8.4 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, 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.
8.5 Wiring 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).
