13 2-Way Audio Attribute
–
ON: Panel is able to initiate a 2 way audio session.
OFF: Only the microphone turns on, initiating a a Listen-in only session. The speaker remains off.
14 Hold Up Verification
–
ON: An alarm from zones of this type can contribute to a verified hold up alarm. Use this attribute with Panic and Hold Up zones.
OFF: An alarm from zones of this type does not contribute to a verified hold up alarm. The zone does not cause the hold up verification timer to start
counting down, or generate a verified hold up if the alarm is detected while the timer is running.
6.3.3 System Times
This section describes how to program various timers applicable to the entire alarm system.
[005] System Times
This is the base menu used by installers to program timers, including system area [000], partition timers [001]-[008], and day-
light saving time [901]/[902].
[000] – System Area
Bell Cutoff Time
System sirens follow this timer. Fire alarms follow this timer if section [014] option 8 (Fire Bell Continues Option) is off. System tampers follow this
timer. The bell cutoff time is programmed in minutes. Valid entries are 001 to 255 minutes.
Keypad buzzer alarms do not follow this timer.
Bell Delay Time
The Bell Delay Timer determines how long the bell will be delayed after a zone alarm event. Valid entries are 000-255 where 000 disables this
feature.
Burglary Verification Timer
If another zone with the Burglary Verification attribute enabled is violated within the duration of this timer, a burglary verified event is communicated
and logged. "Burglary Verified" is displayed on the keypad when the system is disarmed.
The burglary verification timer is programmed in minutes. Valid entries are 000 to 255 minutes.
Holdup Verification Timer
A holdup alarm is immediately communicated to the monitoring station and the holdup verification timer starts. A programmable counter
determines the number of additional holdup events that must occur before the timer expires to create a verified holdup event. Once this happens,
the holdup event is logged and communicated.
Note: Not for use with UL/ULC listed installations. 000 disables this feature.
Zone Loop Response Time
Loop response time is a 3-digit entry from 005 to 255 programmed in 10ms increments. The minimum available loop response time is 50ms (e.g.,
program 005 for 50ms).
Automatic Clock Adjust
This value adds or subtracts seconds from the system clock at the end of each day to compensate for inaccuracies. To determine the adjustment
value, monitor the time lost or gained by the alarm system over a period of time and calculate the average gains or loses.
Example #1: The clock loses an average of 9 seconds per day. Program the alarm controller to adjust the clock by 51 seconds for the last minute of
each day. This speeds up the alarm controller's clock by 9 seconds, correcting the problem.
Example #2: The clock gains an average of 11 seconds per day. Program the alarm controller to adjust the clock by 71 seconds for the last minute
of each day. This slows down the alarm controller's clock by 11 seconds, correcting the problem.
If the Auto-arm time is set for 23:59, any change to the Clock Adjust option will directly affect the Auto-arm pre-alert time.
[001]-[008] Partition 1-8 Timers
The following timers can be applied to each partition.
