NOTE: The MDL Module is factory set with the sync error
contacts in the open state. These contacts may close during
shipping. Approximately two seconds after power-up, these
contacts will open.
NOTE: This contact could be wired to a separate monitor-
ing input at FACP.

NOTE: If zone 1 output of module is connected to strobes,
chime/strobes or horn/strobes, zone 1 input supply power
must be continuous for proper operation.

NOTE: Horn/chime control must be powered for horn/
strobes to operate the horn portion.
NOTE: SpectrAlert horn-only/chime-only and horn/strobe
or chime/strobe devices must be set non-temporal for
multi-code sourcing.
Temporal Coding on horns that produce a continuous
tone (Non-SpectrAlert Horns)
See Figure 6
• 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 independent operation.
A0181-00
NOTE: Temporal jumper should be inserted across both
pins only on non-SpectrAlert products that are to be pow-
ered for temporal sound output.
Figure 6:
NOTE: If zone 1 output of module is connected to strobes or
horn/strobes, or chime/strobes zone 1 input supply power
must be continuous for proper operation.
