SenTRI Sensors

This following is short information on the SenTRI Sensor product range. The SenTRI 

product integrates smoke, heat with electronic sounder and LED flasher in one 

assembly.

Full information on SenTRI Devices can be downloaded from www.smstoolbox.co.uk 

by registered users.

Base

The base has terminals for external cables, for the wiring of loop circuit and monitored 

input or output circuit. Any SenTRI Sensor device can be plugged into an SenTRI base.

IP21 Base

A IP21 Base Gasket prevent water damage from dripping water from the ceiling.

An optional label (Part No: 805576) can be fitted to the base. The label can be marked

up with device location information.

Indicators

The SenTRI Sensor has a red LED that gives an indication in the event of a fire. The 

LED can be configured to flash periodically, as an ‘in operation’ confirmation, this 

indication is given system-wide at all SenTRI Sensor devices. 

Dust Cover

A dust cover is supplied with the SenTRI sensor device, to prevent dust from building 

work contaminating the sensor. The cover is removed prior to the commissioning of the 

fire alarm system.
