AFP-200 Instruction PN 15511:F2 10/11/99 93
Initiating Devices
Initiating devices may be FDX intelligent heat detectors, SDX or CPX intelligent smoke detectors, or may be
conventional detection devices which are UL-listed for the purpose and connected to MMX modules. Several of
these initiating devices may be used for the same releasing hazard by mapping them to the same releasing zone.
Factory Mutual and certain local authorities having jurisdiction (LAHJ) require that redundant wiring (NFPA 72
Style 6 or Style D) be used for the initiating devices in releasing applications.
Warning Sounders
Warning sounders are connected to any of the four Notification Appliance Circuits or to CMX module circuits
as described earlier in this document. Multiple Notification Appliance Circuits may be activated by the same
releasing hazard.
To activate when the delay timer is started, and/or the releasing device is activated, the CMX module should be
mapped to the releasing hazard zone (91, 92, 93 or 94). Note that if cross zoning is selected, this sounder will
only activate when two zones are in alarm. Also note that, unlike the release solenoids, the sounders do not wait
for the delay timer.
To activate immediately when any one of the initiating devices are activated, the CMX should be mapped to a
separate zone (not 91, 92, 93 or 94) that is also mapped to all initiating devices of the hazard.
Note: If coded sounds are required for warning sounders, they must use one of the four panel Notification
Appliance Circuits, not a CMX circuit.
Auxiliary Control Functions
If control relays are required for release application, CMX modules set for dry contact operation may be used.
They may be programmed for different functions the same as warning sounders described above. Control
functions may also be provided by use of the RTM-8 module or the ACM-8R remote relay module mapped to
the software zones of the control panel.
ACS Annunciation
ACS point annunciation of releasing functions can be done by annunciating any of the software zones described
above, including zones 91, 92, 93 and 94. ACS annunciation of individual detectors may be achieved by
assigning each detector to a separate software zone and annunciating the zone.
Deluge/Pre-Action Release
When using this configuration for Deluge and/or Pre-Action Services, wiring must be configured to maintain a
minimum voltage on releasing circuits. Calculation of maximum allowable resistance:
R
MAX
= V
D
I
S
Where R
MAX
= maximum allowable resistance of wiring, I
S
= solenoid current, and V
D
= allowable voltage drop.
Notes:
• Factory Mutual requires 90 hours of standby power, Style D (Class A) wiring on all Initiating Device
Circuits and V
D
= 0.2 volts.
• For NFPA 13 and 15 applications, the soak timer must be disabled.
• For NFPA 16 applications, the soak timer may be set to 10 or 15 minutes.
• For UL-listed and FM approved Solenoid Release Valves, refer to the Device Compatibility Document.
