Fire Sprinklers

A fire sprinkler is an automatic suppression head whose glass bulb breaks when the ambient temperature reaches its rating, opening the head and spreading water over the protected area through its deflector. Only the sprinklers at the fire open; the rest stay closed.
Pendent, upright, sidewall and concealed types are offered with 68 °C, 79 °C and 93 °C ratings and 5 mm standard or 3 mm quick response bulbs. ELO and ESFR types for high-rack storage and escutcheons that cover the mounting gap are in the same group.
Main Applications
- Office, hotel and residential ceilings
- Shopping malls and car parks
- Production and workshop areas
- Rack storage (ELO, ESFR)
- Wall mounting in corridors and rooms
- Concealed mounting in decorative ceilings
