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

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

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.
