The SALCO 700 Series  Zone Annunciator and Zone Expander Systems feature an array of components for zone annunciation and remote bypass. Sensors on doors, windows, space detection systems, machines, etc., can be annunciated at remote stations via multi-conductor cable. Systems can be configured in multiples of 8 zones up to 64 zones.

Any zone can be bypassed (taken out of the system temporarily) from a remote station by depressing a non-locking pushbutton.  When a zone is bypassed the LED for that zone flashes to inform the user that a zone is out of the system.  The 701 main processor can be used with almost any control instrument panel including those controls which have multiple zones.  Three standard remote stations can be operated with the system.

The SALCO  700 Series comprises several accessory components which help ensure that most annunciation requirements are met at a very low cost.
