Reader Description
The Sentinel-Prox MR-1824 Reader is a medium-range radio-frequency proximity reader for Gate Control and
Access Control Systems.
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

1. Position the reader (item b in the Parts List) at the desired location.
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. Install the ferrite clamp (Parts List item g) on the +DC power, DC ground, and drain wires. See instructions on page 3.
6. 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.
7. Install the reader on the mounting surface, using screws (item c) and anchors (item d) as necessary.
8. Power up the reader. The LED should be steady amber. (The beeper does not sound.)
9. 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 can read cards.
Note: All credentials must be AWID's products.
10. 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.
11. 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.
