Style C Option
Releasing Application IDC1 IDC2 IDC3 IDC4 SPM1 SPM2 NAC1 NAC2 RAC1 RAC2 Timers Panel AUX Relays
Style C Option Agent Release
Style C Operation: Current limited equals an
alarm; short/open equals a trouble
Same as Agent application above
except all IDCs operate Style C.
Abort
(Style C)
MS
(Style C)
Same as Agent application selected above except SPM1 and SPM2 are associated
with both hazards.
Style C Option Preaction Deluge
Style C Operation: Current limited equals an
alarm; short/open equals a trouble
Same as Preaction/Deluge application selected above
except all IDCs and SPMs operate Style C.
Same as Preaction/Deluge applications selected above except SPM1 and SPM2 are
associated with both hazards.
Notes:
1. SPM1 and SPM2 are combination Manual Release / Abort zones in Agent Release Dual Hazard applications only. A short is a Manual Release and a current limit is an Abort condition.
2. A Manual Release will start the Manual Releasing Timer and operate the NAC cadence pattern associated with the start of the Release Timer in the I/O matrix for the application selected.
3. A Manual Release will override an Abort. In an abort condition the NACs will operate in accordance with the active Stage 1, 2, and 3 operation in the I/O matrix for application selected and the
specific Abort operation selected.
4. Optional operation is selectable for 20bpm or Temporal Code. When Temporal Code is selected for the Alarm NAC operation, the Supervisory NAC signal will be 20BPM. When 20bpm is selected
for the Alarm NAC operation, the Supervisory NAC signal will be temporal.
5. Where Temporal Code pattern is only allowed for evacuation signaling and the Audible NAC operation for 1st Alarm is changed from the default of Temporal Code to 20bpm, NAC 2 should not be
used for Supervisory signaling.
6. In Preaction/Deluge applications 5-8 configured for Class A/B (i.e. non-Style C), a short on any IDC is an immediate manual release.
7. In Preaction/Deluge applications configured for Style C operation, SPM2 activates a manual release of both hazards.
8. For application modes 9, 12, and 13, RAC2 is not used as a releasing circuit; instead it becomes a third NAC.
9. Pre-discharge is any of the following: Cross-Zoned Alarm, Manual Alarm, or Pressure Switch Alarm. Note that this is not 1
st
smoke detector alarm and not waterflow alarm.
10. Discharge tracks the operation of RAC1 and RAC2 and does not engage on waterflow or pressure switch activation.
