Point Response Time; Wiring Information For Installations Using The Rothenbuhler 5110/4001-42 High Security Bell - Bosch D9412GV4 Installation And System Reference Manual

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
D9210C 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.
The UL Listed Model 5110 Bell and Model 4001-
42 External Line Balancer (both made by
Rothenbuhler) must be used for the bell and
balanced line module in bank safe and vault
applications.
1. Remove all power from the control panel.
2. Use six-conductor 18 AWG (1.2 mm) 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 14 on page 45 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 22 AWG
(0.8 mm) cable.
5. Wire the 4001-42 to the control panel. Refer
to Figure 14 on page 45 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.

requirements, refer 17.3
