Connecting auxiliary/booster power supplies
UL requires that you monitor secondary power sources for loss
of AC power. Upon loss of AC power, the control panel must
provide an audible and visible trouble signal. In addition, remote
station, central station, and proprietary-type protected premises
units must transmit a trouble signal off-premises after a one- to
three-hour delay.
To meet UL requirements you need to connect a SIGA-CC1 (or
SIGA-CC1S) and a SIGA-CT1 to the booster supply. The SIGA-
CC1 is used to activate the booster supply and to signal common
troubles. The SIGA-CT1 is used to signal booster supply AC
power failures.
Installation
Mount the SIGA-CC1 and SIGA-CT1 inside the booster supply
as described in the booster supply’s technical documentation and
wire them as shown in Figure 32.
Configuration
Booster supply
Set SW2-6 to ON. This configures the booster supply’s Trouble
relay to close only on loss of AC power. All other booster
troubles are signaled through the sense circuits.
Note: In Figure 32, the booster supply is configured so that
Sense 1 controls all four NACs. For DIP switch settings for this
and other booster supply configurations, refer to the booster
supply’s technical reference manual.
Signature modules
Configure the Signature modules as described below.
