This section provides information regarding the use of expansion modules for

expanding the number of wired zones in the system, the modules that can be

used and their wiring connections, plus a procedure for programming the

wired expansion zones.

Installing Zone Expansion Units

You can add an additional 8 wired EOLR zones to the basic control’s 8 zones,

for a total of 16 wired zones, by using a No. 4219 Wired Expansion Unit, or

4229 Wired Expansion/Relay Unit.

Connections and Set-Up

o~t+oN

You can mount an expansion unit within the control

cabinet if space permits. Otherwise, mount the unit

outside the cabinet.

Units are supervised against removal. Keypads will

display CHECK and zone 09 if a zone expander is

disconnected.

Units have tamper protection for security when

mounted outside of the cabinet.

Assign zone numbers 10-17 for the eight wired

expansion loops (designated A to H). You can

program these zones individually (in *56 interactive

mode) for Partition 1 or 2. See “programming Wired

Expansion Zones” later in this section.

Connect the 4219 or 4229 module to the control’s keypad terminals (see

diagram below).

Set the 4219 or 4229’s DIP switch for device address “l” (switch 2

“OFF” and switches 3,4,5 “ON”). Switch 1 determines expansion zone As

response time (“ON” = normal response, “OFF” = fast response). For

location of the DIP switch in the unit, see the diagram below (location of

DIP switch for both units is in the same location).

For additional information, see instructions supplied with the 4219 and

4229.
