INDEPENDENT SYSTEM LATCH RETRACTION
When congured for Independent Door Operation, DEVICE ONE and DEVICE TWO outputs are controlled independently by their
own separate input. A momentary switch closure across terminals 15 and 16 of TB3 will pull back DEVICE ONE only. A momentary
switch closure across terminals 13 and 14 of TB3 will pull back DEVICE TWO. No more than one device can be used per output. Use
this option for applications requiring two single door systems or two pair door systems using one device on each pair of doors. To
change to the independent system latch retraction, move the program jumper PJ1 from between the middle post and the end post,
marked “Independent”.
NOTE: When using the Independent system, DEVICE ONE and DEVICE TWO can never be activated at the same time. In the event that
both input switches are actuated simultaneously, DEVICE ONE will always activate rst, followed by DEVICE TWO.
When using a momentary, normally open switch for activating latch retraction, adjust potentiometer DEV 1 (R36) or DEV 2 (R28) on
the p.c. board to the desired latch retraction hold time from approximately 10 to 30 seconds. Turn the potentiometer clockwise to
increase the hold time.
When using normally open contacts from a keypad, card reader or a maintain switch, turn potentiometer DEV 1 (R36) or DEV 2
(R28) fully counterclockwise to the minimum hold time. A contact closure will activate latch retraction. Upon re-opening the
contacts, the device will latch within 10 seconds.
OPERATION WITH AUTOMATIC DOOR OPERATION
The 782 is provided with two outputs (one output associated with DEVICE ONE and the other output associated with DEVICE TWO)
for controlling separate automatic door operators. Each output consists of normally open relay contacts that are eld wired directly
to the “DOOR ACTIVATION” input of the automatic door operator. These outputs are activated within a moment after activation of
their corresponding devices to allow time for the doors to be fully unlatched before automatic opening begins.
Hold time potentiometers DEV 1 (R36) and DEV 2 (R28) are factory set to 10 seconds, which is appropriate for using this controller
with automatic door operators. When the hold time expires, power is removed from the exit device and the signal to the auto door
operator input is terminated, thus allowing the operator’s “DOOR HOLD OPEN” delay to time out and close the door.
NOTE: When using the paired system latch retraction method with an automatic door operator interface and both devices are being
used, the automatic door operator control input must be wired to the 782 automatic door operator output for DEVICE TWO
(TB3, terminals 5 and 6).
OPERATION WITH FIRE ALARM
The 782 can be wired to the re alarm relay normally closed contacts. When a re alarm occurs, any door this is currently unlatched,
whether by momentary time delay or by maintained switch, will immediately latch secure. During the time that the re alarm is
active, electronic control of the automatic door opening system by wall switch, card reader, keypad, etc., is disabled. The door then
can only be opened manually.
The 782 comes from the factory set up for use with a re alarm interface. If a re alarm interface is not to be used with the controller,
move the program jumper PJ2 from between the middle post and the end post, marked “ENABLE” (Fire Alarm Enabled), to the
middle post and the end post, marked “DISABLE” (Fire Alarm Disabled) .
NOTE: Maximum current through re alarm relay contacts is 120mA @ 25-38VDC UL Note: The 782’s Operation with Fire Alarm
feature has not been evaluated by UL. 80-9477-
