Sigma XT Main/Reserve Duty Extinguishant Keyswitch Unit

The K13480M10 Main/ Reserve switch provides a convenient and secure means to operate a switch to reserve extinguishing system agent where such provision is made as a back up to the main agent.

The “901” key is common to many fire detection and protection control panels and is removable in either position.

The robust enclosure allows for either surface mounting or mounting to a single gang flush box.
