Heat detector

Heat detector:

The 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.

It is ideal for kitchens, garages, cellars, boiler rooms, attics and other areas where there are normally high levels of fumes, smoke or dust which preclude the use of Smoke Alarms due to the risk of false alarms. All the Heat Alarms and Smoke Alarms should be interconnected to ensure the early warning will be heard, particularly by somebody sleeping. A properly designed early warning fire system ensures the alarm is given before the escape routes become blocked with smoke. Therefore there must be Smoke Alarms along the escape routes as Heat Alarms would not give sufficient warning. However, a fire in a closed room (e.g. kitchen) adjoining the escape route, can eventually cause the corridor to become smoke-logged due to smoke leaking out from around the door before adequate warning can be given by detectors in the corridor. A heat Alarm in the closed room may give early warning of fire in that room.
