Bosch Appliances D7412GV3, D9412GV3 manual Point Response Time

D9412GV3/D7412GV3 Operation and Installation Guide 8.0 On-Board Points

8.4Point 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

4.5sec. The Bosch Security Systems, Inc. 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:

Use 3 for Interior Follower points.

Use 4 for door points connected to a D9210B Access Control Interface Module.

8.5Wiring Information for Installations Using the Rothenbuhler 5110/4001-42 High Security Bell

Warning: Wear ear protection when installing and testing the Rothenbuhler High Security Bell.

Sound levels greater than 95 dBA at 3 m (10 ft) can occur.

1.Remove all power from the control panel.

2.Use six-conductor 1.2 mm (18 AWG) shielded stranded wire between the control panel and the 5110 Logic Board (located in the bell enclosure).

3.If you do not have a Silence switch, temporarily install a 1  resistor across TB1-1 and TB1-6 on the 5110 Logic Board. The resistor keeps the 5110’s bell silent during the installation and alignment procedures. Also place a temporary wire jumper across the TB1-6 Bell Relay and TB1-7. Refer to Figure 15 on page 35 for wiring a Silence switch.

4.Mount the D8108A’s 4001-42 External Balanced Line Module and wire it to the 5110 Logic Board using two-conductor 0.8 mm (22 AWG) cable.

5.Wire the 4001-42 to the control panel. Refer to Figure 15 on page 35 and the Rothenbuhler installation manual.

6.Before supplying AC and DC power to the control panel and bell, ensure you are wearing ear protection. The bell sounds for 2 sec and then silences during power up.

For additional information about bell requirements, refer to Bank Safe and Vault Applications in the D9412GV3/D7412GV3 Approved Applications and Compliance Guide (P/N: F01U143069).
