Indicators, Controls and Operations
8.7.4
Non-Latching Supervisory (For Supervisory Circuits)
Activation on these circuits will cause the Circuit Status LED and the amber Common
Supervisory LED to illuminate. The buzzer will sound at fast rate. If the circuit activation is
removed, the Supervisory condition will clear (as long as there are no other Supervisory
conditions in the system) and the Circuit Status LED will turn off.
8.7.5
Latching Supervisory (For Supervisory Devices)
Activation on these circuits will cause the Circuit Status LED and the amber Common
Supervisory LED to illuminate. The buzzer will sound at fast rate. If the circuit activation is
removed, the Supervisory condition will NOT clear.
8.7.6
Abort Switch
When the hazard area is in alarm (pre-discharge) state and the release timer is running, the
activation of the corresponding Abort Switch will pause the releasing timer. The release
process is held while the Abort Switch is pressed. Releasing the Abort Switch will resume the
releasing timer and the corresponding hazard area goes into Alarm (pre-discharge) state
again. The value of the release timer after Abort Switch is released depends on the type of
Abort Delay in the configuration. When the release timer expires, the corresponding releasing
circuit is activated. When the panel is in normal condition, activation of the Abort Switch will
cause a trouble signal and the corresponding zone amber LED turns on at slow flash rate.
8.7.7
Manual Release Switch
Activation of the Manual Release Switch of a hazard area will activate the corresponding
releasing circuit. If the corresponding Manual Release Delay is non-zero, the releasing circuit
will be activate after the Manual Release Delay expires.
8.7.8
Indicating (Signal) Circuits Types
8.7.9
Silenceable Signal
The Silenceable Signal circuit is used for audible devices such as bells and piezo mini-horns
that may be silenced either manually or automatically.
8.7.10 Non-Silenceable Signal
The Non-Silenceable Signal Circuit is used for audible devices such as bells and piezo mini-
horns that may
not
be silenced either manually or automatically. While sounding, these
devices follow the evacuation code pattern that is configured by the user. For more information
on evacuation codes, refer to
Evacuation Codes
below.
8.7.11 Silenceable Strobe
Silenceable strobes will be silenced when the “signal silence” key is pressed.
8.7.12 Non-Silenceable Strobes
Non-Silenceable Strobes will not be silenced when the “signal silence” key is pressed.
