Building Management System
This device can be integrated with a Building Management System (BMS), a home alarm system, or be used as part
of a boiler low voltage safety limit to make or break a circuit on both gases separately, (valve open or valve closed)
depending on the system.
These switches can be used for a variety of purposes including triggering alarm contacts, operating and external relay
for multiple appliance shutdown and generating status signals for a BMS system.
Operation
Initial Power Up
When power is removed manually or due to an unpredicted power failure the CO and NG BMS circuit will change state
switching off boilers/appliances via a limit switch if configured to do so!
When electrical power is supplied, press, and hold the touch sensor on the front cover for ~3 seconds.
The detector enters a stabilisation phase for approximately one minute – during this period the device is not
operational. If the detector has been configured to 'Auto-Reset' – your device will power up automatically
when electrical power is supplied. To turn your device off, remove/isolate electrical power supply.
Digital Indications
Alarm Set Points
When the detector reaches alarm levels the maximum concentration detected will be saved and the screen value will switch
between the maximum (MAX) and the real time current value!
When the device has reached an alarm state, the concentration indicator will remain red even if gas levels are safe until the
device is reset by pressing the touch sensor once!
An audible buzzer will sound if the internal buzzer switch is on!
