Capable of detecting CO, NO2, O2, H2, H2S, CH4, and C3H8 gases (sensors sold separately), this gas monitor that features an intelligent design to reduce the cost of ownership while increasing the flexibility of the application. In addition, this monitor can also operate with existing controller-based gas monitoring systems and wired-wireless gas monitoring system components.
Features
Modbus configuration
Supports Modbus protocol to daisy-chain E3 Point detectors, providing up to 96 points of monitoring on a serial bus. Excellent option for controller based (VA301C) installations common in larger applications. A relay output is provided as an option for activating ventilation directly (e.g. when fan is located in close proximity to detectors).
BACnet IP configuration
This monitors outputs directly to BACnet or other BAS. Alarms, strobes and horns are activated through BAS with link to DCV/HVAC controls. This system design supports new and retrofit installations for large buildings, and can couple with a controller to effectively integrate wired system components. A relay output is provided as an option for activating ventilation directly (e.g. when fan is located in close proximity to detector).
Reflex® keeps you safer
This patented Reflex® technology adds this extra degree of precision and diligence to sensor monitoring to make doubly sure you're safe. Reflex bounces electrical signals into this monitor's electrochemical sensor cell at regular intervals, a form of electronic bump testing and continuous monitoring of cell response.
Plug-n-play ease
This monitors plug-n-play sensor (sold separately) is factory calibrated and works out of the box. Upon installation, this monitor automatically configures for quick operation. You benefit from easier installation and maintenance, and greater adaptability to changing building and safety requirements.
