Figure 5-4 shows a single SIGA-CC1 switching an NAC on or
off. The G1M module provides signal synchronization for the
temporal horn/strobe appliances.
As in earlier examples, this circuit allows for independent
silencing of the audible appliances. This operation is provided by
the SIGA-CR module, which opens or closes the circuit between
S+ and H+ on the G1M module. In this case, however, you must
program the operation of the SIGA-CR. The project settings for
signal silence operation will not determine the operation of the
audible appliances in this NAC.
Note also, that this application could be implemented with a
SIGA-CC1S module. The SIGA-CC1S provides signal
synchronization compatible with the operation of the G1M
module.
The advantage to using a SIGA-CC1S module is that the NAC
would then be synchronized with other NACs on the Signature
data circuit.
