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. NACs can be configured as auxiliary power point type in the 4100U 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 loads is 5A. The total current available for the entire SPS is 9A, including NAC, auxiliary, and card power.

•The Auxiliary Power output is rated at 2A DC. Programming is required to activate this supply output.

•A Fuse Distribution board is fitted to the SPS bracket and wired to the Auxiliary Power output as standard. Each output from this board is protected by a 1A fuse. Do not fit heavier fuses than 1A since this may defeat the fuse protection. The combined output from the DC Distribution board is limited to 2A.

•All wiring is 0.75 mm2 to 4 mm2.

•All SPS powered field wiring requires a ferrite bead fitted (refer Figure 5.1).

•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 power 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.
