The fire heat (fixed temperature) SPT-2A is designed for the control of ambient temperature in enclosed premises of various buildings and constructions.

When the ambient temperature in a guarded room 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 is counted on the continuous 24-hours operating along with a control panel by 2-wire alarm loops (D.C. and A.C.) with the nominal power voltage 12 or 24 V. The detector provides the indication of the standby mode of the operation.

The detector complies with A2 class on NPB 85-2000, NPB 57-97, and NPB 76-98.
