212w Wiring Diagrams
TECHNICAL NOTES
This product was re-designed using a new manufacturing
technology, which changed the physical appearance of
the keypad electronics. Also, the voltage selection jumper
on the main circuit board is no longer required.
To prevent electrical kick back voltage from damaging the
keypad, when using an electrical locking device, you MUST
install the transorb as close as possible to the lock. Wire the
transorb in parallel with the lock power terminals.
Also, to avoid ESD (electro-static discharge) from interfering
with the operation of the keypad, ground the negative terminal
of the keypad to earth ground. If you cannot ground the power
supply, then you must ground the keypad housing.
The manufacturer recommends using a fi ltered and
regulated power supply.
When mounting the 212w outside, use a weatherproof back
box and apply silicone to the area where the wires enter the
case. Also, provide a weep hole at the bottom of the back box
to prevent condensation from collecting on the circuit board.
This keypad is not for use in extreme weather conditions;
please consult the factory for additional keypad models.
