical data sheet
| 60828.173.WH1 | |
| 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 1,700 m up to 5,500 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 |
| Dangerous temperature detection | |
| Sensitive element | according to the requirements for Class A1 heat detectors Requirements of EN 54-5 and BS 5446-2 standards |
| High temperature alarm | at temperatures above 64 °C at temperatures above 147 °F |
| Temperature spike alarm | when the temperature rises more than 10°C 50°F in 1 minute 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 | 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, 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, pressing turns off the detector sound notification. |
| External power supply | 110–240 V~, 50/60 Hz The phase and neutral cables from the external power supply should be connected to the WAGO terminals on SmartBracket mounting panel. To remove the detector from SmartBracket, there is no need to disconnect the power cables. |
| Recommendations | The device is designed only for indoor installation SmartBracket mounting panel allows adjusting the position of the detector after installation. |
| 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 Jeweler or Jeweller/Fibra settings). The polling interval is fixed at 300 seconds. |
| Power supply | |
| Main | 110–240 V~, 50/60 Hz Up to 2W of mains power consumption. |
| Backup | 1 non-replaceable lithium battery Allows the detector to operate autonomously without the main power source. |
