QEL 33A/35A,
24908394
Baseplate Conversion Kit Installation Instructions
1. This kit converts all 33/35A and 98/99 series EL devices and re devices built prior to Oct. 2014 to quiet electric latch (QEL) retraction
devices.
2. QELX and HD-QELX Baseplate Conversion Kits are only for use with Von Duprin AX98/99, AXXP98/99, and AX33A/35A exit devices only.
They are not to be used to convert standard exit devices to QELX.
3. Install according to instructions or device will not function and panic or re label will be void.
4. The QEL wiring must be attached to the re alarm system if installed on re exit hardware.

WARNING
If existing exit device is re rated, do not install HD-QEL or HD-QELX
(hex dogging) baseplate. Doing so will void re rating.
1 Disconnect Power
To avoid risk of shock, disconnect AC power from power supply
before proceeding with this conversion. If using Battery Backup
option, unplug all four wires from battery terminals.
2 Detach Vertical Rods if present
Refer to device instructions as needed.
3 Remove Exit Device from Door
Device and trim must be held

3. The QEL is compatible with an existing 900-2Q board
if currently installed.
5. When powering multiple components, verify that the
amperage requirements of all components combined
does not exceed the power supply output rating.
4. Latchbolt retraction of (2) sequenced QEL’s requires
more than 1 second to complete.
2. If installing board in location 2 or 3, rotate board 180˚
Notes: 1. 24VDC output setting required when QEL

QEL Response Condition/Solution
Operation normal, latch retracted immediately
Latchbolt cannot fully retract mechanically
Verify mechanical adjustment (on vertical rod or mortise lock devices
if used). Remove and reapply input voltage to reset this condition.*
See Check Mechanical Operation on page 8 as needed.**
Excessive tamper (while power applied, the pushpad was pulled out
at least 3 time)
Wait 15 seconds and latchbolt will retract again OR remove and
reapply power to clear condition
Voltage low during latchbolt retraction (latchbolt retracts at reduced
force)
Wire length is too long, wire gauge is too small or power supply has
poor regulation
Input voltage is too high for proper operation
Wrong power supply, power supply defective.
Input voltage is too low for proper operation
Wrong power supply, power supply defective or not set to the proper
output voltage.
To set, remove AC power from power supply, change power supply
setting from 12 to 24VDC, then reapply AC power and verify proper
operation.

1. Make sure device is not dogged for SD-QEL / HD-QEL.
2. Depress pushbar and make sure latch bolt retracts and extends
fully (see Figure 1).
3. If latch bolt does not retract or extend fully, adjustments may be
required per the device installation instructions.

1. Make sure device is not dogged for SD-QEL/HD-QEL.
2. Depress pushbar. Door should begin to open with pushbar
depressed halfway.
3. Close door. Top latch should be secure. If two point latch, bottom
latch should be secure as well.
4. If device does not function as described in steps 2 and 3,
adjustments may be required per the device installation
instructions.
Any HD Device
1. Fully depress pushbar.
2. Insert hex dogging key and turn clockwise.
3. Release pushbar and verify latchbolt remains retracted.
4. Fully depress pushbar.
5. Insert hex dogging key and turn counter clockwise.
6. Release pushbar and verify latchbolt extends fully.
