SPS Current Consumption

+24V Sig is used to supply the NACs. It can be made accessible by configuring a NAC as an aux power output (normally energized). The PDI has a 24V Sig bus that is only powered when an SPS is plugged directly on to it. (Not in standard configuration). The 4100 MXP is the only Australian approved card that takes power from this bus. All other cards draw power from +24V Card.

The battery circuit is supervised every 29 seconds. The battery test (custom control) is for 1 hour once per week.

The battery is connected to the charger but is normally disconnected from the bulk supply. During mains fail, and the 1 hour battery test, the battery gets connected to the bulk supply.

The IDNet output is 30V in the normal condition as is used to prolong battery standby. When it is necessary to activate large numbers of output devices on IDNet peripherals (such as piezo sounders), the output voltage is increased to 35V to provide sufficient voltage at the end of line to activate the piezo. The higher voltage state is an alarm condition for the purpose of standby battery calculation.

The following table summarizes battery standby capabilities for the SPS. Voltage assumed is 24 V, which is the rated battery voltage for lead-acid type batteries.
