Section 2 Hardware Configuration
2.1 System Power
2.1.1 Primary and Secondary Power
The IFI-WS requires connection to a separate dedicated primary AC fire alarm circuit as the primary power
source. The circuit must be labeled "FIRE ALARM" and must connect to the line side of the main power
feed of the protected premises. No other equipment can be powered from the fire alarm circuit. This circuit
must run continuously, without disconnect devices, from the power source to the workstation. Overcurrent
protection for this circuit must comply with Article 760 of the National Electrical Code as well as local
codes.
If available, backup power for the workstation must be supplied by the building emergency power source. A
supervised Uninterruptible Power Supply (UPS) is required to provide power continuity during the
transition period from the primary power source to the emergency power source. The UPS must be UL 1481
listed, regulated, and power limited.
In Canada, backup power for the workstation must be supplied by the building emergency power source. A
supervised UPS is required to provide power continuity during the transition period from the primary power
source to the emergency power source. The UPS must be CSA or ULC listed, regulated, and power limited.
