TOOLS NEEDED
The QEL94/9547 Exit Device is designed to provide reduced pushpad projection and a unique appearance b
y embedding
the device into the face of the door.
These instructions assume that a factory-prepared door and frame are being used.
Before starting installation, review "Warnings," "Parts," "Specifications," and "Tools Needed."
Mechanical
•Vertical rods adjustable for doors 6'8" to 8' tall

Electrical Load
•Voltage: 1.4 A inrush (0.5 sec)
•Current: 0.14 A holding

approximately 38¹⁄₂”. Top rod sections are longer than bottom rod sections.
b. Attach brackets to top latch, then thread rod assembly onto latch (Figure 6-2).
c. Slide rod and latch into prep at door top (Figure 6-3), and attach rod to center case (Figure 6-4).

11 ADJUST TOP ROD
a. Fully depress and hold pushpad.
b. Set top latch in fully retracted (hold) position (Figure
11-1).
c. Push down on center case connector, adjust rod
length, and connect top rod (Figure 11-2).
d. Verify that pushpad projection, when depressed,
is between 1¹⁄₈” and 1¹⁄₄”. Adjust top rod if necessary:
Lengthening the top rod will reduce pushpad
projection when depressed.
e. If using trim, verify that the trim fully retracts the top
latch. If the trim does not fully retract the top latch,
adjust the top rod so it is shorter.
f. Open door and release latches by inserting a
Phillips head screwdriver into the ratchet release
plunger hole. Check top latch deadlocking: Top latch
should not retract when pressed down.
•If top latch bolt does not stay fully retracted,
shorten top rod (Figure 11-2) and retest.
•If top latch bolt does not fully extend or deadlock,
lengthen top rod (Figure 11-2) and retest.
•If bottom latch bolt does not stay fully retracted,
shorten bottom rod (see Step 12) and retest.
•If bottom latch bolt does not fully extend, lengthen
bottom rod (see Step 12) and retest.

3. The QEL is compatible with an existing 900-2Q board
if currently installed.
5. Latchbolt retraction of (2) sequenced QEL’s requires
more than 1 second to complete.
6. For double door QEL applications with auto
operators, it is recommended to use a PS904, 906, or
914 power supply.
4. When powering (2) QEL’s with a PS902, both cannot
be activated at the same time, they must be
sequenced.
2. If installing board in location 2 or 3, rotate board 180˚

17 APPLY POWER TO POWER SUPPLY. IF 900-BB IS USED, THEN RECONNECT BATTERIES
18 CHECK OPERATION
a. Activate each input and verify all QEL devices operate properly.
NOTE: During the first activation, each device will perform a one time self calibration, which is normal. For best results, power
each device separately so that the calibration cycles do not overlap.
b. If any device does not operate properly, see step 19 for troubleshooting.

Improper mechanical adjustment or QEL calibration
First check mechanical adjustment (on vertical rods or mortise lock devices, if used) and correct
adjustments*
Calibrate the QEL
1. Apply power and wait until the LED is solid red
2. Momentarily press the calibrate pushbutton (LED will flash green)
3. QEL will go through a retraction sequence to complete calibration, LED will be solid green and
latchbolt retracted
4. Remove and reapply power to verify correct operation
If the power to the QEL is being controlled by an access control system with momentary unlock, calibrate
as follows:
1. Open door completely if using auto operator
2. Press and hold the QEL pushbutton
3. Activate the access control input to unlock the QEL
4. Immediately after the QEL LED turns on green, release the QEL pushbutton
5. The QEL will calibrate (this will look like a fast then a slow pull)
6. Reapply power to verify correct operation
