Sentinel-Prox MR-1824 and MR-1824MC Readers

Reader Description

The Sentinel-Prox MR-1824 Reader is a medium-range radio-frequency proximity reader for Gate Control and
Access Control Systems. The Reader consists of a transmit/receive antenna and reader electronics in a
polycarbonate housing. The reader electronics are potted with epoxy resin to protect against the environment.
MR-1824 may be mounted on any non-metallic surface.

Installation Procedure

1. Position the reader (item b in the Parts List) at the desired location. Observe ADA height requirements. Drill four holes
for the screws or anchors, and drill one clearance hole for the cable (see Figure 1).
the size of mounting holes and cable clearance hole.
2. Clip off the white 10-pin connector from the end of the reader's cable. Keep the wires as long as possible.
3. Use a linear regulated DC power supply, between 5 volts (current rating at least 400 milliamperes) and 12.0 volts
maximum (current rating at least 1 ampere). Do not power the MR-1824 from the reader port's DC voltage terminals
on the panel – use a separate DC power supply. (For guaranteed performance, AWID offers P/N PS12-1A power
module.) Tie the ground side of all DC circuits together – including the reader, the panel's reader input port,
the separate DC power supply, and the door or gate release.
4. Connect the reader's wires for ground, data-0, data-1, LED, and power, and the silver drain wire (see Figure 2).
Connect the yellow wire only if used for Beeper control by the panel. Connect the blue wire only if used for
Hold control by the panel. Do not connect the orange and violet wires. Tape or cap the unused wires separately.
5. To install the reader's cable through the wall directly behind the reader, insert both cable slot plugs (item f in
the Parts List) in the sides of the reader's top cover. To run the cable exiting from the side of the reader, press
the cable into the curved channel and guide the cable out of the desired side of the reader. Then insert the cable
slot plug in the other side of the top cover. Extend the cable straight away from the reader housing as far as possible.
6. Install the reader on the mounting surface, using screws (item c in the Parts List) and anchors (item d) as necessary.
7. Apply DC power to the reader. The LED is steady amber. (The beeper does not sound.)
8. Present any AWID proximity credential (card, keytag or wafer) briefly to the reader.
a Long-Short-Short sequence. The LED is steady red to indicate Standby mode. The reader is now initialized and
can read cards. Note: All credentials must be AWID's products. Cards and tags from other companies will not read.
9. The LED color in Standby mode may be changed from red to green, or from green to red, using a Color Changer card,
available from AWID. Remove power from the reader for about 5 seconds, then restore power. While the LED
is amber, present the Color Changer card to change the LED's Standby color. When the color changes, remove the card.
10. When installation is complete and the reader has been tested, insert screw-hole plugs (item e in the Parts List)
into the screw clearance holes to conceal the screw heads. Note: Screw-hole plugs are for one-time use. After they are
seated, they cannot be removed without damaging the plugs.
