Point Response Time

The control panel scans on-board and off-board point
sensor loops every 300 ms. The Debounce program
item in the Point Assignment section of the software
determines point response time by setting the number
of times the control panel scans a point before
generating an alarm.
The debounce count can range from 2 to 15; therefore,
point response time ranges from 600 ms to 4.5 sec. The
Bosch Security Systems default for debounce count is 2.
Increasing debounce might cause missed
alarms. If you increase the debounce count,
detection devices can enter alarm and reset
without exceeding the point response time.
Use a debounce count of 2 for all points except for
Interior Follower points. Program Interior Follower
points as 3.
