Q. Does the Ei100TY have any cable connection and is this the same as the Ei100TYC?

The Ei100TY has now been discontinued and replaced by the Ei100TYC. The units are the same but the Ei100TYC model has an interconnection capability. The detector itself is battery operated; however if you would like the unit to interconnect with other detectors, this can be achieved using bell wire.
