10.3Zone 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.

10.4Keyswitch 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

11.1Terminals 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 Ω 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.
