Application Examples
Temporal Coding on Multi-Alert and PA400
(Non-SpectrAlert Horns)
• Program module to provide temporal coding by inserting
jumper plug per instructions.
• Connect only sounders producing a continuous tone to
the module zone output(s).
Strobes cannot be used on a
module providing temporal
coding to horns! Strobes must be wired for inde-
pendent operation.
NOTE: Temporal jumper should be inserted across both pins
only on non-SpectrAlert products that are to be powered for
temporal sound output.
Synchronize SpectrAlert Horns and Strobes
ZONE 1 INPUT
This input powers the MDL Module. This input must have voltage present from the
FACP before anything will work. This also supplies voltage to Zone 1 output.
ZONE 2 INPUT
This input only supplies voltage to Zone 2 output. NOTE: If Zone 1 input is not
powered, the notification devices attached to the Zone 2 output will not be allowed.
HORN CONTROL
This input enables the horns on the SpectrAlert notification appliances. Voltage
present means horns are enabled. No voltage present means horns are disabled.
SLAVE IN Connects to Master MDL Module slave out.
SLAVE OUT Connects to Slave MDL slave in.
Synchronize SpectrAlert
Horns and Strobes
• Each module can power two
three-amp circuits wired in
Class B, or one three-amp
circuit powered as Class A.
• Each module will synchronize
two zones.
• Additional modules can be
added and may be synchro-
nized to all other modules by
interconnecting the “slave”
input and output terminals
between modules.
