Theory of Operation
The Adams Rite Power Supply (PS-SE) provides power and control for
up to two exit devices. Each exit device is controlled by a timer that is
initiated by a switch closure. The timer is user configured and holds the
exit device(s) in the unlatched position for 2
–60 seconds. At the end of
the selected time, the exit device(s) will re-latch. If the switch controlling
the exit device is held closed longer than the selected time, the exit
device remains unlatched until the controlling switch is released.
An optional mode is available allowing both retraction timers to activate
in response to closure of either switch.
The PS-SE is listed as an Exit Device, Access Control System unit to
UL305 and UL1012 requirements for power supplies and CAN / CSA -
C22.2.
Exit devices under the system control remain latched during a complete
power failure but always allow free mechanical egress.
Configuring the PS-SE
CAUTION
Damage to the PS-SE or to exit devices may occur if connections
are not made in accordance with the following procedure, or if
connections are bypassed or omitted.
Ensure the Primary Voltage
NOTE:
The PS-SE is rated
for 120 VAC only. Switch 2
(SW2) is factory preset for 120
VAC operation.
1. ENSURE the PS-SE is set
to 120 VAC.
