CGA G-13 code, specifically section 12.2.1.5, states that an activation of the deluge sprinkler system
should result in a shutdown of the silane (SiH
4
) source. The customer should include this signal as part
of the Life Safety System input to the module, shown on the electrical installation drawing, Appendix
A of this manual.
Supervised Inputs
The system supports two supervised inputs from the customer interface. Supervised inputs are digital
inputs, which are monitored via a window comparator. These inputs are monitored for normal
operation, alarm type, and fault conditions.
A normally open switch is to be used as an input device. This switch must have a 10 kilo-ohm resistor
in parallel with the contacts. When the switch contacts are open the circuit will provide a signal, which
represents a normal operating condition. When the switch contacts are closed, the circuit will provide
a signal which indicates an alarm condition. An open wire in this circuit, or a short circuit, will
produce an out of range signal, which indicates a circuit fault.
Switch contacts must be rated for 20ma @ 24VDC. Switch contacts must be dry contact and external
wiring should not have any form of power applied to them.
Typically, supervised inputs are used with the life safety system. Figure 2-16 shows the supervisor
input wiring for use with the life safety system.
