5.2 Product description
EC II GSM SE is an alarm equipment for the GSM network with built in duplex speech com-
munication designed for installation in lifts. It complies with requirements according to
EN81:1–2 and EN81:28. The product is CE-marked.
The system consists of two separate units, one central unit which is mounted on top of the
roof of the lift and one speech unit that is mounted inside the lift car and the two units are
joined together with a modular cable.
When someone inside the lift pushes the alarm button, the EC II GSM SE automatically calls
an alarm centre or a predefined alarm receiver and indicates where the alarm comes from. At
the same time voice communications is established and the person in distress can speak di-
rectly to staff at the alarm centre from where help will be dispatched.
EC II GSM SE is normally programmed via a keypad on the rear side of the speech unit but
can also be remote programmed via SMS.
