Autonomous Gas Detection Devices

Autonomous LPG detector with fire detection zone. It is activated when the gas contents in the monitored
area exceed 5-15% of the L.E.L. (Lower Explosive Level) Conventional fire detection sensors, remote gas sensors and different kinds of electro-valves, can be installed on the special input. It has a built-in sounder, a 5A/230V relay and a good operation test button.

Description

BS-690. Autonomous LPG detector with fire detection zone. It is activated when the gas contents in the monitored
area exceed 5-15% of the L.E.L. (Lower Explosive Level) Conventional fire detection sensors, remote gas sensors and
different kinds of electro-valves, can be installed on the special input. It has a built-in sounder, a 5A/230V relay and a
good operation test button.

> BS-691. Autonomous natural gas detector with fire detection zone. This detector has the same characteristics as the
BS-690 but is suitable for sensing natural gas leaks or alcohol vapors.

> BS-687. Waterproof autonomous LPG detector (IP 42). It is activated when the gas (propane, butane) concentration
level reach 5-15% of the L.E.L. (Lower explosive level. It has a 220V/5A relay and can monitor an area of 25-30 sq.m.
> BS-688. Waterproof autonomous natural gas detector (IP 42). It has the same characteristics as the BS-687 but is
suitable for detecting natural gas and alcohol vapors.

> BS-673. Autonomous natural gas detector with battery back-up. This detector has a suitable output capable of
driving an electro-valve. The built-in battery enables the electro-valve activation even when the mains power supply
fails. It can monitor an area of 25-30 sq.m.

> BS-674. Autonomous LPG detector with battery back-up. It has the same characteristics as the BS-673 but is suitable
for detecting propane-butane gases.

> BS-685. Waterproof (IP 65) LPG detector with relay. It is activated when the gas content (propane or butane) in the
monitored area exceeds 5-15% of the lower explosive level (L.E.L). The incorporated LED lights when the detector is
activated. The command towards that panel is given with a voltage free relay contact.

> BS-686. Waterproof (IP 65) natural gas detector with relay. It is activated when the methane or alcohol content in
the monitored area exceeds 5-15% of the lower explosive level (L.E.L) The incorporated LED lights when the
detector is activated. The command towards that panel is given with a voltage free relay contact.

> BS-658. With a high-quality electrochemical gas sensor and excellent craft work, it has the advantages of good
repeatability, Resistant against temperature and humidity, long life-span and easy operation. It can convert the gas
concentration in the air to a digital signal output with a range of 4-20mA. It is suitable for gas detection in car
parkings or industrial environment where toxic gas leaks.
