Description

The SenTRI Single Input Module is an analogue addressable interface, designed to integrate external devices into the SMS SenTRI fire alarm system. This allows for the incorporation of devices like sprinkler flow switches and conventional detectors lacking built-in addressable technology. Each module possesses a unique address on the system loop, enabling accurate identification and monitoring of the status of the connected devices.

Supporting both normally open (NO) and normally closed (NC) contact inputs, the module offers adaptability for various external signal types. A built-in loop isolator maintains system integrity by isolating faults, ensuring uninterrupted communication across the fire detection network.

This compact module is designed for a wide operating temperature range, from -10°C to +60°C, and has an ingress protection rating of IP31 (plastic box) or estimated IP40 (metal box). It is compliant with EN54-17 and EN54-18 standards and is LPCB approved.

Regarding panel compatibility, the module is compatible with Loop = V4.35 and Main Control Card = V4.37. The load factor specifications include switch inputs, relay outputs, zone inputs, and LED outputs, each with a maximum number per loop. The module weighs 92g and can operate in relative humidity up to 95%.
