Initiating Devices
A.3 Initiating Devices
Releasing zone initiating devices include the following:
• FST-851 intelligent heat detectors
• FSI-851, FSP-851, FAPT-851, FSL-751 intelligent smoke detectors
• Conventional detection UL-listed devices connected to monitor modules
Refer to the SLC manual for the most up-to-date information about initiating devices.
You can use multiple initiating devices for the same releasing hazard. Do so by mapping initiating
devices to the same Releasing Zone. Factory Mutual and certain Local Authorities Having
Jurisdiction require using redundant wiring (NFPA 72 Style 6 or Style D) for initiating devices in
releasing applications.
A.4 Warning Sounders
Warning sounders connect to any of the four panel NACs, or to control module circuits (refer to the
NF2S-640 Installation Manual). Note the following:
• If selecting Cross Zones, a warning sounder only activates when two zones alarm.
• Warning sounders—unlike release solenoids—do not wait for a Delay Timer.
• If Coding Functions are required for warning sounders, use one of the NACs—not a control
module.
• The same releasing hazard can activate multiple NACs.
Instructions for activating warning sounders:
To activate a sounder
When the Delay Timer starts, when the
releasing device activates, or both
Immediately when one of the initiating
devices activate
A.5 Auxiliary Control Functions

NFS2-640/E Programming Manual — P/N 52742:L2 7/17/14
Do this
Map the control module or NAC to a releasing hazard zone
(R0-R9).
Map the control module or NAC to a separate zone (not R0-R9)
that is also mapped to all initiating devices of the hazard.
Do this
Use control modules set for dry contact operation. Program the
control relays for different functions by following the instructions
in "To activate a sounder" above.
Use an ACM-8R remote relay module mapped to the software
zones of the control panel.
Do this
Select ACS Selection Group B to annunciate any of the software
zones described previously, including zones R0-R9. For
instructions, refer to "Annunciator Options" on page 33.
Select ACS Selection Group H, I, J, K or L. For instructions, refer
to "Annunciator Options" on page 33.
