3.6 Board Assembly Diagram
Figure 3.2 Model 6808 Assembly
Figure 3.2 shows the circuit boards and annunciator. If you should need to remove the control board for repair, do so by removing the nuts
that hold the heat sink bracket to into the cabinet. Then lift the control board out of the cabinet.
3.7 Calculating Current Draw and Standby Battery
This section is for helping you determine the current draw and standby battery needs if you are using SK addressable devices (Table 3.2)
or SD addressable devices (Table 3.3).
3.7.1 Current Draw Worksheet Requirements
The following steps must be taken when determining 6808 current draw and standby battery requirements.
1.
Use the Current Draw Worksheet to determine current draw and standby battery requirements. Use Table 3.2 if installing SK SLC
Devices and Table 3.3 if installing SD SLC Devices to determine current draw. For the 6808, the worst case current draw is listed for
the panel, addressable devices, and all SBUS expanders. Fill in the number of addressable devices that will be used in the system and
compute the current draw requirements for alarm and standby. Record this information in the Current Draw Worksheet on Line A.
2.
Add up the current draw for all auxiliary devices and record in the table at Line B.
3.
Add up all notification appliance loads and record in the table at Line C.
4.
For notification appliance circuits and auxiliary devices not mentioned in the manual, refer to the device manual for the current
ratings.
5.
Make sure that the total alarm current you calculated, including current for the panel itself, does not exceed 6.0 A. This is the
maximum alarm current for the 6808 control panel. If the current is above 6.0 A you will need to use a notification power
expander(s) such as the Silent Knight 5496 NAC Expander, to distribute the power loads so that the 6808 or the power expanders do
not exceed their power rating. Refer to the current draw worksheets provided with the 5496 manual so you do not exceed their power
requirements.
6.
Complete the remaining instructions in the appropriate Current Draw Worksheet for determining battery size requirements.
