Tủ Trung Tâm Báo Cháy 4 Zone SFP-2404E Notifier

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
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.
