This Viking hot-line intercom lets you program a phone number in it so anytime the handset is picked up, it will call that number. It can be programmed to dial up to 5 different numbers on ring no answer or busy and can be configured to dial these numbers until answered.
The intercom consists of a heavy gauge stainless steel panel and a all metal powder-coated housing. The number is programmed into the hot-line intercom using a standard touch tone phone that you provide. Any phone with tone dialing will work. To get into programming mode, you call the phone number of the hot-line phone.
There are two versions of this hot line intercom. The Enhanced Weather Protection (EWP) outdoor version shares all of the features of the non-EWP version 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.
The product mounts on a flat surface or pole.
You will need an analog phone line that this device can connect to and given that analog lines from telephone companies are getting very expensive, we recommend you use a Voice Over IP (VOIP) service which are very cost effective. Below are two that you could use:
