Inputs. There are 3 sets of input connections on the Smoke Screen (Alarm Set, Trigger and Hold Off)

circuit’ then the Smoke Screen is prevented from producing smoke. Hence the production of smoke is
controlled using one or a combination of the following:
• Alarm Set–anormallyclosedrelayconnectedacrosstheAlarmPanel‘Set’outputconnections,

• Trigger –anormallyclosedrelayconnectedacrosstheAlarmPanel‘Trigger’or‘Intruder’output

• Hold-off – usually a PIR or movement sensor normally closed output, which opens when the
sensor detects movement, connected to the Smoke Screen “Hold-off” normally closed
connections.
• Additional Hold-off – any form of normally closed relay or micro switch can be connected to
the“Hold-off”connections.WherettedinparallelasanadditiontoaPIRbothdevicesmustbe

Delaying an activation. After the Smoke Screen has received the required 3 inputs to produce smoke,
an activation can be delayed for a period between 0 and 60 seconds (in 1 second intervals). This can be
used to sequence activations in a multi-machine installation. See “Smoke Delay” in the Programming
section.
Stopping an activation.OnceactivatedtheSmokeScreenwillstopproducing‘smoke’beforetheend
of the programmed smoke time only if the Alarm Set is selected to a non-alarm state.
Preventing an activation. To prevent the Smoke Screen from making smoke during a service
inspection under any circumstances select the “Service Mode” dip switch to on (see separate section).
