Power Supplies
SERIES PS873
The series PS873 power supply is designed to operate a wide
variety of electrical products. EL panics require 871-2 PCB
minimum. The regulated output power is field selectable for
either 24VDC @ 2 ampere or 12VDC @ 4 ampere. Standard
input 120VAC @ 1.0 ampere or 240VAC @ 0.5 ampere available.
Enclosure is 10" high x 12
1 ⁄
2
" wide x 5" deep (254mm x 323mm
x 127mm), gray with a hinged cover and constructed of heavy
19 gauge steel. Five
1 ⁄
2
" x 3 ⁄
4
" (13mm x 19mm) knockout holes
are provided for conduit connection. Terminal block will accept
up to 12 gauge wire.
The PS873 can be ordered with three standard options: Key
lock secures the cover to eliminate tampering and provides
safety; Battery backup provides two hours backup power at full
load during a A.C. power failure. Batteries will automatically
recharge when failed power is restored. Fire Alarm provides
input for a normally closed fire alarm contact. When the fire
alarm contact is “open”, power to locks or other component is
removed. Restoring power is field selectable for automatic
or manual.
Eight standard configurations:
PS873 Standard
PS873K With keylock
PS873B With battery
PS873BK With battery and keylock
PS873FA With fire alarm
PS873K-FA With keylock and fire alarm
PS873B-FA With battery and fire alarm
PS873BK-FA With battery, keylock and fire alarm
The series PS873 is available with several optional circuit cards
to provide system flexibility. The power supply will accept one
or a combination of any two cards.
Factory or Field Installed Circuit Cards:
871-2, Two Zone controller provides two inputs and two
outputs. Will operate one or two EL exit devices. Use suffix “-2”
for factory installed, example PS873-2.
873-AL, Alarm function monitors 1 or 2 zones and provides
alarm output, upon detecting a door in the open position.
Delayed alarming is selectable from 5 to 75 seconds. Use suffix
“-AL” for factory installed, example PS873-AL
873-AO, Auto Operator function coordinates the release of one
or two locks and signals an auto-operator to open a door.
Signaling the auto operator can be performed in two methods;
by receiving a signal from a monitoring switch that the lock is
unlatched, or upon expiration of a time delay triggered by a
“RX” type input switch. Use suffix “-AO” for factory installed,
example PS873-AO
873-SI, Security/Safety Interlock provide interlock function for
two zones. When combined with a second 873-SI card, the
inter-locking of groups are available in two, three or four zones.
Safety interlock is available, consult factory for additional
information. Use suffix “-SI” for factory installed, example
PS873-SI
873-4TD, Four Zone controller with Time Delay provides four
inputs and four outputs with time delay. Time delay is field
selectable from 0 to 75 seconds, in intervals of 5 seconds. Will
operate up to 4 EL devices. Use suffix “-4TD” for factory
installed, example PS873-4TD
873-AC, Access Control provides supervision of one zone using
an electromagnetic lock. Input signals required are: access
control contact, motion detector contact, and motion detector
override contact. FA, Fire Alarm option is required. Use suffix “-AC”
for factory installed, example PS873-AC
Factory Installed Only Circuit Card
873-DE, Delayed Egress provides 15 second delay release from
pushbar activation to electro-magnetic lock release. Ideal
function for use with Locknetics electromagnetic locks, will
operate two zones simultaneously. To operate two separate
zones, a second 873-DE card is required. UL listed component,
when used as part of a Von Duprin delayed egress system. Use
suffix “- DE”, example, PS873-DE.
Note: “DE” cards CANNOT be combined with any other optional cards.
