Product Details

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. Simply page the intended employee with a question and they can respond by speaking toward the paging horn.

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. Paging and talk-back volume sensitivity controls are provided.

One Viking model 25AE Paging Horn is included with the HF-3W.
