TEST PROCEDURES

TO BE PERFORMED BY FACTORY AUTHORIZED PERSONNEL
ONLY! CLEAR FIRE DOOR OPENING AND PROHIBIT TRAFFIC
THROUGH DOOR OPENING WHILE TESTING!

Testing does not affect normal operation of alarm system when
connected to release device/control panel. Testing of the release
device is independent of, and shall in no way be interpreted as an
alternative method of, testing of a central fire alarm system,
motorized operator and/or any other system component employed
on the fire door or counter fire door installation. Complete testing
and normal operation can only be accomplished with power
applied to unit. 

Door must be in open position with power applied to unit to begin
testing. The following procedures describe testing of all options.
Verify options ordered and installed with unit. All tests may not
apply. Refer to Figure 13 for location of all the LEDs and switches
mentioned in this section.

INITIAL POWER UP

1. Connect black battery wire to the black terminal on the

battery. Connect the red battery wire to the red terminal.

2. Apply line power to the unit.

3. Power LED (red) and battery LED (green) will be lit on the

bottom of the release device (Figure 13).

MECHANICAL RELEASE

1. Depress and continue to hold test button on side of release

device. Unit will beep as delay expires. After the selected
delay expires, the device will release the end link and allow
door to drop. Release test button.

2. Reset the door per door manufacturer’s instructions. Raise

door and then reset the release device by pushing downward
on the mechanical reset button at the top of the device. Fully
insert the end link through the side opening on the device
and release the reset button in order to latch end link.

CLOSE DOOR DETECTION (OPTIONAL)

1. Using the chain hoist or motor operator, lower the door to

fully closed position.

2. Verify that Release Disabled LED (yellow) is lit indicating

door closure. Depress and continue to hold test button on
side of release device for 10 seconds. Close Door Detection
logic will prohibit the release device from energizing and
releasing the end link. Reset the test button (Figure 13).

3. Raise door to fully open position.

SUSPENSION OF POWER

1. Make sure door is in fully open position. Turn off all power

to release device and disconnect battery. Immediately upon
loss of power (line voltage and battery backup) to the
release device, a mechanical release will be initiated.

2. Reset the door per door manufacturer’s instructions. Raise

the door and then reset the release device by pushing
downward on the Mechanical Reset Plunger at the top of the
device. Fully insert the end link through the side opening on
the device and release the Mechanical Reset Plunger in
order to latch end link. Press the “Reset” button on the
device to reset the alarm loop.

To prevent possible SERIOUS INJURY or DEATH:
• Clear fire door opening and prohibit ALL traffic through door

opening while testing.

• Test every 90 days to assure proper operation of release

device.
