Line Supervisory

LS-3010-AS

TOA LS-3010 Line Supervisory is a highly reliable and efficient 10 channels line supervisory for measuring or monitoring the impedance of each speaker line. The status of each speaker line in normal, open or short condition is easily identified by the LED indicators.

10 channels input from amplifier, 10 channels output to speaker line
10 channels attenuator bypass control and 1 fault control
Speaker line fault detection in individual zone. Normal (Green), Open (Orange), Short (Red) LED indicators
1W to 500W (20 Ω to 10 kΩ measurement range)
Ability to schedule monitoring of speaker line at 1min, 1hour, 12hours and 24hours
Lamp test with buzzer
Short Circuit speaker line isolation
Ability to detect speaker line branching with impedance measuring function

The speaker line supervisory panel is a highly efficient 10 channels speaker line monitoring system. It is able to detect individual speaker line impedance condition that displays status by indicating short - red, open – yellow, normal -green on the 10 LEDs. The LED indicates measurement and shown no speaker is connected. The impedance measured from 20Ω to 10KΩ. Each channel can handle speaker load of 1W to 500W. In the case of speaker line is short circuit, the output will isolate and protect the amplifier from damage. There are 10 individual dry contacts control out that allow the attenuator to be bypass during speaker measurement. A fault out allows to connect to other monitoring device.

The front panel shall include time schedule checks of 1min, 1 hour, 12 hours, 24 hours and OFF. There are buttons for lamp test, calibrate, measure, Buzzer bypass and reset. Front panel with a power indicator, 10 individuals bypass channel OFF switch that allow speaker line check to be bypass.

The speaker line supervisory panel shall be capable of operation from a 24VDC power at 1 Ampere.

Dimensions (W x H x D) shall be 420 x 44 x 320 mm. Net weight shall be 3.2 kg.

The front panel finish and material shall be black powder coating, case is black finish and material shall be steel plate. Its shall be rack mounted and occupy 1U size standard 19" rack spaces.

The speaker line supervisory panel shall be TOA model LS-3010-AS.
