2.3 Input Circuits

The MS-5UD has five IDCs (Initiating Device Circuits) and the MS-10UD has ten IDCs. Each circuit is compatible with System Sen-
sor'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
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
as conventional 2-wire or 4-wire, 24 VDC smoke detectors. Refer to the Fire•Lite Device Compatibility Document for a list of compati-
ble devices.
