DORMA MODEL PS-426BB
POWER SUPPLY
INSTALLATION INSTRUCTIONS
INSTALLATION
Install in accordance with NFPA 70.
The PS-426BB enclosure should be securely fastened to the wall using the four 1/4 inch
diameter mounting holes located in the back of the box. Position the enclosure so that the
battery compartment is located on the left-hand side. The PS-426BB must not be installed
outdoors.
For the 120VAC power input, terminal block TB1 will accommodate up to 12 AWG wire (solid).
Conduit must be used to provide an adequate earth ground to the enclosure.
NOTE: The maximum input current is 1.08A with a 12.6A inrush current.
Features:
Up to 1.95 Amps Load Capacity
Class 2 Rated Outputs
Overload, Over Voltage, and Short Circuit

The PS-426BB is designed to be used with all exit devices modified for ESB electric latch
retraction. Use the chart below to determine the correct wire gauge per given length of two-
conductor cable that will be run from the PS-426BB to each exit device. Do not exceed the
maximum length listed with each wire gauge.
WIRE GAUGE MAXIMUM LENGTH OF TWO-CONDUCTOR CABLE
16 AWG 40 FEET
14 AWG 60 FEET
12 AWG 100 FEET
Up to two devices can be used with the PS-426BB. If only one device is to be used, wire to
the “DEVICE ONE” location at TB3, terminals 5 and 6.
STANDARD OPERATION
The PS-426BB is provided with two inputs: one used for momentarily retracting latches
sequentially, followed by a signal to activate the automatic door operator; the other used with a
maintain switch for sequentially retracting latches only. This system will work for single door
applications or on a pair of doors using a device on one or both leaves.
Connect a momentary, normally open switch across terminals 1 and 2 of terminal block TB3.
Closing this switch momentarily will retract the latch of DEVICE ONE and DEVICE TWO
sequentially and follow with a dry contact closure signal to the automatic door operator. Pot
R2 is used to control the length of time that the latch(es) remain retracted and the signal to the
automatic door operator remains active. Factory set to five seconds, pot R2 (located at the top
of the p.c. board) can be field adjusted to the desired delay time from 2 to 8 seconds. Turn the
pot clockwise to increase the delay time.
When using normally open contacts from a keypad or card reader with built-in time delay, turn
pot R2 fully counterclockwise to the minimum delay time (approx. 2 sec.). A contact closure
will activate latch retraction and activate the automatic door operator. The device(s) will latch
and the signal to the automatic door operator will cancel within 2 seconds after the keypad or
card reader delay times out.
NOTE: Pot R4 is not used; do not adjust.
Connect a maintain switch across terminals 7 and 8 of terminal block TB3. Closing this switch
will sequentially retract the latch of DEVICE ONE and DEVICE TWO, but will not activate the
automatic door operator. Upon opening the switch contacts, both devices will immediately
latch (no delay before latching).
Connect ESB DEVICE ONE to TB3, terminals 5 and 6; If a second ESB device is used,
connect the ESB DEVICE TWO to TB3, terminals 11 and 12. The automatic door operator
output, TB3, terminals 9 and 10, consists of normally open relay contacts that are field wired
directly to the “DOOR ACTIVATION” input of the automatic door operator.

NOTE: P.C. board program jumper PJ1 must always be left in place between the middle post
and the end post marked “S”.
SOLENOID ASSEMBLIES - THEORY OF OPERATION.
This device contains a powerful solenoid that performs both pulling and holding functions. An
initial high current pulse occurs each time output voltage is applied to the device. After the
pulse, the solenoid switches over to a "holding" state by way of frequency modulation which
reduces the current to allow the solenoid to run at a cooler temperature.
OPERATION WITH FIRE ALARM
The PS-426BB can be wired to the fire alarm relay normally closed contacts. When a fire
alarm occurs, any door that is currently unlatched, whether by momentary time delay or by
maintained switch, will immediately latch secure. During the time that the fire alarm is active,
electronic control of the automatic door opening system by wall switch, card reader, keypad,
etc., is disabled. The door can only be opened manually.
The PS-426BB comes from the factory set up for use without fire alarm interface. If the fire
alarm is to be used with this unit, move the program jumper PJ2 from between the middle post
and the end post marked “FA DIS” (Fire Alarm Disabled), to between the middle post and the
end post marked “FA EN” (Fire Alarm Enabled).
NOTE: The current drawn through fire alarm relay contacts will be 120mA @ 24VDC.
AUXILIARY POWER SOURCE OUTPUT
A constant, power limited auxiliary output is provided for powering a variety of load devices,
such as keypads, motion sensors, annunciator panels, electromagnetic door holders, relays,
LEDs, etc.
Auxiliary Output Range:
o 26.1V – 27.2V, Nominal (commercial power applied)
o 15.4V – 22.5V, Standby Battery Power (85% nominal to full charge range)
Due to the significantly lower voltage range resulting from the unit running on standby battery
power, it is recommended to use load devices with a rated input of 12 – 24 volts DC (or
AC/DC).
CAUTION: CHECK WITH THE MANUFACTURER TO MAKE SURE THE LOAD DEVICE
WILL OPERATE PROPERLY AND SAFELY WITHIN THE HIGHER VOLTAGE
RANGE WHEN THE PS-426BB IS RUNNING ON COMMERCIAL POWER.
