SFP-2404 4-Zone Control

คุณสมบัติ

The SFP-2404 is UL Edition listed conventional fire alarm control panels with two alarm initiating zones and four initiating zones respectively. The Notification Appliance Circuit (NAC) protocol can silence audible devices while strobes continue to flash, using a single pair of wires.

Features & Benefits:

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
4-zone: 4 Class By/Style B zones (Class A/Style D optional); 2 Class B/Style Z (Class A/Style Z optional)
3 Amps (expandable to 6.0 AMPS on 4-zone) with programmable strobe synchronization
