Connect the Red and Green LEDs to pins 7, 8, and 9 on the 9-pin
connector, using a 4142TR cable as shown in Figures 17 (A) and (B).
Connect a 2000 ohm EOL resistor across the momentary switch.
You can wire an optional closed-circuit tamper switch (model 112) in
series with the zone: If the switchplate is then-removed fi-om the wall, the
tamper will open, disabling keyswitch operation until the system is next
disarmed fi-om the keypad.
If the tamper (or zone 7 loop wires) is opened when the system is armed, an
alarm will occur.
