Connecting auxiliary/booster power supplies
UL requires that you monitor secondary power sources housed in auxiliary and
booster power supply enclosures for loss of AC power to ensure the following:
• Upon loss of AC power, the control panel must provide an audible and visible
trouble signal
• Remote station, central station, and proprietary-type protected premises units
must transmit a trouble signal off-premises
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.
Mount the SIGA-CC1 and SIGA-CT1 inside the booster supply cabinet as
described in the technical documentation received with booster supply. Connect
field wiring as shown in Figure 31 on page 124.
