The Informa may be used as a standalone unit, i.e.
NOT connected to an Intruder Alarm Panel. In this
case, an external supply and switches can be used to
operate the Inputs IP1, IP2 and IP3 to trigger the
Informa. The Inputs can be configured for Active
Low or Active High operation.
a) The diagram below is for an Active Low input
configured using a relay to trigger IP1.
b) The diagram that follows is for an Active High
input configured using a relay to trigger IP1. In this
case the wiring is reversed, and the inputs are
connected to -ve.
