Functions
1. Delayed Impulse Inhibit - prevents the door opening on a delayed impulse if 3 is grounded to terminal 4.
2. Locking Circuit - prevents the door from opening if the circuit is open.
For example, use a locking circuit microswitch.
3. Non Delayed Impulse - the door opens immediately on an impulse. The contacts of an impulse device must be
potentially free and have a normally open function.
4. Delayed Impulse - the door opens after preset delay (0 - 15 sec).
5. Safety Sensor - the sensor’s output relay must be voltage free with contacts normally closed. The safety circuit
has a closed-circuit control. Connect the 1000 ohm resistance on the block terminal. The total resistance of the
safety sensor wiring must not exceed 100 ohms when the switch is closed. The safety sensor stops a door
which is about to open if an obstacle is detected in the detection zone. See Control Point 27.
6. Lock Control Relay - contact ratings:
Max power: 0.8A, 30V resistive, 0.3A, 30V inductive
The relay reacts to an opening impulse. For relay hold time adjustment, see Control Point 22.
7. 12 and 24V DC Outputs - The Control Unit includes a 12 or 24 VDC regulated power supply with.
Max current: 24VDC 0.8 A or 12VDC 0. 5 A.
Power Failure In Fire Alarm Mode
If there is a power failure, the Door Operator reverts to battery conservation mode. The Operator is activated when
door is opened manually, and closes at a reduced speed after a preset delay. If the door is open when the failure
occurs, the door Operator closes it.
NOTE: When the power failure ends, the Door Operator remains in the low-energy state.
One manual opening is required to re-energize the Operator to the mode currently selected by the function switch.
Fire Adapter
A Fire Adapter sends a signal to a remote location indicating a power failure or low battery condition. The adapter is
required to meet UL requirements.
