Appendix A: Wire Requirements - Honeywell Fire-Lite FL-PS6 Instruction Manual

Table of Contents

Connecting external system accessories to the main circuits must be carefully considered to ensure proper operation. It is important to

use the correct type of wire, gauge and run length for each circuit. The following table lists NAC wiring requirements for the FL-PS6 and

FL-PS10 Power Supply.

The numbers documented in this chart are worst case numbers, based on the conditions listed below. The maximum voltage drop, maxi-

mum loop resistance, and wire length ratings can be increased with lower system current loading.

The FL-PS6/10 is full capacity loaded at 6A/10A.

The FL-PS6/10 is running at the Low Battery voltage of 20.4VDC (at Battery Connector TB15).

Wire lengths apply to Class B wiring, and to Class A wiring returned to the ZNAC-PS card.

NOTE: Calculations are based on Direct-Current Resistance data for uncoated copper wire, per National Electrical Code (2005 Edition)

Table 8, Conductor Properties.

NOTE: These distances reflect the worst case scenario and are based on the correct draw of the highest candela strobes at the low end

of the supported NAC voltage with the entire load at the end of the circuit. Further distances can be achieved by performing a point to point

voltage calculation that more accurately reflects the specific devices used and how they are dispersed on the circuit.
