OPTIONAL KEYSWITCH
A keyswitch can be installed in the RE-1 Entry System to provide
keyed access. The RE-1 case is designed to accept a Medco Model
KS-M keyswitch.
Keyswitch Installation
1. Disconnect the wiring harness connector and remove the antenna
terminal block. Remove the four circuit board retaining screws and the
RE-1 circuit board (see Figure 16).
2. Remove the screw and washer that retain the keyswitch hole access
plate (see Figure 17).
3. Hold the lock cover and plastic spacer in place on the RE-1 case.
Secure the assembly with four screws, lock washers, and nuts. Slide
the keyswitch into the hole, oriented as shown (see Figure 18).
Secure the keyswitch with the large switch nut. Use bolt cutters to trim
the two screws closest to the case edge so they will clear the circuit
board (see Figure 19).
4. Plug the two keyswitch snap-on wire leads (supplied with the switch)
onto the keyswitch COM and N.O. pins (see Figure 19).
5. Replace the RE-1 circuit board. Secure the board with the four
screws. Reconnect the antenna terminal block and wiring harness
connector.
6. Connect one keyswitch wire to the RE-1 OPEN #1 terminal. Connect
the other keyswitch wire to the RE-1 COMMON terminal.
