The CHQ-PCM(SCI) is a loop powered input/output
module with four independent changeover relay outputs
and four monitored inputs.
The outputs feature N/O and N/C volt free contacts and
can be driven separately under the control of the fire
alarm panel, to be used for the control of devices such
as dampers or for plant and equipment shutdown.
The four inputs are provided for local fire and fault
monitoring and these are fully monitored for open and
short circuit, which if required, can be enabled or
disabled in pairs using a two-way DIL switch. Note:-
The state of the relay contacts will be indeterminate
until the unit is powered.
