Chapter 5: Installation
108 EST3X Technical Reference Manual
Figure 24 on page 109 shows an auxiliary/booster power supply being used to
power the NAC, to provide synchronization and 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.
Notes
• 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.
• All wiring is supervised and power-limited unless otherwise noted.
• Install a PAM-1 or equivalent listed relay only when you are required to
supervise the 200 mA AUX circuit wiring.
• Configure Sense 1 and Sense 2 operation for Genesis Master mode and NAC
operation for “continuous.” See the documentation received with the
auxiliary/booster supply for details.
• Use a CC1S if you want to maintain signal synchronization across multiple
auxiliary/booster supplies on the same Signature loop.
