Point Response Time 
The control panel scans both 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. Program door points connected to a 
D9210B Access Control Interface Module with a 
debounce of 4.
