Fire Detection and Fire Alarm Systems
�@The system consists of sensors (heat detector, smoke detector, etc.), manually operated call points and fire signal distinction/alarm unit. We deal with the system of CONSILIUM, Sweden and other brands.

Portable Gas Detectors
�@Various types of portable equipments are available to detect and/or measure density of flammable/toxic gases and/or oxygen depends on purposes and statutory/optional requirements.
GX-8000(LEL)(Flammable Gas Detector with measurement in %LEL)
GX-8000(Type A) (Multiple Gas Detector for HC or CH4, O2, H2S, CO)
- Suction by built-in pump. Compact and light weight with simple configuration.
- Large display (LCD) with auto back-lighting.
- Intrinsically Safe ATEX Exia II CT4, IECEx and MED approved.
- Optional extension hose available for detecting gases in tanks.
- Detection from high density (Vol.%) to low density (%LEL) (Type A).
- Sensing with thermal-conduct method enables precise detection of HC or CH4 in inerted atmosphere (Type A).

OX-07 (for detection of O2)
- Monitoring O2 Density from a distant place with a remote cable. (Max.30m)
- Intrinsically Safe Construction.
- Large Digital Screen for easy reading.
- Shockproof Rubber Protector as a standard accessory.

GX-2009 Personal Gas Monitor (for detection of HC, O2, CO and H2S)
- Very compact and light weight
- Responding to all range of the applicable gases
- Suction-pump unit is available as an option
