Table 3 Address Requirements
4.1.2 Power Requirement Calculation
Calculate the current consumption of the control panel and attached devices in
quiescence state and during alarm to determine battery capacity and check if any
auxiliary power supplies are required. Please refer to section Error! Reference source
not found., page Error! Bookmark not defined. for additional details.
An external power supply (TPS-74A or TPS-34A) is required if any of the following
conditions are met:
 Quiescence (normal) mode current consumption is more than 0.5A
 Alarm current is more than 4.0A
 Required battery capacity is more than 12AH
Please see section 0 ("When are Auxiliary Power Supplies Needed?") on page 84 for
a detailed explanation about the requirements of auxiliary power supplies.
Please refer to the TPS-34A technical manual for further details.
