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.

ZONE 1 INPUT

FACP before anything will work. This also supplies voltage to Zone 1 output.

This input powers the MDL Module. This input must have voltage present from the

ZONE 2 INPUT

powered, the notification devices attached to the Zone 2 output will not be allowed.

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.

This input enables the horns on the SpectrAlert notification appliances. Voltage

This input only supplies voltage to Zone 2 output.

NOTE:

If Zone 1 input is not

Horns Silenced Over Two-Wire Circuit

1) Any mix of SpectrAlert horns/strobes or strobe-only devices is

acceptable.

2) Horn Control connects to interruptible power source.

NOTES:

1)

Any mix of SpectrAlert horn/strobe, strobe-

only, or horn-only devices is allowable for

Zone 1.

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.
