Section 4 – Basic Hardwired Zones

Remote Keyswitch (Zone 7)

An optional remote 4146 keyswitch for remote arming and disarming of the system can be

installed in this system. Included here are instructions for connecting the keyswitch, the

necessary programming required, plus a description of how the keyswitch operates in the

system.

The remote 4146 keyswitch (with red and green LEDs to indicate status) is connected to

zone 7.

Remote Keyswitch Connections

Connect the 4146 keyswitch's normally open momentary switch to zone 7 terminals (18

and 19). Remove the 2000 ohm EOL resistor if connected across zone 7 terminals.

When zone 7 is used for keyswitch usage, zone 7 is no longer available for use as a protective

zone.

2. Connect the Red and Green LEDs to pins 7, 8, and 9 on the 9-pin connector, using a

4142TR cable as shown in the diagrams on the next page. Note that Figure 11 shows

wiring when using a 4300 Interface Transformer, and that Figure 12 shows wiring when

not using the 4300 transformer.

3. Connect a 2000 ohm EOL resistor across the momentary switch.

4. You can wire an optional closed-circuit tamper switch (model 112) in series with the zone.

If the switchplate is then removed from the wall, the tamper will open, disabling

keyswitch operation until the system is next disarmed from the keypad.

If the tamper (or zone 7 loop wires) is opened when the system is armed, an alarm will

occur.

If you are using more than one keyswitch, connect the EOLR at the last switch. The momentary

arming switches must all be across the loop and the tamper switches in series with it. The LEDs

will not be as bright since they will be sharing drive current in this case.

The 4146 keyswitch can be used with only the Red and Green LEDs connected (omitting the

lock switch and tamper switch) to simply provide an arming/ready status indicator panel (see

“LED Indications” table under

Keyswitch Operation

at the end of this section). When so used,

no connections are made to zone 7, which may then be used as a hardwired protection zone,

provided you do not enable field
