The specialty relay assembly shall be Alpha Communications® PK407A or equivalent. Relay shall operate from a 12VAC to 16VAC primary voltage source, and shall provide a 'Form C' dry contact relay output, as long as the 12VAC to 16VAC source is present. All wiring to relay shall be low-voltage Class II wiring, installed as per all federal, state, and local electrical codes. Relay shall surface mount right to the finished wall and shall be installed in a suitable environment that is free from excessive dirt, dust, temperature, humidity, grease and water.
Contractor shall observe all local and national electrical and building codes.
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.
The PK407A relays are designed to easily surface mount right onto the finished wall by means of self-stick mounting tabs or by using the mounting holes provided for screw mounting.
Connections are positive screw terminal type, using a barrier type terminal connector strip.
