Sentinel-Prox MR-1824HiLo Reader
Reader Description
The Sentinel-Prox MR-1824HiLo Reader Set is a air of medium-range radio-frequency roximity readers with
s ecial rogramming that allows them to work as a set at a single installation site, without interference between
the two readers. The readers’ firmware coordinates the duty cycles for the two readers. This revents one
reader from transmitting its signal while the other reader is transmitting to, or receiving a re ly from, an AWID
encoded credential. Reader labels and instructions are s ecial. There is out ut on the Wiegand data lines only.

(a) Installation sheet .........................................................1
(b) MR-1824 Reader ........................................................2
(c) #6-20 x 1.375” self-ta ing screw .............................. 8
(d) Plastic anchor ............................................................. 8
(e) Screw-hole lug......................................... 10 (2 s are)
(f) Cable slot lug............................................................ 4
Installation Procedure for Each Reader
1. Position the first reader (item b in the Parts List) at the desired location. Observe ADA height
requirements. Drill 4 holes for the screws or anchors, and drill 1 clearance hole for the cable (see Figure 1).
The installer determines the size of mounting holes and cable clearance hole.
2. Cli off the white inline connector from the end of the reader’s cable. Kee the wires as long as ossible.
3. Use a linear regulated DC ower su ly, between 5 volts (current rating 800 milliam eres or more)
and 12.0 volts maximum (current rating 2 am eres or more) for the combined readers. Do not power
the MR-1824HiLo from the reader ort’s DC voltage terminals on the anel – use a se arate DC ower
su ly. (For guaranteed erformance, AWID offers P/N PS-123.3A ower module.) Tie the ground side
of all DC circuits together – including both MR-1824 readers, the anel’s reader in ut ort, the se arate
DC ower su ly, and the door lock or gate motor contacts.
4. Connect the reader’s wires for ground, data-0, data-1, LED and ower, and the silver drain wire (see Fig. 2).
Connect the yellow wire only if used for Bee er control by the anel. Connect the orange and violet wires
to the o osite colors (violet and orange) on the other reader of the set. Do not connect the blue wire.
Tape or cap the unused wires se arately. The MR-1824HiLo set uses a single Wiegand in ut on the anel.
5. To install the reader’s cable through the wall directly behind the reader, insert both cable slot lugs
(item f in the Parts List) in the sides of the reader’s to cover. To run the cable exiting from the side of the
reader, ress the cable into the curved channel and guide the cable out of the desired side of the reader.
Then insert the cable slot lug in the other side of the to cover. Extend the cable straight away from
the reader housing as far as ossible.
6. Install the reader on the mounting surface, using screws (item c in the Parts List) and anchors (item d)
as necessary.
7. Re eat ste s 1 through 6 for the second reader of the MR-1824HiLo set. Readers may be u to 75 ft a art.
8. A ly DC ower to both readers. The LED is steady amber. (The bee er does not sound.)
9. Present any AWID roximity credential (card, keytag or wafer) briefly to the reader. The bee er sounds a
single Long bee . 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 roducts. Other com anies’ cards and tags will not read.
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 ower from the reader for a few seconds, and then
restore ower. While the LED is amber, resent the Color Changer card to toggle the LED color at Standby.
When the LED color changes, remove the card.
11. When installation is com lete and the readers have been tested, insert screw-hole lugs (item e in
the Parts List) into the screw clearance holes to conceal the screw heads. Note: Screw-hole lugs are
for one-time use. After they are seated, they cannot be removed without damaging the lugs.

Product Specifications
Material of Mounting Surface ... Non-metallic material only (Kee readers at least 3 or 4 inches from all metal.)
Note: If a reader must be mounted on a metal surface, use the metal-com ensated MR-1824HiLoMC set.
Cable to Controller
• 4 to 6 conductors (not twisted airs), stranded, 18 AWG, color-coded insulation, overall 100% shielded
Note: (a) Wire may be 22 gauge for data & control lines if DC ower is run in a se arate shielded 18 gauge cable.
(b) Number of conductors de ends u on use of o tional features – LED and Bee er. See Figure 2.
• Length for Wiegand Interface ...............U to 500 feet
Read Range (Ty ical for AWID’s CS-AWID clamshell cards)
• At 5 VDC ..............................................About 12 inches (30 cm)
• At 12 VDC ............................................18 to 24 inches (45 to 60 cm)
Note: Read range varies, de ending u on the tags used and local conditions.
Characteristics
• Indoor and Outdoor ...............................Rated for outdoor installation
• O erating Tem erature .........................-35° C to 65° C (-31° F to 150° F)
• O erating Humidity...............................0 to 95% non-condensing
O erating Parameters
• Current drain for each reader in set.......250 mA eak at 5 volts .............. 600 mA eak at 12 volts
• Excitation Frequency.............................125 kHz
• Wiegand Out ut ....................................26 bits to 50 bits (as rogrammed in the cards or tags)

Notes
1. For suggestions on best erformance, read AWID’s memo “MR-1824 – Assuring Maximum Read Range”.
2. When the yellow wire is not used, the bee er remains active and under the reader’s internal control.
3. The LED and Bee er lines are logic levels. Never a ly ower to them. They may be ulled 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-1824HiLo readers have Wiegand- rotocol electrical interface only. (There is no RS-232 interface.)
