The fire heat fixed temperature/rate-of-rise detector with the standby mode indication SPT-3A is designed for the control of ambient temperature in enclosed premises of different buildings and constructions. When ambient temperature or the velocity of temperature growth exceeds the threshold value, the detector forms the “Fire” signal for a control panel. The “Fire” mode is induced by a red optical indicator.
The detector provides the indication of the standby mode of operation by short-term flashes of a red optical indicator.
The detector is counted on the continuous 24-hours operation along with a control panel by the 2-wire alarm loop (D.C. and A.C.) with the nominal power voltage of a loop 12 or 24 V.
The detector complies with the À2R on NPB 85-2000, NPB 57-97, NPB 76-98.
