DESCRIPTION 

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. 
All  manufacturing  and  testing  processes  are  performed  strictly  in  compliance  with  our  quality  management  system, 
certified to ISO 9001.The use of precisely CNC-machined hot forged frames eliminates the risk of porosity.  
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. 

 
APPLICATION 

GW-S heat & electrically actuated sprinklers are used in fixed fire protection systems. Care must be exercised that RTI, 
orifice  size,  temperature  rating,  deflector  style  and  sprinkler  type  is  in  accordance  with  the  latest  published  sprinkler 
installation standards i.e. EN12845, CEA4001 or NFPA13. 
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.  
 

OPERATION (Metron Actuator) 

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. 
Its ability to rapidly convert small electric signals into high mechanical work output, its compact size, high reliability and 
good  environmental  resistance  makes  the  Metron  Actuator  ideal  for  automatic  or  remote  controlled  fire  protection 
applications.
