Point Response Time
The panel scans both on-board and off-board point
sensor loops every 300 milliseconds. The Debounce
Count program item in the
Point Assignment
section
determines point response time by setting the number of
scans that a point must be faulted before the panel
initiates an alarm.
The debounce count can range from 2 to 15; therefore,
point response time ranges from 600 milliseconds to 4.5
seconds. The Bosch Security Systems default for
debounce count is 2.
Increasing debounce may cause missed
alarms.
If you increase the debounce count,
detection devices may go into alarm and
reset without exceeding the point response
time.
Bosch Security Systems recommends a debounce count
of 2 for all points except for Interior Follower points,
which should be programmed as a 3. In addition, door
points connected to a D9210B Access Control Interface
Module should be programmed with a debounce of 4.
