This 4098 9791 SIMPLEX Truealarm Sensor Base is a reliable and accurate sensor base, designed to provide high quality detection of potential fire hazards. With its advanced technology and precise measurements, it ensures maximum safety and protection for your space. Easy to install and durable, it is an essential component for any fire detection system. TrueAlarm sensor bases contain integral addressable electronics that constantly monitor the status of the detachable photoelectric or heat sensors. Each sensor's output is digitized and transmitted to the system fire alarm control panel every four seconds. Since TrueAlarm sensors use the same base, different sensor types can be easily interchanged to meet specific location requirements. This feature also allows intentional sensor substitution during building construction. When conditions are temporarily dusty, instead of covering the smoke sensors (causing them to be disabled), heat sensors may be installed without reprogramming the control panel. Although the control panel will indicate an incorrect sensor type, the heat sensor will operate at a default sensitivity providing heat detection for building protection at that location. This flexibility and adaptability make TrueAlarm sensors an ideal choice for complex and dynamic environments, ensuring reliable fire detection and protection at all times.
