Wiring the Beacon 110
This section describes procedures to connect the AC power source, DC power source,
external alarm(s), recorder, and detector head.
WARNING: Make all connections to the Beacon 110 before you plug in or turn on the AC or
DC power source. Before you make any wiring adjustments, always verify that
all power sources are not live.
Connecting the AC Power Source
NOTE: If you are using DC power as the primary power source, go to the next section,
“Connecting the DC Power Source”.
The AC in terminal strip will accept 24 - 14 AWG wire. All connections to building electrical
systems must be installed in accordance with local requirements and must be installed by
qualified personnel. If this equipment is used in a manner not specified by the
manufacturer, the protection provided by the equipment may be impaired. Install an
appropriate switch or circuit breaker in the AC line close to the Beacon 110 that meets the
local electrical code and within easy reach of the operator. The switch or circuit breaker
must be marked as the disconnecting device for the Beacon 110.
Perform the following procedure to connect the AC power source to the Beacon 110.
WARNING: Verify that the power source is unplugged or turned off before you continue
with this procedure.
