16 Beacon 110 Operator’s Manual
Connecting External Alarms
Perform the following procedure to connect external alarms to the Beacon 110.
WARNING: Do not connect external alarms to the External DC In terminals on the
controller terminal strip.
1. Turn off or unplug all incoming power to the Beacon 110.
2. Open the housing door, then place the power switch in the OFF position.
CAUTION: The power switch does not control DC input power.
3. Locate the alarm terminal strip. See Figure 1 “Beacon 110 Component Location” on
page 4, to assist you in locating the alarm terminal strip.
4. Install an appropriately rated cable bushing or conduit in the left conduit hub on the
bottom of the Beacon 110 housing. This hub is typically used for power wiring and
may already have conduit or other fittings installed because of this.
CAUTION: Only use the two factory installed conduit hubs on the bottom of the
housing for wire entry into the housing. Do not drill the housing for any
reason. See “Routing Wiring Into the Beacon 110 Housing” on page 13 for
more information.
5. Guide the wiring of the external alarm through the left conduit hub on the bottom of the
Beacon 110 housing.
CAUTION: Do not route the external alarm wiring and detector wiring through the same
conduit hub. The external alarm wiring may disrupt the transmission of the
detector signal to the Beacon 110.
6. Connect the leads from the external alarm to the appropriate terminals on the alarm
terminal strip as shown in Figure 9 to obtain the desired operation.
