A-3 STANDBY AND ALARM POWER REQUIREMENTS
Use Table A-3 to calculate the Standby and Alarm Power requirement of the Kidde AEGIS.
A-3.1 Procedure
1. Insert the actual count of components and devices into the Standby Quantity column.
2. Insert the quantity of these components devices which can be in alarm into the Alarm
Quantity column.
3. Multiply the quantity count by the Each — Standby and Alarm Power and insert these
values into the Total column.
4. Calculate the sum of the values in the Total Standby and Total Alarm columns to arrive
at the Total Standby Power and Total Alarm Power in milliamperes.
5. Divide the mA values for Total Power in Amperes.
1
The Auxiliary Power Output current value stated is the maximum allowed. See Note 6 below.
2
The value stated for the Programmable Relays is for each individual relay when energized.
3
Standby currents should be considered for all Ionization, Photoelectric, Duct and Heat Detectors in the three
Detection Circuits. However, since only one detector can be in Alarm, the Alarm current should only be con-
sidered for the entire Detection Circuit.
4
The value stated for the NACs is the maximum for each. See Note 6 below.
5
For the Alarm current values of Steady Release Solenoids, refer to Appendix B.
6
Since the Power Supply of the Kidde AEGIS unit is rated at 5.4 Amps, the system designer should ensure
that the system circuits are loaded so as to keep the calculated alarm current equal to or less than 5.4
Amps.
