Access Control /
Control Board
A. If the ‘OPN’ signal is connected to the access control system, verify that the ‘OPN’
signal is not being provided with a continuous dry contact.
B. Press SW6 and swipe a business card clockwise through the optical sensors.
C. If the unit re-locks, the problem lies with the access control system.
D. If the unit does not re-lock, but re-locks after time out, proceed with optical sensors
troubleshooting.

Optical sensors are installed
incorrectly
A. Press SW6 and swipe a business card clockwise through the optical sensors.
B. The green LED on the control board should turn OFF, and the unit should re-lock.
If the unit re-locks, then optical sensors are installed correctly.
C. If the unit does not re-lock, press SW6 again and swipe a business card
counterclockwise through the optical sensors.
D. If the green LED on the control board turns OFF, and the unit re-locks, then the
optical sensors are installed incorrectly.
E. Using a Phillips head screwdriver, remove the optical sensors from the optical
sensor mounting plate and switch the mounting positions. Repeat step A.
NOTE
: The business card must pass through both optical sensors for a correct
reading.

Solenoid plunger is binding
1. Check for and remove any debris from the solenoid plunger and cavity area.
2. Use an alcohol-moistened Q-tip to clean the solenoid plunger. Do not use water or
lubricate the solenoid plunger. The solenoid is designed for dry operation.
