Exhaust gas detectors with relay output
Swedish company produces reliable exhaust gas detector to control ventilation in parking, garages, etc. They can be 2 models:
• Room mounting (IP21 or IP54)
• Duct mounting
The detectors can be used as stand alone, connected to a monitoring unit or other monitoring systems.
Relevant alarm levels depend on application. Detectors supplied as standard for specified gas with preset alarm levels.
KEY FEATURES
• Microprocessor controlled unit with LED status indication
• Three alarm levels
• Easy to change alarm levels (with use of service tool SA200)
• Selectable alarm time delay
• Manual / automatic alarm reset
• Built-in service mode, self-test and ”Fail-safe” function
• Three SPDT relay outputs (230V / 5A)
• Temperature range -40oC - +50oC
• Long time stable and 8-10 years lifetime
• Power supply 230V AC or 12-24V AC/DC

The detectors are designed to control ventilation (fans) in parking areas. The gas sensor is NOT specific to carbon monoxide (CO) and the sensor will also react to other gases and fumes which may be present in parking areas such as fuel vapour, exhaust emissions and hydrocarbons.
