Installation Instructions

This kit converts all 33/35A and 98/99 series mechanical exit devices to quiet electric latch (QEL) retraction devices.
This kit can also be used for motor replacement on existing QEL devices.
Install according to instructions or device will not function and panic or fire label will be void.
The QEL wiring must be attached to the fire alarm system if installed on fire exit hardware.
If existing device is fire rated or less dogging a QEL baseplate conversion kit is required.

Check Operation

A.

Activate each input and verify all QEL devices operate properly.

B.

If any device does not operate properly, see step 16 for troubleshooting.

QEL Response
LED - Solid green
Latchbolt - retracted

Operation normal, latch retracted immediately

LED - Solid red after latchbolt
attempts to retract multiple times

Verify mechanical adjustment (on vertical rod or mortise lock devices
if used). Remove and reapply input voltage to reset this condition.*

Condition/Solution

Latchbolt cannot fully retract mechanically

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

LED- Flashing red

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.
No input voltage
Problem with the power supply, control switch or wiring
No input voltage
Mechanical dogging is engaged

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).

2. Depress pushbar. Door should begin to open with pushbar
depressed halfway.
