3 Installation and Wiring
Installation of the panel and system accessories requires qualified, trained, and equipped personnel who
are familiar with both the fire alarm codes and installation methods for this specific equipment. Final
programming requires special familiarity with the applicable local codes. The versatility of this system
implies sensitivity to mishandling and misprogramming beyond that of less capable equipment.
3.1 System planning
3.1.1 Battery calculation
The battery provides a secondary source of power if loss of primary power occurs. The batteries need to
have enough capacity to provide power for the control panel and attached devices for a minimum standby
period followed by an alarm period. Follow the directions below to fill in the calculation template in the
appendix.
The first section calculates the current draw loads for standby and alarm conditions.
1. Fill in the quantity and calculate standby and alarm current draw totals for each system
component.
2. Fill in the quantity and calculate standby current draw totals for each detector, base, and module.
3. Use rows A, B, C and D to estimate the total alarm current for detector and module LEDs. Row B
assumes that 5% of the LEDs of these devices will be turned on.
4. Fill in the quantity and calculate total alarm current for each NAC circuit.
5. Calculate the sum columns E and F. Verify that these values are within the limits of the power
supply (see table at the bottom).
6. Verify that the current draw on each circuit is within the current limit of the circuit.
The second section calculates the battery size needed to sustain the loads for the minimum time
durations.
1. Enter the standby and alarm time according to the type of system (see table at the bottom).
2. Fill in and calculate the remaining rows above row h and calculate row i.
3. Row i shows the battery size that is needed. Select a battery that is the next available size bigger
than this value.
3.2 Control panel installation
3.2.1 Preparation
Verify that all installation materials are on-hand. Read all instructions before beginning installation.
To avoid degradation of the operating circuitry, it is recommended that the printed circuit boards be
removed during cabinet mounting, wire installation, and any other procedures that may introduce dust,
metal shavings, grease or any other foreign matter into the area of the electronic circuitry.
WARNING: In an extended system, there may be several sources of power on devices
connected into the control unit. All power must be disconnected during
installation or wiring of system components and not introduced until
installation is complete and checked out.
3.2.2 Panel location
The control unit should be located on the ground floor and easily accessible to authorized personnel. The
area should be reasonably free of dust, vibration, and moisture and a dedicated source of power must be
available. The mounted enclosure should be at a convenient height to facilitate servicing.
