Description

The SURVEYOR 4B has been designed as a monitoring apparatus for ensuring the safety of boiler plants, battery charging rooms or small units where your operations are at risk due to possible escape of flammable gas leaks.

Developed for the purpose of quick safe detection, the SURVIVOR 4B control module combines highly reliable monitoring, simple implementation and low costs.

The SURVEYOR 4B is designed to allow easy integration simply by clicking it into place on an existing equipment cabinet near your control devices. The SURVEYOR 4B is linked to detectors set up in the area to be monitored

Simple ergonomics, greater safety

• EASY TO INSTALL
• MAXIMUM SAFETY
  • The measuring line and the detector are monitored in continuous mode by a special circuit which gives warning of any failure.
  • The siren, revolving light or modem, etc., are actuated by dry contacts.
  • The relay can only be reset by acknowledgement in manual mode after the gas alarm has been cleared (automatic acknowledgement on option).
• GREATER SAFETY
  • Faliure: yellow
  • Gas: 1st threshold : red
  • Gas: 2nd threshold: red
  • Integrated audio alarm.
• COMPLIANCE WITH STANDARDS
  • CE and Low – Voltage Directive
