Linear 212w User Manual
212w Wiring Diagrams and Specifications
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.
IEI recommends using a filtered 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
