Indoor Extinguishant System Ancillaries (Model D-108-POS)


Designed with ease of installation in mind, Demco’s indoor system activation devices D-108-POS series are extremely suitable for open-circuit system.

The shrouded push-button design on Extinguishant Abort Switch D-108-POS-EA and System Abort Switch D-508-EA helps prevent inadvertent operation during the cancelation of extinguishant release sequence. In addition, D-508-EA consists of corrosion-resistance stainless steel faceplate and a modular switch assembly designed to mount on a standard double gang electrical enclosure.

Resettable Extinguishant Release Call Point D-108-POS-ER’s simple ‘RESET’ mechanism consist of ABS plastic operating element that simulates break glass activation which is instantly reusable with no glass elements to break, lose or incorrectly fit when installing.

D-108-POS-EHO Extinguishant Hold Off Switch’s raised push button design is good for quick positive operation or momentary actuation when delaying the immenent suppression agent’s release.
