Fire detector ARTON SPD-3.2NO (СПД-3.2НР) smoke optical 4-wire

Fire detector ARTON SPD-3.2NO (СПД-3.2НР) smoke optical point, designed to detect fires in closed rooms of various buildings and structures, accompanied by the appearance of smoke and transmission of the "FIRE ALARM" signal to the control panel. The detector is used in four-wire alarm loops with a nominal supply voltage of 12 V.

If there is no smoke in the sensitive area of the optical system, the detector connected to the control panel will be in standby mode, as evidenced by periodic flashes of the red optical indicator.

The "FIRE ALARM" output signal is generated by closing the relay contacts.

Features:
• Early fire detection
• High resistance to false positives
• 4-wire connection to the control panel
• Indication of standby mode and “FIRE ALARM” mode
• Compatibility with various control panels
• Possibility of installation on both ceiling and wall
• Availability of decorative rings for installation on suspended ceilings
