General
The Notifier SFP-2404 and SFP-2404E Fire Alarm Control Pan-
els (FACPs) bring the latest in microprocessor technology to
conventional fire controls. The SFP-2404 is compatible with the
i³™ smoke detectors from System Sensor, with drift compensa-
tion, maintenance alert, and freeze warning. Automatic synchro-
nization of audio/visual devices with three selections for
manufacturer protocol. The Notification Appliance Circuit (NAC)
protocol can silence audible devices while strobes continue to
flash, using a single pair of wires.
The SFP-2404 is compatible with conventional input devices
such as two- and four-wire smoke detectors, pull stations, water-
flow devices, tamper switches and other
normally-open contact
devices. Refer to the
Notifier Device Compatibility Document
15378 for a complete list of compatible devices.
Note: Unless indicated otherwise, the term “SFP-2404” refers to
both SFP-2404 and SFP-2404E models.
Features
• Four Style B (Class B) Initiating Device Circuits (IDCs).
• Two Style Y (Class B) NACs.
• Optional module that converts all four IDCs and two NACs to
Class A operation.
•24 VDC.

i³™ Technology features:
– Drift compensation automatically adjusts detector sensitiv-
ity and increases resistance to false alarms caused by dust
accumulation.
– Maintenance Alert LEDs (per zone) warn of excessive dirt
accumulation, preventing false alarms (meets NFPA 72
requirements).
– Detector sensitivity is automatically measured by the
detector, which automatically adjusts its sensitivity back to
the factory settings when it becomes more sensitive due to
contaminants settling in the chamber.
– Wireless handheld sensitivity meter eliminates the need for
voltmeters, magnets, and a physical connection to the
detector. The reader displays sensitivity in terms of percent
per foot obscuration and provides text status indication.
– Supervisory LED (per zone) provides warning if a detector
senses temperature approaching freezing.
– Special test protocol and LED indication allows quick test of
all detectors without need for a ladder.
• NAC synchronization features:
– Synchronization of standard ANSI audible signals as
required by NFPA 72.
– Synchronization of ADA compliant strobes per NFPA 72.
– Selectable for System Sensor, Wheelock, and Gentex
protocols.
– Selective Silence feature for manual silence of horns
while strobes continue to flash on the same NAC.
–
Alarm verification selectable for each zone.
– Disable switches provided per zone.
• NACs programmable for:
– Silence Inhibit
– Auto Silence
– Strobe Synchronization
– Selective Silence (horn-strobe mute)
– Temporal or Steady signal
– Silenceable or Nonsilenceable
• Silent or audible Walk Test operation mode commanded from
the front keypad, with automatic return-to-normal after one
hour of inactivity.
• Each zone may be programmed for supervisory or fire; each
zone has separate red and yellow LEDs.

sory monitoring and waterflow alarm.

transformer.
