TEST RELEASE DEVICE AND DOOR OPERATOR
AUTOMATIC DOOR CLOSURE TESTS (CONTINUED)
(MOTORIZED DOORS ONLY)
Three-Cycle Obstruction Test
1. With the door fully open, place an obstruction no less than
12" in height in the normal path of the door.
2. Depress and continue to hold the test button of release device
through step 4. Optional annunciator will turn on indicating a
door closure is about to occur. After the preset delay the door
will begin to close.
3. Upon contact with the suitable obstruction being utilized, the
safety edge will reverse the operator raising the door to the
open position. The release device will make three attempts to
close through the operator. The release device will turn off the
operator when the door reaches the open position and
releases the door mechanically through the drop release
mechanism. NOTE: The release device can optionally be set to
stop the door on the obstruction after the third triggering of
the safety edge (see DIP switch options). The door will stop
on the obstruction and will close fully after the obstruction is
removed. The annunciator will continue to sound until the
alarm condition has been cleared.
4. Release test button. The test is complete.
5. Reset the fire door per manufacturer’s instructions.
6. Reset release device by pushing in and holding the
mechanical reset plunger. Insert end link through enclosure
opening and release reset plunger latching the end link.
7. Depress Open button on operator control raising door to open
position.
Wall Mounted Test / Reset Switch (provided)
This test disables the internal counter circuit and allows the door
to continuously cycle if a suitable obstruction is utilized (refer to
Three –Cycle Obstruction Test.)
1. Clear fire door opening and prohibit traffic through door
opening while testing.
2. Insert key into wall mounted Test / Reset switch, turn key and
hold in direction of test indicator until test is complete.
Annunciator will turn on and the door will begin to close after
preset delay. If no obstruction is placed in the path of the
closing door, the door will fully close and the motor will turn
off. If an obstruction is encountered, the door will close until
it strikes the obstruction and reverse to a fully open position.
The door will immediately begin to close again and continue
this cycle until the key is returned to the off position.
3. Return Test / Reset switch to off position to silence the
annunciator. The door will re-open if Auto-Open feature is
enabled, see DIP Switch Configuration Setting.
