Honeywell SFP-2404-E Fire Alarm Control Panel Instruction Manual

General

The Notifier SFP-2404 and SFP-2404E Fire Alarm Control Panels (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 compensation, maintenance alert, and freeze warning. Automatic synchronization of audio/visual devices with three selections formanufacturer 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, waterflow 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 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 equirements).
- Detector sensitivity is automatically measured by thedetector, 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 fromthe 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.
Zone 4 is programmable for combination of tamper supervisory monitoring and waterflow alarm.
Form-C Alarm, Trouble, and Supervisory relays.
3.0 A total usable current.
6.0 A total usable current available with optional second transformer.
Control buttons:
- ACK (Acknowledge)
- Alarm Silence
- Reset
- Walk Test
- Zone Enable/Disable (one per zone)
LED indicators:
- Fire Alarm (one per zone)
- Supervisory (one per zone)
- Trouble (one per zone)
- Maintenance (one per zone)
- AC Power
- NAC Disable
- Zone Disable
- NAC Fault
- System Trouble
- Power Trouble
- Walk Test
- Alarm Silence
- Earth Fault (on circuit board)
- Battery Fault (on circuit board)
- Charger Fault (on circuit board)
Piezo sounder for alarm, trouble, supervisory and maintenance.
Optional plug-in 4XTM transmitter module.
Optional plug-in 4XZM zone relay module.
Optional 4XLM transmitter module for RZA-4X remote LED annunciator.
Optional dress panel.

Operation

Activation of a compatible smoke detector or any normally-open fire alarm initiating device activates audible and visual signaling devices, illuminates an indicating LED, sounds the piezo sounder at the FACP, activates the FACP alarm relay and operates an optional moduleused to notify a remote station or initiate an auxiliary control function.
