INSTALLATION
Burglary Zones
10.1 Description
On XR20/XR40 panels, terminals 12 to 24 are the nine burglary zones. For programming purposes, the zone
numbers are 1 to 9. The zone conÞ gurations on terminals 12 to 24 are described below. The XRSuper6
terminals 12 to 18 are the Þ ve burglary zones with terminal 16 providing the ground for zone 5 (terminal 18).
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 ß owing 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 protec tion zones are rated for use with this delay.
10.4 Keyswitch Arming Zone
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.
