Burglary Zones

10.1 Description

The XR20/XR40 terminals 12 to 24 are the nine burglary zones. For programming purposes, the zone numbers

are 1 to 9. The zone configurations on terminals 12 to 24 are described below. The XRSuper6 terminals 12 to

18 are the five burglary zones with terminal 16 providing the ground for zone 5.

Terminal Function Terminal Function

12 Zone 1 voltage sensing 19 Ground for zones 5 & 6

13 Ground for zones 1 & 2 20 Zone 6 voltage sensing

14 Zone 2 voltage sensing 21 Zone 7 voltage sensing

15 Zone 3 voltage sensing 22 Ground for zones 7, 8, & 9

16 Ground for zones 3 & 4 (& 5 on XRSuper6) 23 Zone 8 voltage sensing

17 Zone 4 voltage sensing 24 Zone 9 voltage sensing

18 Zone 5 voltage sensing

The voltage sensing terminal measures the voltage flowing through the 1k Ohm End-of-Line resistor to the

zone's ground terminal. Dry contact sensing devices can be used in series (normally-closed) or in parallel

(normally-open) with any of the burglary protection zones.

10.2 Operational parameters

Each burglary protection zone detects three conditions: open, normal, and short.

The parameters for each are listed below:

Condition Resistance on zone Voltage on right terminal

Open over 1300 ohms over 2.0 VDC

Normal 600 to 1300 ohms 1.2 to 2.0 VDC

Short under 600 ohms under 1.2 VDC

10.3 Zone response time

A condition must be present on a zone for 500 milliseconds before it is detected by the panel. Ensure detection

devices used on the protection zones are rated for use with this delay.

10.4 Keyswitch arming zone

Momentary keyswitches

You can use a momentary keyswitch on a zone programmed as an Arming type for use in arming and disarming

the system without a code.
