Simplex 4100U Installation & Maintenance

I-1
Part of the system design includes calculating that the quiescent load and the
alarm load are each less than the rating of the power supply.
Note that the quiescent load includes devices such as door holders that are
normally energized, but get switched off during alarm.
The SPS rating is included in the specifications in Chapter 6.
Refer to AS1670.1 Section 8.2.3 for a definition of the loads to be calculated.
Battery capacity requirements are specified in AS1670.1, 2004, Section 3.16.4
with an example shown in Appendix C1.
Calculate the quiescent load (Iq) and alarm load (Ia) from the currents listed in
the specifications (Appendix H of this manual). Follow the example in AS1670.1.
Note that the system current for both the quiescent and the alarm state can be
checked on the panel by use of the System Current status point under Card
Status for the SPS.
