  • Smoke detectors, to PGM2 what will be the best for Heat detectors on a DSC alarm?

    Heat only detectors do not go to a PGM. They simply go to a zone.

  • Can the System Sensor 5604 be used in a 4 wire system by connecting only the alarm circuit wires? Can the sensor be located between the control panel and the last smoke detector/EOL?

    It is not recommended to mix smokes on the same circuit as heats.
