STR Audio Handset with Rotation Switch

STR HT40-RS-W Audio Handset with Rotation Switch

A handset that's actually pleasant to use makes all the difference to how residents feel about their entry system. The STR HT40-RS-W is a surface-mounted audio handset for Qwikbus two-wire systems, with calls answered simply by lifting the handset - no fumbling for a button while juggling shopping bags.

A dedicated door release button sits alongside additional function controls, ring volume is continuously adjustable, and a mute function with a visual status indicator lets residents go quiet without missing a call. Eight selectable door call ringtones plus a fixed floor call tone mean occupants can tell a visitor from a neighbour before they even pick up, and the ultra-slim 20mm surface housing keeps the hallway looking tidy.

Whether it's a single-family home, a block of flats, an office, or a school, the HT40-RS-W is part of the STR Qwikbus indoor station range, built for straightforward installation and everyday reliability in new Qwikbus systems or as a replacement for existing handsets.
