The specialty relay module(s) shall be Alpha Communications® RY012AM or equivalent. Relay shall operate from a 12VDC primary voltage source, and shall provide a 'Form C' dry contact relay output, as long as the 12VDC 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. Relay can also be mounted behind a calling stations, using the provided mounting holes and cable tie or wire wrap.
Contractor shall observe all local and national electrical and building codes.
As long as a 12VDC source is present, the RY012AM will engage, providing a normally-open and a normally closed set of contacts, with a shared 'common' screw terminal.
The RY012AM relays are designed to easily surface mount right onto the finished wall by means of self-stick mounting tabs (provided by others) or by using the mounting holes provided for screw mounting. Convenient mounting holes also allow these relays to be mounted behind calling devices by means of a cable tie or wire wrap.
Connections are positive screw terminal type, using a barrier type terminal connector strip.
