The XR10A/XR20A 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 XR6A terminals 12
to 18 are the five burglary zones with terminal 16 providing the ground for zone 5.

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 XR6A)

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 

W

 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.

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

The parameters for each are listed below:

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

A condition must be present on a zone for 500 milliseconds before it's detected by the XR6A/XR10A/XR20A
panel. Ensure detection devices used on the protection zones are rated for use with this delay.

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.
