SmokeCloak is connected permanently to the mains supply and is triggered into operation by the alarm system. A SmokeCloak react mainly on two inputs, “set” and “trigger”:

Set, terminal 9 & 10
Set signal should come from the alarm panel when the user sets the alarm – e.g when leaving the premises after work.

Unset is the opposite of the set, and therefore the alarm panel should remove the set signal when the alarm is turned off.

It is only possible to trigger the VALI once after the alarm is set, which means that if the VALI shall be triggered more than once, from the Alarm panel, the VALI shall have a UNSET signal in-between.
Unset signal is also used to release lached relayes (only possible with the VALI range).
The system is set by applying 12 V (default) across terminal 9 and 10.
It is via the PC-TOOL possible to invert the means of 12 V, to UNSET, instead of set (only possible with the VALI range).

Trigger, terminal 11 & 12
Trigger signal should come from the alarm panel when the alarm is triggered.
Due to that the VALI will fire if:

• There is a “SET” signal present.
• It has not been triggered before with the current “SET” signal.
• The verification sensor is “activated” or NO verification sensor connected.

N.B. At the VALI range the trigger signal must be set continuously from the initial alarm, until the backstop timer is timed out.

This function is triggered by applying 12 V (default) across terminal 11 and 12.
It is via the PC-TOOL possible to invert the means of 12 V, to untrigger, instead of trigger (only possible with the VALI range).
