COMSRG - Comm. Surge Protector
Electronic Technician Assistant (ETA)

In some applications, the transient protection on the communications terminals of DDC controllers is inadequate. Examples are roof mounted air handlers, pad mounted air conditioners or chillers – or anything attached to the building’s HVAC system but outside the building envelope.
BAPI’s COMSRG provides the extra muscle necessary to prevent damage. The COMSRG plugs between the communications network and any of the COMBLK, RPTR or TUCOM.

ASSOCIATED ETA PRODUCTS

RPTR - RS-485 Repeater
Standard RS-485 communications are limited to 32 unit loads and 4,000 feet. Extending the network beyond 32 unit loads or 4,000 feet requires repeaters. Each RPTR module allows an additional 32 unit loads or 4,000 feet. The RPTR functions not only as a bus extender, but also as a segment isolator, allowing multiple segments to be connected in a star topology.

TUCOM - Terminal Unit Comm. Block
The TUCOM adds three pluggable screw terminals to the communications port of the Carrier® Comfort System zone controller to simplify wiring.

COMBLK - Comm. Cable Terminal Block
The COMBLK - Communication Cable Terminal Block is a small circuit board designed to simplify the task of terminating communications wiring. The COMBLK fits into the TRK18 snaptrack or any other industry standard 2-3/4 inch snaptrack. Each COMBLK contains four independent circuits with three connectors - one for bus in, one for bus out and a third for wiring to the controller..
