The Industrial M51‐691 Series Phon‐Com Zone Command Units can accommodate any combination of master/slave Phon ‐Comm units up to a maximum of 20 units. The slave units can be configured for standard operation, or to comply with current (2014) Canadian elevator codes for elevator communication applications. Any activated station is routed to the appropriate telephone line where a pre‐programmed telephone number will be dialed. When the telephone line initiates ringing, the intercoms audio circuit will be transferred to the external telephone line for hands-free communication between users.

Before leaving the factory all Minelec Industrial Communication Systems undergo a double approvals process. The first step is safety approval on all the equipment contained in the Mincom Communications Cabinet. In addition, the complete cabinet including all wiring is ESA/CSA inspected and certified and is identified by a unique serial number identifier that is riveted to the completed Mincom Communications Cabinet.
