Bieler+Lang GmbH Gas Detection System type : GMC Ecoline 8304 12.600742.2 气体检测系统
Approved to EN 50194
The system is designed to reliably detect natural gas an LPG. Up to four hazard zones can
be monitored. When an alarm situation arises, the controller switches the technical safety
measures at relay contacts and closes a connected solenoid valve in the gas supply line.
A buzzer in the controller gives an acoustic alarm.
Four DC switches (nominal voltage 32VDC/200mA) are incorporated which can be used for
further switching tasks. There are four output relays (230VAC/4A) for connecting further
technical equipment and signalling devices:
- Relay for pre-alarm
- Relay for main alarm
- Relay for acoustic warning devices
- Relay for fault messages
