5.0 External Device Power
The FCPS provides filtered 24VDC power that may be used for operating Notification
Appliance Circuits or other external devices. The power for operating external devices
is limited. Use Table 5-1 (standby or nonalarm) and Table 5-2 (alarm) to determine if
external loading is within the capabilities of the power supply.
Refer to the device manufacturer's data sheets packaged with each device to find the
standby and alarm current draws to use in the tables that follow.
5.1 Device Standby Current Draw
The following table should include the total standby current draw of all devices on each
active output, including end of line relays when used for supervision.
