Fusible link (DAS)
Alloy type (bimetallic) fusible link, which acts when the air flow temperature exceeds 72 ºC
(EN 10294) causing the fusible link to smelt. In all the operating mechanism arrangements
it is incorporated as standard in the internal assembly of the trigger mechanism except
where a servomotor with a reset spring is fitted.
Electromagnetic coil (shunt or undervoltage release) (DAS)
There are two types: shunt release or undervoltage release.
Shunt releases are normally de-energised and act via an electric signal (electric
supply)
Undervoltage releases are normally energised and act by removing or breaking the
current supply.
