Current and Validation Example
The example shown below refers to the specifications needed to help ensure the correct installation of a Protege
controller. Specifications should be validated to ensure that individual maximum currents and total combined
current are not exceeded.
Example
External Devices Connected to Panel
4 EDGE PIR Motion Detectors (Inputs 1-4) connected on AUX1 Output
4 EDGE PIR Motion Detectors (Inputs 5-8) connected on AUX2 Output
1 30W Siren (1.1A (1100mA) @ 13.8VDC)
Current Consumption
Total Combined Current before shutdown 3.4A (3400mA)
Operating Current 120mA (Typical)
DC Output (AUX1) 4 EDGE PIR Motion Detectors @ 15mA each (Total 60mA)
DC Output (AUX2) 4 EDGE PIR Motion Detectors @ 15mA each (Total 60mA)
Siren on Bell Output 1.1A (1100mA)
Total Consumption 1.34A (1340mA)
Validation
Is the total DC Output (AUX1) current less or equal to 1.1A (1100mA)? Yes, it is 60mA
Is the total DC Output (AUX2) current less or equal to 1.1A (1100mA)? Yes, it is 60mA
Is the Bell current output less or equal to 1.1A (1100mA)? Yes, it is 1.1A (1100mA)
Is the total combined current less or equal to 3.4A (3400mA)? Yes, it is 1.34A (1340mA)
