The MRP-2001 has six programmable IDCs (Initiating Device Circuits).  Each circuit is compatible 
with System Sensor’s i

 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.  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 i

 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 Document 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.
