XR10/XR20 Installation Guide
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's detected by the XR10/XR20 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.
How it works
When the Arming zone is placed into a
shorted
codition from a
normal
condition, the panel disarms any areas
that are armed. If all areas are disarmed, the panel arms all areas.
If the Arming zone changes from normal to open while any area is armed, an alarm is indicated. If all areas are
disarmed, only a trouble is indicated.
Powered Zone for 2-Wire Smoke Detectors
11.1 Terminals 25 and 26
A resettable 2-wire Class B powered zone is provided on terminals 25 (positive) and 26 (negative) of the panel.
For programming purposes, the zone number is 10. The zone uses a Model 309, 3.3k EOL resistor (provided
with the panel) and has an operating range of 8.8 to 14.2 VDC.
Power is dropped from zone 10 any
time a Sensor Reset is performed on
the panel. Whenever non-Fire and
non-Supervisory zone types are used
on zone 10, make the appropriate
adjustments to the zone's Armed
Action to prevent false alarms from
occurring.
The UL compatibility identifier is: A.
