D9412GV2/D7412GV2 Operation and Installation Guide 8.0 On-Board Points

8.4Point 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.
