• The Notifier SFP-2402 and SFP-2402E Fire Alarm Control Panels (FACPs) bring the latest in microprocessor technology to conventional fire controls. The SFP-2402 is compatible with the i³™ smoke detectors from System Sensor with drift compensation, maintenance alert, and freeze warning. Automatic synchronization 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.

• Two Style B (Class B) Initiating Device Circuits (IDCs).
• One Style Y (Class B) NAC.
• 24 VDC.
i³™ Technology features:
– Drift compensation automatically adjusts detector sensitivity 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
