Lock Controller Output Connections
1
0v: Connect to PSU 0v - ONLY CONNECT IF SYSTEM NOT OEM PRE-WIRED.
2
0v: Used for input triggers.
3
0v: Used for input triggers.
4
0v to Lock: Switched 0v from the lock – energises the lock when switched on.
5
12v to lock: Constant.
6
From OVR: +12v from Emergency lock over-ride switch (usually fitted with metal loop).
7
To OVR: +12v to Emergency lock over-ride switch.
8
+12v: Local power supply input 12v - ONLY CONNECT IF SYSTEM NOT OEM PRE-WIRED
Note: Thermal fuse (across 7/8) provides protection for the board.
The powered output features transistor-based switching of lock power. If testing using a
multi-meter a minimum current sink of 50ma is required to correctly read a voltage drop
when the output is triggered.
Test procedure
Have suitable load wired across terminals 4 & 5. Ensure lock mode switch is set to EN
and orange LED is lit. LED will go out if mode switch set to DE-EN. Set multi-meter to
DC volts, measure across terminals 4 & 5, if NO voltage is read check terminals 6 & 7
for metal loop, tighten if required.
If Lock is connected and powered but does not drop when triggered, i.e. orange LED
goes out and tone is heard, check for shorts from Lock to 0v/ground. Remember Lock
Controller switches 0v NOT 12v!
Common issues with lock not de-energising are due to Local lock picking up 0v from
door frame/conduit etc.
