Final steps
Operation
5.1 Determine power supply
Fig.12
5.1.1 Determine power supply and unit voltage type:
24VAC/24VDC.
CAUTION! DO NOT CONNECT 120VAC TO A 24 VOLT
UNIT TYPE!!!
5.1.2 Connect power supply wires, one (1) to terminal
block one (1) to bypass switch.
5.1.3 Connect other bypass switch wire to terminal
block. (Terminal block can be removed for easier
wiring).
5.1.4 Slide wiring connection cover over wire
connections.

Final steps
CAUTION! IMPROPER
VOLTAGE TO UNIT, WILL
RESULT IN DAMAGE TO UNIT
AND VOID WARRANTY.
NOTE: All wiring must comply with
national, state and local electrical
codes.
NOTE: This
connection is not
polarity dependent.
Terminal block 18
AWG max.
1. After installation is completed, recheck all connections. Apply power to units.
2. Open door so slide block engages with hold open assembly.
3. Advise fire officials prior to testing.
4. Activate system into alarm so the electromagnet releases and the doors close.
5. If the closer is used in conjunction with a detectored unit, trip the test switch of the main closer detector as explained in the test
procedure for that unit. After a short time delay, the hold open electromagnet of both units will release and the doors will close.
Resetting the test switch will allow the units to return to standby.
5.2 Final steps
IMPORTANT: THE UNIT MUST BE TESTED AFTER THE INSTALLATION, BY THE END USER, TO ASSURE THAT THE DOOR
CLOSER UNITS FUNCTION PROPERLY WHEN THE ALARM SYSTEM IS ACTIVATED. THE ENTIRE SYSTEM MUST ALSO BE
TESTED PERIODICALLY AFTER THE INITIAL INSTALLATION TEST, IN CONJUNCTION WITH THE TESTING OF THE FIRE
ALARM SYSTEM. THE END USER IS ALSO RESPONSIBLE FOR THE ADJUSTMENTS AND MAINTENANCE TO RETAIN THE
SYSTEM IN WORKING ORDER.
5.3 Unit testing
NORMAL:
The closer unit’s solenoid will be
energized across a normally closed
alarm contact from 24VDC, 24VAC
or 120VAC power supply based on
unit voltage.
FIRE ALARM: When the alarm sounds, the alarm
contact will open and interrupt
current to the solenoid which
releases the hold open allowing the
door to close and latch.
ELECTRICAL SPECIFICATION:
Voltage input - 24VDC + 10% - 15%
24VAC + 10% - 15%
Maximum input current - 24VDC 166mA
24VAC 166mA
