Note: All TrueAlert Addressable Controller channels are reported as
failed while the diagnostics are being run.
Whenever a TrueAlert channel is in a diagnostics mode, a diagnostics trouble is
displayed on the Operator Interface Panel. A TrueAlert channel will be in such a
diagnostics mode any time it has an LED lit for diagnostics reasons or any time
the channel is in a silent test or individual appliance test mode.
Note: This feature only works when “LEDs flash when polled” is NOT
selected as an option in the Programmer.
The TrueAlert channel supervises appliances by polling them. In the event of a
appliance not responding, the system reports an appliance missing trouble. The
4100 provides the capability of identifying the channel, the appliance address,
and the labels for the appliance at the operator interface. To aid in finding the
appliance, the 4100/4020 has the capability of turning on all of the LEDs on a
TrueAlert Addressable Controller via the Operator Interface Panel. This allows
the technician to go out into the building and look for the appliance without a lit
LED. The operation to turn on the LEDs does not require you to hold a button
down. However, it will not allow you to leave the screen that activates the LEDs
until they are restored to normal mode.
To activate
all Appliance LEDs on all TrueAlert Controller Channels, log on the
4100/4020 at the appropriate Access Level. On the Operator Interface Panel, go
to the TrueAlert appliance function screen and turn on the appliance LEDs on
the TrueAlert Addressable Controller. Verify that all of the appliance LEDs
assigned to the TrueAlert Addressable Controller turn on. (The 4100/4020
display will remained locked onto this screen for eight hours or until you turn off
the LEDs.) From the Operator Interface Panel display under the TrueAlert
appliance function screen enable turn off the appliance LED’s on the TrueAlert
Addressable Controller. If more than one TrueAlert Addressable Controller is
connected to the system repeat the above procedure on the remaining
Addressable Controllers.
It is often disruptive to test NACs in an occupied building. To minimize this
disruption, the TrueAlert peripherals support a single appliance test mode (also
known as the Manual Real Appliance Test) that makes a given notification
appliance report its address and emits an alarm.
To initiate the Manual Real Appliance Test, place a magnet on the appropriate
area of the notification appliance. The appliance LED emits one long flash
denoting the test acknowledge signal, and then another long flash denoting the
first digit (always zero) of the appliance address. The LED then flashes one to
six times to denote the second digit of the address, pauses, and flashes one to
nine times to indicate the third digit of the address. A zero is always indicated by
one long flash. After the LED flashes, the appliance goes into alarm for two to
three seconds (the audible sounds and the visual flashes). During the test
Trouble Pseudo P230 indicates a trouble: “Device Test Active.”
