Intercom System: Telex

System Designer: Terry Crack

Project Scope:

Pratt & Whitney, Canada’s leading manufacturer of aviation power plants and propulsion engines, utilizes a complex matrix intercom system to maintain communications during the engine testing and R&D phases of their Toronto manufacturing plant. All 12 of the facilities “Test Cells” employ a matrix intercom key panels to maintain constant communication with the “Central Instrument Recording Area” (CRA) during an engine test. The added ability of each system to communicate via a wireless radio link to the technicians in the test cell and throughout the facility is achieved through incorporation of a Telex Radiocom system. Field Service .CA is now under contract to maintain and complete any required repairs to the systems under a Preventative Maintenance Contract.

Notable Features:

Due to the complexity of existing building infrastructure, the installation of the building wide intercom system was designed around a network multiplex system allowing only a single CAT5 Line to be run to each of the test cells. All audio, data and control communication take place over this single twisted pair line. A custom configuration program was written for the venue by Field Service .CA. The system has been running reliably day in and out, providing quality bi-directional communication thought the facility.
