General Description
The MDL Module is designed to work with the SpectrAlert
series of horns, strobes, and horn/strobes to provide a
means of synchronizing the Temporal-coded horns, syn-
chronizing the one-second flash timing of the strobe, and
silencing the horns of the horn/strobe combination over a
two-wire circuit while leaving the strobes active.
NOTICE: This manual shall be left with the owner/user of
this equipment.
Module Configuration
Each MDL module has the capability of connecting two
Style Y (Class B) circuits or one Style Z (Class A) circuit.
The zone output(s) from the panel are connected to the
zone inputs of the MDL module and the zone output(s)
from the MDL module are connected to the notification
loop(s). Supervision is accomplished in the module by a di-
rect connection between the zone input and the zone out-
put of each of the two zone circuits connected to the
normal end-of-line device. The FACP "sees" the EOL device
through the MDL module. When either or both outputs
from the module are wired to the SpectrAlert products, the
horns and strobes in both zones will be synchronized.

The MDL module can be configured so that more than two
zones can be synchronized by the interconnection of the
slave input and output (see Figures 1 and 2).
Zone 1 Input: This input powers the MDL module. This input
must have voltage present from the FACP be-
fore anything will work. This also supplies volt-
age to Zone 1 output.
Zone 2 Input: This input only supplies voltage to Zone 2 out-
put. Note: If Zone 1 input is not powered, the
notification devices attached to the Zone 2 out-
put will not be powered.
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.
