Product overview
PSTN and PBX Compatible. Line-Powered. No IP Network Required.
The HWT-1A-LHB is HEPDA's industrial analogue telephone for sites that run on PSTN lines, FXS ports, or traditional analogue PBX infrastructure. It draws power directly from the telephone line — no PoE switch, no external power supply, no additional wiring required. That simplicity matters in locations like highway emergency call points, tunnel emergency phones, and remote industrial sites where power availability is limited and installation needs to be fast and uncomplicated.
The call transmission specification (SLR <12, RLR <-1, STMR >10, 600-ohm output impedance) is rated for transmission runs up to 5km — relevant for long-haul cable runs across highway or rail infrastructure. Housing size and style can be customised to project requirements.
