SEM
Introduction
The Simplekey Event Manager (SEM) has eight outputs in the form of double-pole volt
free relays, and eight local inputs. A local input may be a switch or trigger from 3
rd
party equipment. In addition to local inputs, an external reader can be used as a form
of input. Typical uses for the SEM would be lift control where a single reader is used,
and various lift buttons are activated depending on the token holder’s access profile.
The example below shows lift control but also the SEM being used to switch on
lighting at the same time.
