GE Contactless Medium Read-Range Reader Model 260 15
Installation Notes (unless otherwise specified).
All numbered items below are referenced on the appropriate wiring diagrams
that follow.
1. Fuse, power supply, door s trike, prote ction device, an d relay are provided b y
the installer.
2. The 470 included Ω ½-watt resistor, must be installed at the Micro/5 2RP
terminal block. The Micro PX-2000/PXN-2000 and Micro/5 2RP and 8RP
boards do not require this resistor.
3. Shielded cable is recommended in electrically noisy environments.
4. If using shielded cable: At the reader end: connect all shie lds together and
insulate them. At the Micro end: connect the shield to th e mic ro ca b ine t as
indicated in the appropriate Micro Installation Manual.
5. If using a local power supply, do not connect the power (8-30 VDC) line from
the microcontroller to the reader. The ground line of the power supply must
be connected to the micro (pin 2 on the reader connector).
6. J3 is typically not used in this installation. See Figure 13, “GE Model 260
Reader to Micro/Reader Junction Box and Microcontroller,” on page 22.
7. Blocking diodes may be 1N414 8 or equivalent (installer supplied) and located
in a secure area.
8. Protection diodes may be 1N4002, 1N40 03, or 1N4004 (installer sup p lied) for
the door strike assembly.
9. Install two 1k Ω ¼-watt resistors (installer-supplied) at Door DI and Exit DI,
as shown.
10. Connect a protection device across the door strike.
AC Door Strikes: Connect an MOV (metal oxide varistor) across the door
strike. (Incl uded with Micro/5 2RP, 8RP, and PX(N)-2000).
DC Door Strikes: Connect a diode ac ross th e door strike (cathode to posit iv e
side of door strike). (Included with Micro/5 2RP, 8RP, and PX(N)-2000).
11. Relay Coil Current Restriction (Micro/5 2RP with external relay).
The relay coil current must be limited to 40 mA to prevent damage to the
board. Verify that the relay coil requires less than 40 mA.
12 VDC relay: coil resistance must be greater than 300 Ω.
The Micro/5 2RP with internal or AUX DO relay current through the relay
contacts must be limited to less than 2 A to prevent damage to the 2RP.
Current limiting may be achieved by using either a current-limiting power
supply or by wiring in an external fuse.
12. Connect protection diode across relay coil. Connect a diode across the relay
coil (cathode to positive side of relay coil).
General not e: Pair wires as shown in all wirin g diagr ams.
