Unique manual call point that mimics the feel of breaking glass whilst offering the user the benefits and environmental advantages of a resettable operating element. An indicator drops into view at the top of the window on activation. The unit is then simply reset with a key and is ready for re-use straight away. Extremely attractive, high value look and feel: glass appearance maintains operator deterrence, whilst a visible warning flag confirms activation. Easy installation due to no glass elements that could be broken or incorrectly fitted. Surface mounted, 20mm conduit entry points are provided for ease of installation. Operating temperature -20°C (-4°F) to 65°C (149°F). Fitted with a single pole changeover switch both the normally open and normally closed contacts are easily accessed through the installer terminals Comes with ‘Emergency’ label
