General Information
GAI-Tronics Corporation offers intrinsically-safe (I.S.) telephones and isolation barrier units (IBU),
which conform to all pertinent requirements in the USA and Canada. For convenience, a telephone and
an IBU can be purchased together under a single model number: Model 261-001 for indoor use, and
Model 271-001 for outdoors.
However, for rack-mount configurations or special applications, the telephones and IBUs can be
purchased separately:
•
Model 262-001 Indoor I.S. Phone
•
Model 272-001 Outdoor I.S. Phone
•
Model 263 Isolation Barrier Unit
The I.S. telephones are designed to be installed in all hazardous areas. The IBU or rack-mount card unit
is placed in a non-hazardous area up to one mile from the phone, limiting the energy levels going to the
hazardous area to conform to intrinsically-safe requirements.
The Model 263 Isolation Barrier Unit is constructed of durable glass-reinforced polyester, which is highly
resistant to chemicals and weather, and is rated Type 3R (rainproof).
