Determining System Current Draw

Determine the current draw of the fire alarm system for alarm and standby conditions. Use these

maximum current values to obtain the operating constraints of the fire alarm system and the battery
capacity of the fire control panel.

Standby-Battery Capacity

Perform the installation only after calculations have been completed for a suitable battery size. Battery

standby-hours are dependent on battery capacity and load of the fire alarm system.

Reference Appendix C, Calculations to determine the standby-battery capacity of the system.

Operating Constraints

Operating constraints must be included in the planning of the fire control panel to maintain reliable

standby and alarm operation. Operating constraints are based on the current-loading of the fire

control system and the current-driving capability of the fire control panel.

Current-loading in a fire control system can be caused by individual or multiple combinations of zone

circuits, signaling line circuits, notification appliances, initiating devices and cabling. Select circuit

devices and cabling for the fire control system that does not exceed the current driving capability of
the Sigma A-CP Fire Control Panel.

Reference Appendix A, Specifications and Appendix C, Calculations to determine specific operating

constraints for devices and cabling connected to the Sigma A-CP Fire Control Panel.

Mounting the Fire Control Panel

This section describes preparing, removing the fascia and mounting the Sigma A-CP Fire Control Panel.

Preparing

Complete the following steps to prepare the fire control panel for mounting:

Open the cabinet-door of the fire control panel using the door-lock-key.

Remove the cabinet-door from the cabinet-box.

Remove the fascia from the cabinet-box.

Remove standby-batteries from the base of the cabinet-box.

Mark the location for mounting the cabinet-box to the premises-wall.
