and side. The PS-426BB mu
st not be installed
outdoors.

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.

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 acti
ve. Factory set to five second
s, 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 contac
ts, 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.
