3.1 CONTROLLING THE SMOKE
Alarm Panel activation
There are 3 sets of inputs on the Smoke Screen (Set, Alarm and Hold-off) that can be connected to clean contacts.
By default, for the Smoke Screen to produce ‘smoke’ all 3 sets of connections must be ‘open circuit’.
We recommend using the default setting ‘Normally Closed’ to ensure that the Smoke Screen will activate in case the
alarm cables are tampered from the outside. These settings can be reversed – see Section 6.5 Inverting Triggers.
•
Set – a normally closed relay connected across the alarm panel ‘Set’ output connections, which is open
when the alarm panel is ‘Set’ and closed when the panel is ‘Unset’.
•
Alarm – a normally closed relay connected across the alarm panel ‘Intruder’ output connections, which is
open when the alarm panel or controlling device is in ‘Alarm’.
•
Optional - Hold-off – usually a PIR / 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 / micro switch / keyswitch can be connected to the
‘Hold-off’ connections. If fitted in parallel to a PIR both devices must be ‘open’ to produce ‘smoke’.
NB:
If no ‘hold-off’ is fitted the terminals should be left without anything connected and will show ‘HO’ on the display
as in an active condition.
If a ‘Panic’ output from the alarm system is required to trigger the Smoke Screen we recommend using a DPDT relay
connected to break the Set and Alarm Inputs to the SSI – This allows isolation of the Smoke Screen when testing the
alarm system.
Optional Panic input activation
NB:
The Panic trigger mode is delivered set to n/o and the Panic Smoke Time is set to 0 seconds to prevent
inadvertent activation if the facility is not used. ‘Panic Smoke Time’ can be individually set.
The Smoke Screen has a Panic input that can be connected to a clean contact going ‘open circuit’ to activate (this can
be changed to ‘closed = activate’ – see ‘Invert Trigger Mode’ in the Programming section).
It is recommended that the Panic is activated by a momentary, non-latching, button to avoid the situation where a
Panic activation is not reset before a standard activation is required.
WARNINGS:
•
Service Mode should be selected to on if the Panic trigger mode is changed when the Smoke
Screen is at operating temperature.
•
Always restore a Panic input after it has been used. Failure to do so will result in the Smoke
Screen not subsequently activating on an Alarm Panel (Set, Alarm and Hold-off) demand.
