NOTE:
1. For inductive loads such as electric strikes and
electromagnetic locks, the enclosed
varistor
must be connected in parallel with the load, at
the load terminals and not in the keypad.
2. Ensure power supply is of correct rating, taking
into account the current requirements of the
locking items and accessories.
3. The interior switch input is via a dry contact
between the White & Orange wires. The door
strike will activate for the time programmed into
the system. This input is disabled during
programming and latch mode.

TESTING THE KEYPAD
Apply power to the keypad:
The keypad’s buzzer will sound briefly, the red LED will
illuminate briefly. Initialisation is now complete, with a
default master code of 1-2-3-4 and 5-second open door.
Enter the master code: [1 2 3 4 #]:
The Door Relay changes its contacts for 5 sec. The
Green LED will light up for 5 seconds.
Repeat this step 2 or 3 times.
If the master code is entered incorrectly, the Red LED
illuminates for 3 seconds.
Re-enter the Code as soon as the Red LED goes OFF.
PROGRAMMING THE KEYPAD
Enter **1 2 3 4**
The keypad enters programming mode, the red LED
flashes.
If no further information is added, the unit will revert to
normal operation after a 15 second delay.
To exit programming press #
There are six programming options:
1. Set new master code
2. Set new user code
3. Erase a user code
4. Erase all user codes
5. Set door open time (1-99 seconds)
6. Set output to latch option
Do not insert security plugs into fixing
holes until all installation and testing has
been completed!! These items require
drilling out and cannot be re-fitted.
It is good practice to change the factory
default master code. There is no way to
recover the new Master Code, if it is lost or
forgotten however, the unit can be easily reset
to Factory Presets and re-programmed again.
