Input Circuits

2.3 Input Circuits
The Flex 402 has two IDCs (Initiating Device Circuits) and the Flex 404 has four IDCs. Each
circuit is compatible with System Sensor's i
when the detector becomes dirty and a separate supervisory 'freeze' signal when ambient
temperature falls below the detector rating. The maximum loop resistance limit for each IDC is
100 ohms. The field wiring for each zone is supervised for opens, shorts and ground faults (zero
impedance to ground). All conditions are visually and audibly annunciated.
Each circuit is configured for Style B (Class B) operation and will accept I
normally-open contact devices as well as conventional 2-wire or 4-wire, 24 VDC smoke detectors.
In addition, Zone 1 (IDC 1) on the Flex 402 and Zone 2 (IDC2) on the Flex 404 can be
programmed as combination supervisory and waterflow zones. Refer to the Gamewell-FCI Device
Compatibility Document for a list of compatible devices.
Flex 404 Initiating Device Circuits can be converted to Style D (Class A) by installing the optional
Class A Converter module. Refer to "CAC-4 Class A Converter Module (Flex 404 only)" on
page 24.
