1.7 Sentro Module
Plug-in pre-calibrated sensing module with standardised output data.
• The sensing module stores all the necessary data about its type identification,
sensing range and specific calibration. This data is automatically recognised by
the Sentro when the sensing module is loaded into the module bay
• The sensing modules are pre-calibrated so they can be replaced at any time by
a replacement sensing module
• The sensing module will identify itself when plugged into the sensor housing
and auto configuration will take place
• All Sentro sensing modules have two output alarm signals for General alarm
and High alarm. Default values are entered during manufacture and these can
be changed to preferred values
• The two alarm signals can be set to illuminate built-in flashing LED indicators
• The two alarm signals can be set to operate the General alarm and High alarm
relays on the Dual Relay Contact version of the Sentro.
