Revision E 

July 21, 2006

 

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.  

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.
