✔️ EXTRA LOUD RINGER - The Amplicall 110 is the wireless ringer amplifier of a home alert system designed by Geemarc for the hearing and visually impaired. Provided that you have connected it to your landline telephone using the supplied cable, this device will alert you whenever someone is calling with its 90dB loud alarm and bright visual indicator. If you are wondering how loud that really is, think that the sound made by a hairdryer is usually measured at around 90dB as well. ✔️ CAN WORK WITH OTHER PRODUCTS - The Amplicall 110 is part of the Amplicall range which includes other alert devices such as the Amplicall 101, a powerful doorbell that lets you know when you have visitors, or the Amplicall 140, a sound detector that alerts you when your baby starts crying. Those three devices cannot communicate with one another, but they can all be paired with the same two signal receivers, the Amplicall 100 and 150, which will ring, flash and vibrate each time either one of them gets activated. ✔️ EMERGENCY BUTTON - Not only does pairing the Amplicall 110 with the Amplicall 100 and 150 receivers allows you to get two extra devices with powerful ringers and flashing lights to alert you of incoming calls, it also gives you the possibility of using on the emergency button of the Amplicall 110 to activate the receiver(s) it is paired with. We can thus imagine a scenario where a person with reduced mobility uses the Amplicall 110 to activate the portable Amplicall 150 receiver that someone else in the house is carrying, so as to signal that he or she needs assistance. ✔️ WORKS ON BATTERIES - The Amplicall 110 is powered by two AA batteries (included), but can also be plugged directly into the mains (cable not included). ✔️ OTHER TECHNICAL SPECIFICATIONS – Our ringer amplifier is both wall and desk mountable. Indoors, it can’t be more than 35 meters away from the receiver it is paired with to be able to activate it, this distance increases to 200 meters in open field.
