Reader Configuration Setting and Installation
Find a suitable location to anchor the reader mounting bracket. The mounting of the reader does not
require a junction box. However, rigid conduit is required for outdoor application. A single gang
junction box may used to provide transition to rigid conduit. If a single gang junction box is used, a
wall plate (optional) may be used to cover the junction box. The reader is then secured to the mounting
bracket using a screw. Refer to figures for reader dimensions and typical junction box usage.
Connect door hardware/power according to the configuration selected. Wires of 22AWG or larger are
recommended for field wiring. See local electrical code.
Coat reader connector with the silicone grease supplied to seal out moisture for outdoor mounting.
FOR 24Vac STRIKE, PANASONIC ERZ-C07DK470
MOV SELECTION:
VOLTAGE RATING > Vac RMS
DIODE SELECTION:
DIODE CURRENT RATING > 1X STRIKE CURRENT
DIODE BREAK DOWN VOLTAGE : 4X STRIKE VOLTAGE
DIODE 1N4001 (50V/1A) TYPICAL
To avoid having ESD (electrostatic discharge) interfering with the operation of the reader, the reader casing
shall be grounded. This can be accomplished be tying the mounting bracket to earth ground locally (e.g.
grounded conduit). The reader has a four dip switch block which must be configured. All four switches
must be in the OFF position. When looking into the back of the reader, all switches should be pushed
away.

Relay Contact Protection/Noise Suppression
Load switching can cause contact transfer, welding, and abnormal wear, which can cause premature
contact failure. The switching of an inductive load (strike) can also cause EMI (electromagnetic
interference). To prolong contact life and increase total system reliability, contact protection circuit must
be used. The following two circuits are recommended: For DC application, use a diode circuit; for AC
application, use a MOV (metal oxide varistor) circuit. Locate the protection circuit as close to the load
as possible, as the effectiveness of the circuit will decrease if it is located too far away. As a guideline,
the distance should be within 12 inches (30 cm).
