Abort Feature (BG-12LRA only)
The operation and reset of the BG-12LRA agent release pull station is the same as the BG-12LR,
with the addition of the Abort Feature: The System Normal LED will stay illuminated when the
Agent Release Control Panel is "All Systems Normal." When the station has been activated, ini-
tiating the agent release process in the control panel, the System Activated LED will illuminate.
If the control panel has been configured to abort the releasing of an extinguishing agent,
then pushing and holding-in the abort switch will cancel the agent release sequence. Please
refer to the respective agent release control panel manual for further instructions about us-
ing the Abort feature.
Abort Plate Wiring (BG-12LRA only)
Connect the wiring from the agent release control panel's Abort Circuit to the wire leads
D&E of the normally open abort switch. Connect 24 VDC (+) to a form-c relay, this relay
shall be called the Release Relay. Connect the relay's normally closed contact to the System
Normal LED wire lead A. Connect the relays normally open contact to the System Activated
LED wire lead B. Connect the 24 VDC (–) to the LED assembly ground wire C.

are fully completed. Do not use software disable functions in the panel as lockout. For ADA
compliance, if the clear floor space only allows forward approach to an object, the maxi-
mum forward reach height allowed is 48 inches (121.92cm). If the clear floor space allows
parallel approach by a person in a wheelchair, the maximum side reach height allowed is
54 inches (137.16cm).
