APPLICATION

Rack-based modular system which permits centralising the controls and detectors for the safety monitoring of large industrial or non-industrial premises where a large number of monitoring points are required: eg laboratories, workshops, canteens, garages.

By means of remote sensors the concentration of inflammable gas and carbon monoxide present in the air is monitored, and when the concentration exceeds the threshold value, alarm and security devices are activated.

MUST NOT BE USED FOR FIRE PROTECTION.

Comprises:

  • 1 or more Mounting racks CRM 284 to house all the electronic units..

  • 1 Control unit AGS 013 for each mounting rack: this receives the alarm signals from the detector units, switches on the external alarms and activates a gas safety shut-off valve or an aeration fan.

  • 1 Detector unit AGS 012 for each zone: for monitoring gas leaks (methane or LPG) or the concentration of carbon monoxide, according to the sensor used.

  • 1 Monitoring sensor for each zone: according to type used monitors the concentration of inflammable gases (methane or LPG), or carbon monoxide.

FEATURES

  • Power supply: 230 V ~ o 12 V–.

  • Consumption: 24 VA (Complete rack ).

  • Mounting rack 19".

  • Protection IP 20.

  • Two voltage-free SPDT output contacts: rating 250 V, 10 (2.5) A.

  • Control valves N.O. or N.C.
