3.6 Board Assembly Diagram
Figure 3.2 Model FCP-75 Assembly
Figure 3.2 shows the circuit boards, and annunciator. If you should need to remove the control board for repair, remove the three mounting
screws which hold the control board in 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 IDP addressable devices (Table 3.3).
3.7.1 Current Draw Worksheet Requirements
The following steps must be taken when determining FCP-75 current draw and standby battery requirements.
1.
For the FCP-75, 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 Calculation Worksheet at 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 2.5A. This is the maximum
alarm current for the FCP-75 control panel.
If the current is above 2.5A you will need to use a notification power expander(s) such as the FIK-5496 NAC Expander, to distribute the
power loads so that the FCP-75 or the power expanders do not exceed their power rating. Refer to the current draw worksheets provided
with the FIK-5496 manual so you do not exceed their power requirements.
6.
Complete the remaining instructions in the Current Calculation Worksheet for determining battery size requirements.
