The Model ET-1B Emergency Transmitter is a single-channel transmitter normally used as a "panic button" in security systems. It is also used in many remote switching applications where a portable transmitter is required. Pressing both buttons on the sides of the transmitter at the same time will send a transmission.
The ERU-900 is so easy to use. Residents or family record their own voice message (in any language) then enter the telephone, pager or cell phone numbers that they want it to call in an emergency. When the ERU-900 receives an Emergency Signal, it automatically delivers the pre-recorded message and will even continue call back if the number is busy or there is no answer.
The Good Part Is -- when a called party answers they can "Listen In" and have a 2-Way conversation to determine what the emergency is.
The Best Part Is -- with the ERU-900 technology, I feel safe, secure and confident that the Call For Help message will get through; it's been tested to have an open air range of up to nearly a mile!
There are so many wonderful features with the ERU-900. You will sleep well knowing the ERU-900 is awake 24-hours a day -- 7 days a week. Get the ERU-900 for family, residents, or friends. You will be so happy you did!
