2.4 Planning Your Installation
As a minimum, the following points should be considered to ensure that the installation will be successful and
proceed without delay.
•Consult with your local AHJ to ensure that the overall system will meet all requirements. Have your plans
reviewed and approved as required.
•Review the electrical specifications, mounting and wiring instructions in this manual and in the manuals of
all connected modules and devices.
•Using the chart in this manual, calculate the standby battery size that will meet the standby time required.
Include all components that will draw current from the standby battery when the panel is in the ‘standby’
mode.
•Determine the location of the control panel, all initiating and indicating devices and remote modules and
mark them on your system layout plan. An indicating device must be located in close proximity to the control
panel.
•Using the charts in this manual, determine the wire gauge and wire run distances for the connected
components. (initiating devices, indicating devices and ‘secur-bus’ connected components.)
•Review the programming section of this manual and determine the operating characteristics required of the
initiating zones, indicating zones and common panel features.
