TrueAlert A/V Operation
The 4903 TrueAlert Audible/Visible (A/V) unit (see Table 1) is a wall-mounted
notification appliance that provides an audible and/or visible indication of an alarm
condition when activated from a TrueAlert-compatible control panel of a UL-listed,
Simplex Fire Alarm System. When the notification appliance emits sound and/or
light, it indicates the possibility of an emergency situation that requires your
immediate attention.
The TrueAlert A/V unit is a notification appliance that operates only on a
TrueAlert-compatible Signaling Line Circuit (SLC). The appliance is
supervised via communications with the TrueAlert Addressable Controller
(rather than via conventional appliance supervision).
The A/V unit responds to communication signals over the SLC from a
TrueAlert-compatible panel. Coded messages from the TrueAlert controller turn on
the A/V strobe and horn. The A/V can only be operated through a 4009-9401
TrueAlert Addressable Controller using Simplex TrueAlert Comm Channel
communications.
The A/V horn provides selectable high/low volume sound pressure levels with audible output types of Steady, Temporal, and
March Time (fast/slow). The compatible TrueAlert Addressable Controller or FACP is used to configure the features.
Note: The TrueAlert A/V will not operate on a conventional NAC.
TrueAlert A/Vs are available rated at 15 candela, 75 candela, and 110 candela. Each model is available with a red or white cover.
Table 1 lists the available A/V models.
