5.3 Connecting to Door Lock
The ICS-KP14 has two isolated volt-free changeover contacts which may be used to release electric
door locks. The contacts are rated at 6A resistive load. Each contact is normally sufficient for two
magnetic door locks. Note that magnetic door locks must be fitted with suppression diodes and must
be connected the right way round. Magnetic door locks supplied by Lasermet have the diode built in.
The contacts are available on the terminals labelled COM, NO, NC on terminal block J5 inside the
keypad. This terminal block is fixed to the circuit board and does not unplug.
Usually only one contact is needed. The positive feed to the door lock should be connected to one of
the COM terminals on J5, and the adjacent NC terminal should then go to the positive connection of
the lock, see below. This will enable the keypad to break the circuit to the lock thus releasing it. For
safety reasons emergency break glass buttons should be provided on both sides of the door to allow
it to be unlocked in the event of an emergency.
Refer to the ICS Manual for more information on wiring door locks to the system.
If no lock is provided this part of the circuit may be omitted, and the keypad should be programmed
not to activate the door relay and ‘Door Unlocked’ indication as described later in this manual.
5.4 Connecting two or more Keypads to one ICS
If it is desired to be able to access the controlled area through more than one door while the laser is
on, additional keypads may be connected as required.
To do this, wire each keypad according to the appropriate wiring diagram above. At the keypad
connector in the ICS, connect all the incoming keypad wires together into the same terminals.
