Ellis is a versatile, long-range radio trigger that is compatible with all Careium social alarms. It is attractively designed to look less like a traditional radio trigger and destigmatize associations with pendant alarms. Worn around the neck on a stainless-steel chain, Ellis looks more like jewellery. In some cases, the end user is therefore more encouraged to wear their radio trigger, even proudly telling their friends that they are using a social alarm. Ellis is built on the same proven technology as Enzo and is a great alternative for those who want a radio trigger that does not look like an alarm. It is waterproof (IP67) and uses a two-way transceiver that uniquely monitors the connection with the social alarm and provides reassuring confirmation that the alarm has been acknowledged.
