2.3 Input Circuits
The PDRP-2001 has six programmable IDCs (Initiating Device Circuits). Each circuit is
compatible with System Sensor’s i³ 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^oF. The maximum loop resistance limit for each IDC
is 100 ohms. The maximum number of detectors per zone is 25. 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 i³ smoke detectors, any
normally-open contact devices as well as conventional 2-wire or 4-wire, 24 VDC smoke detectors.
Refer to the Device Compatibility Appendix for a list of compatible devices.
Initiating Device Circuits can be converted to Style D (Class A) by installing the optional Class A
Converter module. Refer to "CAC-5X Class A Converter Module" on page 26.
