Product Description
The Elpas Proximity BUS Reader is a 125KHz, EM4100
compatible; indoor/outdoor surface mounted proximity reader.
The reader features low power consumption, high reliability, and
consistent read ranges (up to 10cm /4 inches), regardless of card
or tag.
Designed for indoor/outdoor environments, the reader’s solid
state electronics is housed in an epoxy potted, (IP-67 rated), of
thermoplastic casing that ensures years of maintenance free
deployments.
The Proximity BUS Reader contains an onboard I/O that enables
the monitoring of one alarm sensor and control of one digital
open-collector output. The proximity reader also includes a
2m/6.5ft long RS-485 power/data cable for interfacing to a Elpas
BUS Master (a RF IP Reader or an ELC Controller) via a RS-485
Junction Box (P/N:5-JBA00485).
Note: An Elpas RS-485 BUS may contain up to fifteen Elpas BUS devices
(such as RF or IR Readers, Elpas Display Panels, LF Beacons, or other
Proximity BUS Readers) which are wired together using Elpas RS-485
Junction Boxes.

Mounting Considerations
The Proximity BUS Reader should be wall mounted, adjacent to the
opening side of the door (outside of the protected area), at a height
of approximately 1.2m/4ft above the floor
Note: When installing Proximity BUS Readers on adjacent doors,
make certain that the minimum distance between readers is at least
60cm/2.0ft to ensure proper operation.
Mounting Procedure
1. Insert a screwdriver into the recess at the bottom of the case, and
separate the cover from the reader.
2. Place the base on the installation surface, mark two screw holes,
drill the holes, and insert the supplied plastic anchors, if
necessary.
3. Fasten the base to the mounting surface, using the two #6 Tap
screws supplied with the reader.
4. Replace the reader’s cover, ensuring that the cover is aligned with
the reader. This enables the LED to be visible.
Note: Do not install the Proximity BUS Reader directly onto a metal
surface, since can significantly decrease the effective read range of
the device. If you have to mount the reader onto a metal surface,
insert a RDR-BACK (P/N: 3-6317-0) between the device’s reader
base and the metal surface.
