Typical circuits

The circuit diagrams that follow use the term zone to indicate

notification zones as defined in UL 864.

“Notification zone: An area covered by notification appliances that are activated simultaneously.”

Figure 5-1 shows a typical application of the 3-IDC8/4 module to support two notification zones. In this example, power is being supplied from the EST3 rail, and the jumpers (JP1 through

JP4) are set accordingly.

It is also possible to create a similar application that uses external power, supplied to NAC 1/2 IN and NAC 5/6 IN. Refer to the 3-IDC8/4 installation sheet for wiring details and the required jumper settings.

In Figure 5-1, both zones are configured with separate NAC circuits for audible and visible appliances. NAC 1 and NAC 5 are programmed as visible device types, and NAC 2 and NAC 6 as audible device types. This means that the signal silence function can be configured to silence only the horns.

Separating the visible and audible devices is optional and may not be required for your project. Refer to the Genesis Signal

Master installation sheet for additional configurations and wiring details.

Figure 5-3 Shows two NACs on a Signature data circuit. Each

NAC is controlled by a SIGA-CC1S module, one for audible appliances, and one for visible appliances.

As in Figure 5-1, this configuration allows the audible appliances to be silenced independently of the visible appliances. This operation is optional, and may or may not be required for your project.

The SIGA-CC1S modules provide signal synchronization for both NACs.

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.

Installation

Figure 5-5 shows an auxiliary/booster power supply being used to power the NAC, to provide synchronization, and to provide horn silence capability. Because the auxiliary/booster supply has the ability to silence the horn circuit, this application can be created using only the Signature loop wiring.

The SIGA-CT1 module monitors the power supply for AC failure. The SIGA-CR module signals the power supply to turn the horns on or off. The SIGA-CC1 module signals the power supply when the system goes into alarm, turning the NAC on.

Note that the power supply can only synchronize the notification appliances to which it is connected. If you need to synchronize several similar NACs on the same Signature loop, you can use a

SIGA-CC1S module in place of the SIGA-CC1.
