Stable temperatures are often needed to prevent costly and irreparable property damage. A critical alert from a wireless temperature detector will allow you to take preventive measures before the temperature reaches a harmful level. The BT1 wireless temperature detector measures the ambient temperature and wirelessly transmits the results to the receiver. The temperature is displayed on the keypad screen, can be transmitted to the ALARMSERVER.NET cloud and viewed in a browser window or displayed in the SECOLINK PRO app.

BT1 works with P-series and S-series control panels or PAS-series control panels with EXT116S expansion module connected to the system bus. Advanced radio technology ensures reliable operation up to 100 metres in the building
