SPS Auxiliary Power Wiring

Overview

Guidelines

The panel, battery-backed, unregulated dc bulk power is available from the SPS via the NAC and the 24V Aux power terminals (1 pair only, ref fig 7-4). NACs not configured as switched outputs may be configured as auxiliary power point type in the 4100 Programmer. All of these are power-limited.

Review the following guidelines before using the SPS for auxiliary power.

Voltage rating: 24 VDC (nominal), 2 V P-P ripple (maximum).

The total auxiliary current available for non-alarm is 5 A. The total current available for the entire SPS is 9 A, including NAC, auxiliary, and card power.

All wiring is 0.75 mm2 to 4 mm2.

All SPS powered field wiring requires a ferrite bead (ref fig 7.1).

All wiring that leaves the building requires overvoltage protection. Install module

2081-9044 wherever wire enters or exits the building. A maximum of four 2081- 9044 Modules may be connected to one channel.

When a NAC is configured as an auxiliary power circuit, no end-of-line resistor is used.

External wiring is not supervised unless an end-of-line relay is wired, coil to auxiliary power, and Normally Open contacts are monitored by a system power point. Relay current must be considered as part of the load.

Programming is required for the dedicated Auxiliary Power output (TB3).

The following devices may be connected to the 2 A Auxiliary Power:

-2088-series relays and door holders

-2098-series four-wire smoke detectors

-2190-series monitor and signal ZAMs

-4090-series IDNet ZAMs

-4098-series four-wire smoke detectors and duct detectors

-2190-9039 Printer

-4190-9050/9051 4-20 mA ZAMs

-4603-9101 LCD Annunciator

The Auxiliary Power output is rated at 2 A dc.

Where multiple loads are to be connected with individual protection, a Fused DC Distribution board may be fitted directly to the SPS bracket adjacent to TB3.
