Teletek SensoIRIS M140 IS Addressable Multi-Sensor Detector with Built-in Isolator

The Teletek SensoIRIS M140 IS is a high-performance analogue addressable multi-sensor detector that provides comprehensive fire protection by monitoring both smoke density and temperature variations. Designed for use with Teletek’s TTE protocol panels, it features an integrated short-circuit isolator that maintains loop integrity during wiring faults. With five programmable operating modes and adjustable sensitivity levels, the M140 IS is highly adaptable to various environmental conditions, making it ideal for hotels, offices, and industrial sites where minimizing false alarms is critical. Fully compliant with EN 54-5, 7, and 17, this detector offers a robust, intelligent, and easy-to-maintain solution for modern life safety systems. Technical Specifications ? Brand: Teletek ?
