SR-2400MI-GR-MP
Multi Protocol Proximity Reader
Reader Description
The SR-2400MI-GR-MP Multi Protocol Proximity Reader is a radio-frequency proximity reader for Access
Control Systems. The Reader consists of a transmit/receive antenna and reader electronics, in a polycarbonate
housing. The reader electronics and antenna are potted with epoxy resin to protect against the environment. The
Reader may be mounted on a metal doorframe, a window mullion, or any surface (wall, cabinet, etc.).

(d) Screw-hole plug Qty=3
(1 spare)
Installation Procedure
1. Position the reader (item b in the Parts List) at the desired location. Observe ADA height requirements.
Drill two 7/64 (0.109)-inch holes for the reader screws, and one clearance hole for the cable (see Figure 1).
2. Clip off the white 10-pin in-line connector from the end of the reader’s cable. Keep the wires as long as possible.
3. Connect the reader's ground, Data-0, Data-1, LED and power (see Figure 2). Connect yellow wire only if used for
Beeper control. Do not connect orange, blue & violet wires to anything. Tape or cap all unused wire separately.
4. Use a linear regulated DC power source, between 5 VDC (current rating at least 40 mA) and 12 VDC (at least 70
mA). The power source may be the Ground and Power terminals on the panel's reader port.
5. Align the reader with the screw holes in the doorframe or other surface. Fasten the reader to the doorframe using
supplied screws (item c in the Parts List) or other fasteners.
6. Apply power to the reader. The LED is steady-amber. (The beeper does not sound.)
7. Present any supported proximity credential (card, tag or wafer) briefly to the reader. The beeper sounds, and the
LED changes to steady-red indicating Standby mode. The reader is now initialized and can read cards. Note:
Verify with your local sales representative what cards are supported.
8. The LED color in Standby may be changed from red to green, or from green to red, using a Color Changer card.
Remove power from the reader; disconnect the brown wire from the panel; then restore power. While the LED is
amber, present the Color Changer card to toggle the LED’s Standby color. Reconnect the reader’s brown wire to
the LED (or Green LED) terminal.
9. When installation is complete and the reader has been tested, insert screw-hole plugs (item d 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. Remove power before any wiring change. Connect the reader’s black wire (ground) first, and the red wire (power) last.
2. When the brown and yellow wires are not used, LED and beeper remain active and under the reader's internal control.
3. The LED and Beeper 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. SR-2400MI-GR-MP readers have Wiegand-protocol electrical interface only. (There is no RS-232 interface.)
