DRY CONTACTS MANUAL
1) INPUT DESCRIPTION
The lock has three digital input (active low) to open it controllable by shorting the pins to GND with a dry contact.
If an open collector device is used, make sure the polarity is correct (i.e. collector/drain connected to IN –
emitter/source connected to GND)
IN1 = open the lock
IN2 = close the lock
IN3 = open followed by an automatic closure
The input signal must be a pulse.
1.a) HOW TO OPEN THE LOCK
Send a pulse (duration from 500 to 1500 ms) to the IN input you will get the full opening of the lock (latches and latch
bolt). The closing will take place automatically when you close the door.
2) OUTPUT DESCRIPTION
Five digital outputs of the type "open collector" provide the following information:
OUT1 : state latch bolt => (OPEN = outside ; CLOSE = inside)
OUT2 : state latches => (OPEN = not outside ; CLOSE = outside)
OUT3 : state door => (OPEN = open ; CLOSE = close )
OUT4 : error => (OPEN = all is OK ; CLOSE = error )
OUT5 : battery status => (OPEN = charged ; CLOSE = low)
Each output is TTL compatible (5V dc) and must comply with the following electrical requirements:
ABSOLUTE MAXIMUM RATINGS
Io sink max. <= 20 mAdc
Vo open max. <= 6 Vdc
Vo saturation max. <= 0,8 Vdc
These outputs are available only when the lock is awake, otherwise they are all "open" (N.O.) to reduce
consumption of energy.
To wake up the lock without opening it, piloting the input IN with a short pulse duration from 50 to 100 msec., the
status will be available immediately after the pulse, and the lock will remain awake for an additional 3 sec. (TIMEOUT
period).
N.B.: The times indicated in charts are only for examples.
Input signal IN (continuous line = 50 ms ; dashed line = 100 ms)
