The E-30 handsfree door entry speaker phone is designed to provide quick and reliable handsfree communication and can be connected directly to a CO line or analog PABX / KSU station.
The E-30 features non-volatile memory, a built in dialer, and intelligent call progress detection for automatic hang-up when a call is completed. It can be programmed to dial up to 5 different numbers on ring-no-answer or busy, and can be configured to cycle through these numbers until answered.
For outdoor installations where the unit is exposed to precipitation or condensation, use model E-30-EWP. For more information on Enhanced Weather Protection (EWP), see DOD 859.
