Operation
A second stage alarm (general alarm) when the panel is already in alarm causes the following:
• The buzzer sounds steadily
• All non-disconnected signals are activated at the evacuation rate
• If the Signal Silence LED is on, it turns off and the Auto Signal Silence timer, if
configured, is restarted
• The General Alarm Cancel LED if on, turns off
Alarm inputs are latching: they remain active until system reset.
11.3 Pre-Signal Operation
To configure the panel for pre-signal, all alarm inputs must be correlated to one NAC circuit
that is wired to a Notification Appliance in the Control Room that is constantly monitored by an
Operator. Using the FX-2000 Configurator, “Subsequent Alarm” in “Common System Status”
must be correlated to turn on the Remaining NAC circuits in the system. To confirm the alarm
(i.e. subsequent alarm) the operator can press the “General Alarm” button on the panel or
activate a Manual Station in the Control Room.
11.4 UUKL feature
The UUKL Feature on the FX-2000 Configurator is used only in conjunction with the FDG-008
and FDX-008W Fan Damper Controller modules.
In each UUKL relay/equipment set, the user could set up the “Any of” operation. If this option
is selected, the panel will still go into alarm directly if any detector is tripped. The only
difference is that if a relay which is part of the smoke control is configured for “any of”
operation, that relay will only activate after a configurable number of detectors are active.
This operation is meant to be used in an atrium where multiple detector operation is required
to start the smoke control operation but the signaling within the building is based upon the first
detector to activate.
For complete details refer to manual LT-966.
11.5 Output Circuit Delay Operation
The relay function associated with an alarm initiating circuit may be delayed. There is a Output
Delay timer associated with this, refer to Table below. This is programmed using the FX-2000
Note: If the system is configured for correlations, any second stage / general alarm
condition activates all NAC circuits whether they are correlated or not.
Note: Pre-Signal is not permitted to be used in Canada.
