Gamewell-FCI MDLW Mdl, mdlw sync modules for spectralert sery Datasheet

MDL, MDLW Sync Modules
for SpectrAlert® Series
Specifications
Voltage range: DC or full-waverectified; 11 to 30 volts. NOTE:
Supply voltage range at 12 volts, 11
to 17 VDC; at 24 volts, 21 to 30 VDC.
Maximum load on loop: 3 amps.
Current: See table below.
Application Flexibility.
The Sync•CircuitTM module
is designed to power and
synchronize either two 3amp circuits wired in Class
B or one 3-amp circuit powered as Class A. Should
more than two zones require
synchronization, additional
modules can be added by
interconnecting the “slave”
input and output terminals
between modules.
The MDL Module
Additional Capabilities. The Sync•CircuitTM module is also designed to generate temporal 3 tone for System Sensor’s Multi-AlertTM and PA400 Mini-AlertTM
sounders. Existing installations can be upgraded to comply with NFPA 72.
Module Configuration
Each MDL module has the capability of connecting two Style Y (Class B) circuits or one Style Z (Class A) circuit.
The NAC 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 direct connection 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 (zones 1 & 2) 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 Application
Examples).
Special Considerations
NOTE: The MDL Module is factory-set with the trouble contacts in the open
state. These contacts may close during shipping. Approximately two seconds after power-up, these contacts will open.

The Sync•CircuitTM module
synchronizes SpectrAlert®
strobes at 1 Hz and horns
at temporal 3 over a single
pair of wires. Patented module technology also allows
the silencing of horns on
horn/strobe models over a
single pair of wires.

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 independent 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
This input powers the MDL Module. This input must have voltage present from the
ZONE 1 INPUT FACP before anything will work. This also supplies voltage to Zone 1 output.
This input only supplies voltage to Zone 2 output. NOTE: If Zone 1 input is not
ZONE 2 INPUT powered, the notification devices attached to the Zone 2 output will not be allowed.
This input enables the horns on the SpectrAlert notification appliances. Voltage
HORN CONTROL 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 synchronized to all other modules by
interconnecting the “slave”
input and output terminals
between modules.

Controlling Sounder On/Off Over Two Wires Using Module Horn Control
• Connect the current source to the horn 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 control circuits can be wired in parallel. If wired in parallel and a zone
output is used from panel, use an EOL on the last module for supervision.
This input powers the MDL Module. This input must have voltage present from the
ZONE 1 INPUT FACP before anything will work. This also supplies voltage to Zone 1 output.
This input only supplies voltage to Zone 2 output. NOTE: If Zone 1 input is not
ZONE 2 INPUT powered, the notification devices attached to the Zone 2 output will not be allowed.
This input enables the horns on the SpectrAlert notification appliances. Voltage
HORN CONTROL 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.
Horns Silenced Over Two-Wire Circuit
NOTES:
1) Any mix of SpectrAlert horns/strobes or strobe-only devices is
acceptable.
1) Any mix of SpectrAlert horn/strobe, strobeonly, or horn-only devices is allowable for
Zone 1.
2) Horn Control connects to interruptible power source.

2) No devices or horn-only are allowed on Zone
2. If no devices are installed on Zone 2,
terminate EOL resistor at horn control
terminal.

Limitations of Horns/Strobes
The horn and/or strobe will not work without power. The horn/strobe gets its power from the fire/security panel monitoring the
alarm system. If power is cut off for any reason, the horn/strobe will not provide the desired audio or visual warning.
The horn may not be heard. The loudness of the horn meets (or exceeds) current Underwriters’ Laboratories standards. However, the horn may not alert a sound sleeper or one who has recently used drugs or has been drinking alcoholic beverages. The
horn 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 horn 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 footcandles) 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 response 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 supplies produce interrupted power. The strobe
must have an uninterrupted source of DC power in order to operate correctly. System Sensor recommends that the horn and
signal strobe always be used in combination so that the risks from any of the above limitations are minimized.
