Description
Four IDCs, each supporting up to 30 Simplex smoke detectors (4098-9601, 4098-9602, 4098-9605) or
heat detectors (4098-9612, 4098-9613, 4098-9614, 4098-9615). IDCs also support up to 30 Thorn model
612P or 612HP Smoke Detectors; OR up to 20 Thorn model 612H, 622H or 632H Heat Detectors. 50Ω
wiring limit. Each IDC is supervised for ground faults and open circuit faults. (Single hazard, agent release
applications use IDCs 3 and 4 for connecting a pressure switch and supervisory device. Combination
Agent Release and Preaction/Deluge applications (10-11) use IDC's 3 and 4 for waterflow and supervisory.)
The panel interprets a current-limited or short circuit (non-Style C) on an initiating device as an alarm.
Alarms latch until cleared and reset.
Agent release systems use the SPM1 and SPM2 circuits to connect manual release switches and abort
switches. Applications 10 and 11 (agent release and preaction/deluge) use SPM1 for Abort/Manual and
SPM2 for a pressure switch. Neither SPM circuit supports the connection of smoke detectors. Switches
must be normally open. An activated release switch overrides the abort switch. The system tracks the
abort switch status to detect the release of the switch.
