systems.

The unit includes a bypass function for overriding the volume control knob setting when

activated by a contact closure or open collector output. A bypass trim control adjusts the

volume when in bypass mode with a maximum of 2 dB of attenuation.The BUFEX fits into a sin-1

gle gang electrical box.
