BDESCRIPTION
SURVEILLANCE BOARD SV—200MA
Jesign ned to be built in the VWM-2120/-2240 amplifiers, the SV-200MA permits monitoring of individual
speaker line or power amplifier failures for status indication.
BSPECIFICATIONS
Power Source 24 V DC
Current Consumption 120 mA
Control Input and Output
Input: No-voltage make contact input, open voltage: 3.3 V DC,
short—circuit current: 1 mA or less
(1) Speaker line initial setting activation signal
(2) Speaker line surveillance activation signal
Output: Open collector output, withstand voltage: 30 V DC,
control current: 10 mA or less
(1) Monitoring short or open of individual speaker line (zone 1 — 5)
(2) Ground fault (insulation resistance: 50 kQ or less)
(3) Power amplifier failures
Input/Output
Input: No-voltage make contact input, open voltage: 24 V DC,
short—circuit current: 60 mA or less
Output: Open collector output, withstand voltage: 24 V DC (used with VM 24 V DC output),
control current: 20 mA or less
(1) Speaker Zone information/selection
(2) Power amplifier fault link
Connector: D—sub connector (25—pin, female)
Failure Detection
Power amplifier failure: 20 kHz pilot tone detection
Speaker line failure: 40 Hz impedance detection (Detectable minimum load: 5 W)
Speaker Line Surveillance
Speaker lines are automatically monitored at set time intervals
Set Time
(10 — 60 min, at 10 min intervals)
Operating Temperature
0 °C to +50 °C
Operating Humidity
90 % RH or less (must be free from dew condition)

Weight 140 q
Accessory Flat cable
BAPPEARANCE
= Caution: about combination with SV-200MA and
UL-adaptive speaker
The following UL-adaptive speakers can't use,
because there is a possibilities to cause
short circuit false detection.
BS—680U
CS—64U/154U/304U
PC-580RU/580RVU
SC-630U
Please contact your nearest TOA dealer about
a UL-adaptive speaker which will be added
from now on.
