Alarm units

Gas alarms for domestic use
Gas alarm for applications in domestic dwellings, with integrated/external  sensor and alarm buzzer.

Highly sensitive reliable alarm units.

Gas alarms systems for industrial and domestic applications GW-S
Compact, freely programmable gas alarm system with wall mounted housing for the connection of 1 or 2 sensors.

The evaluation unit can monitor various types of gases.


Gas alarm system GW-SK in standard DIN-rail housing


Compact, freely programmable gas alarm system with standard DIN-rail housing for the connection of up to 6 sensors with alternating indication of measured values. The evaluation unit can monitor various types of gases.


Gas sensor series 400, 500, 600, 700, 800

Series 400 (semiconductor), 500 (heat tone), 600 (electrochemical), 700 (infrared) and 800 (zirconium dioxide) for connection to gas alarm systems (evaluation units) types GW-S, GW-S4 and GWSK. The gas sensors are connected to the corresponding units.
The sensors are suitable for dusty and dirty environments. Depending on the version (measuring principle), they are used to detect inflammable and explosive or toxic gases.

Electronic gas and smoke detectors

When used with gas and smoke sensors, GRM continuously monitors explosive gases, vapours and/or smoke and generates alarms.

The GRM electronic gas and smoke detector is installed in boiler rooms and basements, storage, office and living rooms as well as public facilities or industrial buildings for increased safety (building technology).

Gas and smoke sensors for GRM:

  • Gas sensor for methane: Part no. 61188A
  • Gas sensor for propane, butane: Part no. 61189A
  • Smoke sensor: Part no. 61151


Test gas unit

For checking gas alarm systems during maintenance and repair work.
