Simplex TrueAlarm Analogue Addressable Detector Base 4098-9789EA

TrueAlarm detector bases contain integral addressable electronics that constantly monitor the status of the detachable photoelectric, ionisation, or heat detectors. Each detector’s output is digitised and transmitted to the system CIE every four seconds. Since TrueAlarm detectors use the same base, different detector types can be easily interchanged to meet specific location requirements, for example, during building construction, or when conditions are temporarily dusty. Instead of covering the smoke detectors(causing them to be disabled), heat detectors may be installed without reprogramming the CIE. Although the CIE will indicate an incorrect detector type, the heat detector will operate at a default sensitivity maintaining building protection at that location.
