MANUAL
SPT-3B
HEAT DETECTORS
The detectors comply with EN 54-5:2000/A1:2002 A2R class.
The following abbreviations apply in the manual.
AL – alarm loop;
FACP – control panel.
1 PURPOSE
1.1 The SPT-3B heat detectors feature:
- fixed temperature/rate-of-rise detection,
- LED indication of standby mode,
- remote reset,
- 4-wire connection to 12V FACP or fire intruder CP,
- indoor use.
1.2 Either when exceeding the threshold ambient temperature value the detector issues the alarm
signal for FACP or if the ambient temperature rate-of-rise is high even if the initial temperature much
lower than regular temperature of detector operation.
1.3 The Fire mode is indicated with the red LED indicator (steadily lit – DCAL, flashing– ACAL).
1.4 The red LED flashes every 1-2 sec in standby mode.
