CrystalTime Adj

Default:	No
Selection:	Yes or No
Yes	Set the clock time control on the
	control panel to the on-board crystal
	frequency.
No	Do not set the clock time control on
	the control panel to the on-board
	crystal frequency.

When set to Yes, the control panel switches its clock time control from the traditional AC frequency to the on-board crystal frequency. This prompt replaces the alternate function that was enabled by setting the Silent Alarm Relay for Area 4 to a value of 60.

Perimeter Relay

Default:	No
Selection:	Yes or No
Yes	Change the function of the area-wide
	fail-to-close relays to follow the
	perimeter armed states of their
	areas.
No	The area-wide fail-to-close relay
	operates normally.

When set to Yes, the A# Fail to Close relay becomes an area-wide perimeter armed relay. This relay is activated when all areas assigned to the same relay have perimeter points that are armed. This prompt replaces the alternate function that was enabled by setting the Silent Alarm Relay for Area 7 to a value of 63.

Early Armed Relay

Default:	No
Selection:	Yes or No
Yes	Change activation of Area Armed or
	Perimeter Armed Relay to the
	beginning of the exit delay time.
No	Maintain the activation of Area
	Armed or Perimeter Armed Relay at
	the end of the exit delay time.

When this prompt is set to Yes, the Area Armed or Perimeter Armed Relay activates at the beginning of the exit delay time. This prompt replaces the alternate function that was enabled by setting the Silent Alarm Relay for Area 8 to a value of 64.

6.9Cross Point Parameters

This section discusses the requirements necessary to program Cross Point functions.

Use the Cross Point function on non-fire points only.

The Cross Point option reduces false alarms. Points can be programmed so that the control panel needs to see an Alarm condition within a programmed period of time (called Cross Point Time) from at least two points within a Cross Point Group (Table 43) before Cross Point Alarm Events are generated. These points must have P## Cross Point set to Yes to generate this event.

There are 31 Cross Point Groups in the D9412GV2 and ten in the D7412GV2. Each Cross Point Group consists of eight points and is identified by the point numbers in them (for example, Cross Points 1 to 8, Cross Points 9 to 16, and so on). The maximum number of points that can be programmed to meet the Cross Point criteria is two. Point numbers from different Cross Point Groups do not affect each other. Refer to Table 43 for a complete listing of Cross Points comprising each Cross Point Group.

When any point with P## Cross Point set to Yes detects an alarm condition, the control panel starts a timer as programmed in the Cross Point Time prompt.

If a second Cross Point within the same Cross Point Group detects an alarm condition, the control panel creates a Cross Point Alarm Event for both points, provided both points activate inside the Cross Point Window. A Cross Point is considered to be in alarm when it meets the criteria for Instant Alarm response. The Cross Point index must have P## Pt Response set to a value that generates an instant alarm response.

If a single Cross Point detects an alarm and stays faulted throughout the duration of the Cross Point Window, a standard Alarm Report is generated for that point.

Conversely, if a single Cross Point detects an alarm, then restores, and no other conditions occur, an Unverified Event is generated for that point. A second alarm on the first point does not create an Alarm Event but rather an Unverified Event.
