Multi-Point Type Applicable Detector Head Model

Multi-Point Type Indicator Unit/ Alarm Unit Outline An indicator unit supplies power to the gas detector head and processes the signals from the detector. It displays the gas concentration in 3-color LED bar-graph, it will activate the alarm automatically at alarm set value and transmit the signals to the alarm unit and external output devices (contact output, analog output). Part Names The alarm unit receives the signals (non-contact output) from V3 series indicator unit, displays the alarm (buzzer and lamp), and outputs control contacts to external devices. V3 series POWER Lamp TROUBLE...

Terminal arrangements Alarm unit dimensionsPanel cutout dimensions 1 For one-by-one instrumentation For multi-point close instrumentation Indicator unit dimensions Terminal arrangements 1 (Front side of a panel) Floor Type V-830Outline Use example V-830 gas detector is a compact floor type system of which panel is equipped with single cases incorporating indicator units and an alarm unit, and is best suited for multi-point monitoring.

Multi-Point Type Outline ■ V-810 gas detector is a compact system of wall (panel) mount type which combines indicator units, an alarm unit, and various gas detector heads of the V series. ■ Detects combustible gases, toxic/specialty gases, and oxygen (oxygen deficiency) and gives an alarm signal when the gas concentration goes over a set value (or under a set value for oxygen deficiency), so as to prevent gas accidents such as gas explosion, poisoning, and oxygen deficiency. ■ VB-810 incorporates a backup power supply unit. FEATURES I Compact design. ■ Standard cases for 3/6/9/12/15/18/21...

Multi-Point Type Gas Detection & Alarm System NV Series System Configuration FEATURES Monitors gas leakage even during a power failure or other lifeline failures.(on models with a built-in backup power supply) Continuously monitors for 30 minutes after a power failure, then intermittently monitors for 2 days. The interval between observations depends on the number of detection points. (NV500) Continuously monitors for 30 minutes after a power failure. (NV-400/410/600HS) Operated normally in a seismic qualification test equal to intensity of 7 on the Japanese earthquake scale....
