Metron (Electrically Activated) Products

The GW-S sprinkler series offers high quality, European manufactured, modern compact design, that meet the rigid test requirements set out by the world leading approval authorities. The unique GW PTFE / double groove seal in combination with high end heat responsive frangible glass bulbs guarantee durable operation and reliable performance.

The heat & electrically operated sprinkler is fitted with an electrically operated Metron Actuator that enables instant and remote actuation of the sprinkler – typically in combination with a detection system and/or a manually operated switch box.

The GW-S heat & electrically actuated sprinklers are ideal for applications where instant and fully controllable actuation of single or multiple heads is called for – e.g. applications involving protection of explosive components/environments.

The Metron Actuator is a highly reliable, compact single shot device which can push with a power to weight ratio in excess of 10,000:1. It operates within milliseconds of receiving the appropriate electrical impulse, a rate which is almost impossible to achieve with a mechanical source of energy. The short reaction times and high power to weight ratios are achieved by sophisticated pyrotechnique. Within the metal body of each device, rapid expansion of hot combustion products generates very high pressures which are used to do mechanical work, in this case to drive a piston forward to shatter the sprinkler glass bulb.

Depending on the application GW-S electrically operated sprinklers can be fitted with either the "standard" DR2003/C3 Metron Actuator with red twisted pair cable - or for more demanding applications calling for EMI protection and resistance to challenging environments, the DR2003/C35 Metron Actuator with shielded and white jacketed twisted pair cable.
