Individual Barrier Configuration:
For applications requiring just a few phones, we recommend that the Intrinsically-Safe Telephones be purchased on an “individual” basis. Each phone (Model 262-001 or 272-001) should be ordered with its own wall-mountable Isolation Barrier Unit (Model 263-000). The Isolation Barrier Unit houses both the PCBA and the Power Supply for the telephone. For convenience, a single model number has been established to order an indoor (Model 261-001) or weatherproof (Model 271-001) combination of these units.

Rack Barrier Configuration:
For larger systems, or where limited space makes mounting of Isolation Barrier Units difficult, GAI-Tronics offers a Rack Barrier Configuration. A standard 19” rack, customer-provided and centrally-located, houses the electronics for the Intrinsically-Safe phone system. GAI-Tronics provides a standard 19” Subrack (Model 267-001), which houses the Power Supply (Model 266-001) and the Line Card (Model 265-001) associated with each telephone. The central cabinet will also house a Patch Panel (Model 268-001) to properly wire the system.
