Alpha PK407A Magnetic Door Opener / MGR Call Relay

The PK407A from Alpha is a magnetic door opener / MGR call relay. The Alpha PK407A specialty relays are used for a variety of reasons. The PK407A can be connected to a standard 12VAC or 16VAC electric door opener output from many intercom amplifiers to allow connection to a magnetic or different type or voltage door opener. It can also be used to provide a 'Form C' relay contact from virtually any 12VAC-16VAC input source. The PK407A can even be powered directly from a 12VAC or 16VAC transformer. As long as a 12VAC to 16VAC source is present, the PK407A will engage, providing a normally-open and a normally closed set of contacts, with a shared 'common' screw terminal.
