The K-1900-7 panel hot-line phone will auto-dial a 1-32 digit programmable phone number each time the handset is lifted. The unit will touch tone or pulse dial and will not auto-dial on incoming calls.
The K-1900-7 hot-line phone housing consists of a heavy gauge stainless steel panel, an armored cable, a heavy duty handset, and an all metal cradle. The K-1900-7 can be easily touch tone programmed at the shop or installation site. All programming is stored in non-volatile memory.
The K-1900-7-EWP shares all of the features of the K-1900-7 in addition to Enhanced Weather Protection (EWP) for outdoor installations where the unit is exposed to precipitation or condensation. EWP products feature foam rubber gaskets and boots, sealed connections, gel-filled butt connectors, as well as urethane or thermal plastic potted circuit boards with internally sealed, field-adjustable trim pots and DIP switches for easy onsite programming.
