Building Management System Integration
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,

Wiring Applications
Gas Supply Controlled by ~120vAC Solenoid Valve
CAUTION: If you use a gas solenoid valve, please note that
standing pilots will need to be re-lit.
We do not recommend installing a gas solenoid valve with
standing pilots.
Gas Supply Controlled by 24vAC Solenoid Valve
When the GAS VALVE terminal is wired to a normally closed
(NC) gas solenoid valve, the device can be used to isolate
gas supply for multiple appliances.
The diagram shown opposite uses an external transformer (not
supplied) to close a 24vAC gas solenoid valve that could
supply gas to one or more appliances.
CAUTION: If you use a gas solenoid valve, please note that
standing pilots will need to be re-lit.
We do not recommend installing a gas solenoid valve with
standing pilots.
