AWID SENTINEL-PROX MR-1824 Assembly instructions

Reader Description Revision E July 21, 2006
TheSentinel-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. MR-1824-MC is a metal-compensated version of this
reader for mounting on or near a metal surface; see the attached sheet for notes on installing MR-1824-MC.

Installation Procedure (Installation notes for MR-1824-MC are on attached sheet.)
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 installer
determines 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. Connect the reader’s cable to the controller panel as shown in 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 to anything. Tape or cap all unused wires singly.
4. Use a linear regulated DC power supply, between 5 volts (250 mA) and 12.0 volts maximum (600 mA peak).
Do not power the MR-1824 from the panel’s internal power supply –use an external DC power supply.
For guaranteed performance, order P/N PS12-1A from AWID. Tie the ground side of all DC circuits together –
including the reader, the panel’s reader input port, the external power supply, and the door or gate release.
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-fit 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.
6. Install the reader on the mounting surface, using screws (item c) and anchors (item d) as necessary.
7. Power up the reader. The LED should be steady amber. (The beeper does not sound.)
8. Present a valid AWID proximity credential (card, keytag or wafer) briefly to the reader. The beeper sounds a single
Short beep. The LED is steady red to indicate Standby mode. The reader is now initialized and prepared to read
cards. Note: All credentials must be AWID’s products.
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 a few seconds, then restore power. While the LED
is amber, present the Color Changer card to toggle the LED’s Standby color.
10. When installation is complete, 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.

Notes
1. For suggestions on best performance, read AWID’s memo “MR-1824 – Achieving Maximum Read Range”.
2. When the yellow wire is not used, the beeper remains active and under the reader’s internal control.
3. Beeper, Hold, and LED lines are logic levels. Never apply power to them. They may be pulled to a low level
(0 to 1.2 VDC) to enable their function, and left floating at a high level (3.6 to 5.0 VDC) when not used.
4. MR-1824 and MR-1824-MC readers have both Wiegand-protocol and RS-232 interfaces. For information on RS-232,
contact AWID’s technical support.
5. For additional information, please see AWID’s web site ( www.awid.com). Send all technical support questions

Notesfor MR-1824-MC
· Use MR-1824-MC, the metal-compensated version of the MR-1824 reader, when mounting
readers on a metal surface. Nearby metal will cause the electromagnetic field around the
MR-1824 reader to collapse. MR-1824-MC will sustain the field, but at a reduced strength.
· Follow the steps below in place of steps 1-4 on page 1 of the Installation Sheet for MR-1824.
Installation Procedure
1. To mount the MR-1824-MC reader on the metal surface:
a. Remove the 4 screws through the front of the reader’s plastic housing. This reveals the reader
body with 4 mounting holes, aligned to the center holes of the 4 ferrite tiles.
b. Use the ferrite tiles as templates for mounting holes on the metal surface. These holes are at
the center of each 4” X 4” tile. The center of the hole is 2” from each edge.
c. If necessary, enlarge the hole in the ferrite tiles slightly by drilling or reaming.
d. Screw the reader’s plastic base and the ferrite tiles to the wall by inserting the 4 screws (item c
in the Parts List) first through the inside of the plastic base, then through the holes in the ferrite
tiles, then into the mounting holes in the wall.
e. Re-attach the reader’s plastic cover using the screws that were removed in step 1.a.
2. Clip off the white 10-pin connector from the end of the reader’s cable. Keep the wires as long
as possible.
3. Connect the reader’s cable to the controller panel as shown in 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 connectthe orange and violet wires to anything.
Tape or cap all unused wires singly.
4. Use a linear regulated DC power supply, between 5 volts (170 mA) and 12.0 volts maximum
(350 mA).
Do not power the MR-1824-MC from the panel’s internal power supply – use an external
DC power supply.
For guaranteed performance, order P/N PS12-1A from AWID.
Tie the ground side of all DC circuitstogether – including the reader, the panel’s reader input
port, the external DC power supply, and the door or gate release.
Continue with “Installation Procedure” at step 5on page 1.
