General Description
The MDL Module is designed to work with the SpectrAlert
series of notification appliances to provide a means of
synchronizing the temporal-coded horns and chimes, syn-
chronizing the one-second flash timing of the strobe, and
silencing the horns and chimes of the horn/strobe and
chime/strobes 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
input(s) 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 direct con-
nection between the zone input and the zone output 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 or chimes 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
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 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.

CAUTION
When MDL module is used, supply volt-
age range at 12 volts: 9 to 17.5 VDC; at 24
volts: 17 to 33 VDC

Synchronize SpectrAlert Horns, Chimes and Strobes
• Each module can power two 3-amp circuits wired in
class B or one 3-amp circuit powered as Class A.
•Each module will synchronize 2 zones.
• Additional modules can be added and may be syn-
chronized to all other modules by interconnecting the
“slave” input and output terminals between modules.
CAUTION
Horn control wiring must be contained within common en-
closure of module.
CAUTION
Slave Out – Slave In wiring must be contained within either
the common enclosure of modules or enclosures within 20
feet of each other with wiring inside conduit.
CAUTION
If Zone 1 input is not powered or fails during alarm, the
notification devices attached to the Zone 2 output will not
be powered.
Controlling Sounder On/Off Over 2-Wires Using Mod-
ule Horn Control
•Connect the current source to the horn or chime control
input. If a zone output is used for the source, you must
use an EOL on the horn control input terminal.
• When multiple modules are used, the horn or chime
control circuits can be wired in parallel. If wired in par-
allel and a zone output is used from panel, use an EOL
on the last module for supervision.
CAUTION
Horn/chime control wiring must be contained within com-
mon enclosure of module.
CAUTION
Slave Out – Slave In wiring must be contained within either
the common enclosure of modules or enclosures within 20
feet of each other with wiring inside conduit.
CAUTION
If Zone 1 input is not powered or fails during alarm, the
notification devices attached to the Zone 2 output will not
be powered.
Special Considerations
A latching relay contact is provided in case the synchro-
nizing signal to the notification devices is interrupted. The
output can be wired so that a trouble signal will be annun-
ciated at the panel. If the synchronization pulse fails in the
MDL module, the strobes will shut off.

NOTE: Horn/chime control must be powered for horn/

NOTE: SpectrAlert horn-only/chime-only and horn/strobe

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).
CAUTION
Strobes cannot be used on a module providing temporal coding
to horns. Strobes must be wired for independent operation.
NOTE: Temporal jumper should be inserted across both
pins only on non-SpectrAlert products that are to be pow-
ered for temporal sound output.

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.
Horns will be Temporal
coded and in sync.

Three-Year Limited Warranty
System Sensor warrants its enclosed product to be free from defects in materi-
als and workmanship under normal use and service for a period of three years
from date of manufacture. System Sensor makes no other express warranty
for the enclosed product. No agent, representative, dealer, or employee of the
Company has the authority to increase or alter the obligations or limitations
of this Warranty. The Company’s obligation of this Warranty shall be limited
to the replacement of any part of the product which is found to be defective
in materials or workmanship under normal use and service during the three
year period commencing with the date of manufacture. After phoning System
Sensor’s toll free number 800-SENSOR2 (736-7672) for a Return Authorization
number, send defective units postage prepaid to: System Sensor, Returns
Department, RA #__________, 3825 Ohio Avenue, St. Charles, IL 60174. Please
include a note describing the malfunction and suspected cause of failure.
The Company shall not be obligated to replace units which are found to be
defective because of damage, unreasonable use, modifications, or alterations
occurring after the date of manufacture. In no case shall the Company be
liable for any consequential or incidental damages for breach of this or any
other Warranty, expressed or implied whatsoever, even if the loss or damage
is caused by the Company’s negligence or fault. Some states do not allow the
exclusion or limitation of incidental or consequential damages, so the above
limitation or exclusion may not apply to you. This Warranty gives you specific
legal rights, and you may also have other rights which vary from state to state.
The sounder and/or strobe will not work without power. The sounder/strobe
gets its power from the fire/security panel monitoring the alarm system. If power
is cut off for any reason, the sounder/strobe will not provide the desired audio or
visual warning.
The sounder may not be heard. The loudness of the sounder meets (or exceeds)
current Underwriters Laboratories’ standards. However, the sounder may not alert
a sound sleeper or one who has recently used drugs or has been drinking alcoholic
beverages. The sounder may not be heard if it is placed on a different floor from the
person in hazard or if placed too far away to be heard over the ambient noise such
as traffic, air conditioners, machinery or music appliances that may prevent alert
persons from hearing the alarm. The sounder may not be heard by persons who are
hearing impaired.
The signal strobe may not be seen. The electronic visual warning signal uses an
extremely reliable xenon flash tube. It flashes at least once every three seconds and
exceeds current Underwriters Laboratories standards for private mode viewing. The
visual warning signal is suitable for direct viewing and must be installed within an
area where it can be seen by building occupants. The strobe must not be installed in
direct sunlight or areas of high light intensity (over 60 foot candles) where the visual
flash might be disregarded or not seen. The strobe may not be seen by the visually
impaired and is not intended to meet American Disabilities Act (ADA) requirements.
The signal strobe may cause seizures. Individuals who have positive photic re-
sponse to visual stimuli with seizures, such as persons with epilepsy, should avoid
prolonged exposure to environments in which strobe signals, including this strobe,
are activated.
The signal strobe cannot operate from coded power supplies. Coded power sup-
plies produce interrupted power. The strobe must have an uninterrupted source of dc
power in order to operate correctly. System Sensor recommends that the sounder and
signal strobe always be used in combination so that the risks from any of the above
limitations are minimized.
