How to Install Reader and Field Devices

This section summarizes the installation requirements for readers, door strikes and magnetic
locks, door contacts, request-to-exit devices, and miscellaneous alarm devices.
The following readers and field devices have been verified by UL for compatibility with the
controller:
Before mounting or wiring any hardware, be sure to read and understand the manufacturer's
documentation provided with each piece of equipment.
Also, be sure to use wire types and installation practices in full compliance with all applicable
codes, and in conformance with all requirements of local jurisdictional authorities.

VERY IMPORTANT You must install a back-biased suppression diode across the coil of all DC
powered door strikes and magnetic locks. The diode provides protection against the back-
emf that is generated when a strike/lock coil is de-energized. Refer to the door-wiring dia-
gram for additional details.

Mount and wire readers in accordance with the manufacturer's instruction provided with
the readers.
When mounting a reader on a metal mullion or metal junction box, the screws provided
with the reader must be used. When mounting the reader on any other surface, use
appropriate fasteners.
The shield drain wire from the reader cable should be spliced to the shield conductor of
the reader cable coming from the Access Easy Controller. The cables shield must be left
floating at the controller end. This configuration provides the best shielding from exter-
nal interference, and minimizes the likelihood of reader generated interference.
Mount and wire door strikes and/or electric locks.
Wire in accordance with manufacturer's instructions.
The door strike relays on the Access Easy Controller 4-reader control cards are designed
to handle 1A@ 24 VDC Resistive. This should satisfy most door strikes and magnetic
locks. Should larger current locks or strikes need to be controlled, then external inter-
face relays must be installed. External interface relay should also be used with all AC-
powered door strikes.
