This 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.
The product mounts on a flat surface using a double-gang electrical box.
It connects to a SIP telephone system so you will need your IT/networking people to install this.
