Disclosed are an extinguishing capsule and a capsule type fire extinguisher including the same, the capsule type fire extinguisher including at least one extinguishing module including a housing configured to receive an extinguishing capsule therein, the extinguishing capsule including an extinguishing material that expands when heat is applied thereto, the at least one extinguishing module configured to release the extinguishing material from the housing to suppress fire, and a main module configured to control the at least one extinguishing module and bidirectionally communicate a fire situation to a fire station or a user terminal.

There are a large number of different sprinklers which are used in firefighting installations, in particular a water extinguishing installation having a blocking and an enabled state, wherein the extinguishing fluid-conducting element has a fusible link opening element having a predetermined electrical resistance, wherein the fusible link opening element is integrated in an electrical circuit which has a switch (S) and through which when the switch (S) is closed there flows a current by which the fusible link opening element is opened.

Devices, apparatus, systems, and methods for providing and retrofitting sprinkler heads. with a solid one-piece Teflon saddle and a stainless steel washer to replace a Beryllium washer with Teflon tape on both sides in sprinkler heads. The Teflon saddle can be formed from one piece of Teflon having a cylindrical base and an upper cylindrical section having a raised cylindrical rim, the upper cylindrical section having a wider diameter than the cylindrical base, and narrow depth central opening in the upper cylindrical section. The upper cylindrical section can have a bottom edge having an incline between approximately 10 degrees to approximately 20 degrees running from an outer perimeter to an inner end.

A thermal triggering element having a vessel body with an outer wall formed from a rupturing material, and having a cavity enclosed by the outer wall and situated in the interior of the vessel body, and in which a triggering liquid is enclosed. The vessel body is formed so as to extend along an axial direction, with a tubular central section extending in the axial direction, and with two end sections located at the respective axial ends and in which the cavity is closed off in the manner of a cap. In order for the thermal triggering element to be protected against damage by shocks, the triggering element has a permanently acting reinforcement which reinforces the rupturing material with respect to shock loads acting transversely with respect to the longitudinal direction.
