Indicator turns green when operator
signal is active
Terminals are connected
to a SPDT dry contact relay
Terminal 14 is common
Terminal 13 is normally closed
Terminal 15 is normally open

PWA 102879 Electronic Latch Retraction Controller
I/O and Quick Reference Operating Information
Door Operator Signal Delay
Door operator signal is triggered
after latch retraction and time is
adjustable from 0.5 to 3 seconds.
Operator signal delay time
differential is adjusted by R21
Turn CW to increase delay time
Use a normally open dry contact switch,
close to operate. Terminals are electrically
equivalent.
Important: Observe Polarity when connecting
output wires

DETEX Model 81-800
Connection Diagram and Instructions
The 81-800 is a regulated and filtered power supply.
It has a selectable output voltage of either 12 or 24 volts DC.
For Detex systems always select 24 volts DC.
Refer to the drawing of the power supply/controller for connections
and adjustments. All connections and adjustment must be made with
the power supply de-energized
AND
main power switch (item 3) in
the OFF position.
1: Main power connection. Observe correct terminal connections. Color
code requires connections made per NFPA72. Leave circuit
de-energized while installing and servicing unit.
2: Fire loop control. The fire loop control is bypassed with a factory
jumper. This allows the unit to operate independently and does not
require any external connections to operate. If connections to the
building fire alarm system are required, remove jumper plate
A
between
the (-) and (C)terminals. Connect the two wires from the building fire
system to these terminals. The power supply will operate normally as
long as the connection between the (-) and (C) is maintained. When the
building fire alarm system opens the circuit, the power supply
de-energizes the output voltage. Fire loop uses 24 volt sense voltage.
