Installation Input Circuits
2.3 Input Circuits
The GF505 has five IDCs (Initiating Device Circuits) and the GF510 has ten IDCs. Each circuit is compatible with System Sensor’s i
3
smoke detectors which generate a maintenance signal when the detector becomes dirty and a separate supervisory ‘freeze’ signal when
ambient temperature falls below the detector rating of approximately 45
o
F. The maximum loop resistance limit for each IDC is 100 ohms
(700 ohms per zone for linear heat detection). Do not use 2-wire smoke detectors on input zones used for linear heat detection. The field
wiring for each zone is supervised for opens, shorts and ground faults. All conditions are visually and audibly annunciated.
Each circuit is configured for Style B (Class B) operation and will accept i
3
smoke detectors, any normally-open contact devices as well
as conventional 2-wire or 4-wire, 24 VDC smoke detectors. Refer to the Gamewell-FCI Device Compatibility Document for a list of
compatible devices.
