COMMUNICATION & SECURITY SOLUTIONS
Allow Employees to Respond to Paging
Messages, Handsfree!
Features
The HF-3W handsfree paging unit allows
employees to respond to a paging message
without reaching for the telephone. It is perfect for
use in city desks, shipping and service applications
where quick answers are needed.
The HF-3W generates its own talk battery and will
interface with unused trunk ports on PABX’s and
key systems, and single line phones, as well as
some telephone systems with a two-way paging
port and a contact closure.
Simply page the intended employee with a
question and they can respond by speaking toward
the paging horn.
Paging and talk-back volume sensitivity controls
are provided.
