KnowzNet™ is a control panel-based fixed gas monitoring system supporting up to 8 remote sensor heads.

Sensors are available for a number of combustible and toxic gases - as well as for oxygen, helium and refrigerant gases.

Sensor heads can be installed up to 300 feet (100m) away from the panel.

Panels operate at 12VDC or 24VDC with optional battery back-up.

KnowzNet™ Features:

• Wide selection of gas targets
• PPM, % LEL, and % volume monitoring
• 8 bi-color LEDs indicate sensor states
• LCD and 4-button keypad user interface
• Isolated master relay (DPDT)
• Optional dry-contact zone relays (SPST)
• Manual reset or auto-resetting relay operation
• 80dB alarm beeper
• 12VDC operation standard. Powering up to 60VDC optional
• Panel powers remote sensor heads
• Optional 2-, 4- or 8-hour battery back-up
• Sensors connect using 2-pair cable
• Up to 300' (100m) sensor cable length
