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 dependant 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
Quaestor-SZU Releasing Fire Control Panel.
Reference Appendix A, Specifications and Appendix C, Calculations to determine specific operating constraints for
devices and cabling connected to the Quaestor-SZU Releasing Fire Control Panel.
Mounting the Fire Control Panel
This section describes preparing, removing the fascia and mounting the Quaestor-SZU Releasing Fire Control Panel.
Preparing
Complete the following steps to prepare the fire control panel for mounting:
1 Open the cabinet-door of the fire control panel using the door-lock-key.
2 Disconnect the green ground cable from the cabinet-door.
3 Remove the cabinet-door from the cabinet-box of the Quaestor-SZU Releasing Fire Control Panel.
4 Remove the fascia from the cabinet-box.
5 Remove the standby-batteries from the base of the cabinet-box.
6 Mark the location for mounting the cabinet-box to the premises-wall.
