10. SURVEILLANCE
10.1. What Is the Surveillance Function?
The surveillance function continually monitors operating conditions for each piece of equipment in the system,
operations between equipment components, connections and communications between equipment
components, power supply conditions and other important component parts and points extending from input to
output. If malfunctions or cable breakage is detected, details of such irregularities* are displayed on the VM-
3360VA or VM-3240VA’s LCD. At the same time, the communications failure indicator or failure indicator on
the system equipment flashes to alert the system operator to such irregularities along with a buzzer tone.
The setting software is used to set surveillance time intervals, component parts to be monitored and
subsequent operations when a failure is detected. (Refer to "Surveillance Settings" in the separate software
instruction manual.)
Detected failures are recorded in the VM-3360VA or VM-3240VA’s log, and the recorded log can be confirmed
using the setting software. (Refer to "Log Display" in the separate software instruction manual.)
* For LCD failure display, refer to page 60 .
10.2. How to Use the Surveillance Function
Be sure to perform the following settings to enable the surveillance function. If not performed, the surveillance
function cannot be used.
• Initialize surveillance settings using the setting menu displayed on the VM-3360VA or VM-3240VA’s LCD.
(Refer to
"Surveillance Settings" on page 84 .)
Note
Be sure to perform this initialization after completing the system installation and connections.
• Use the setting software to set the surveillance function. (Refer to "Surveillance Settings" in the separate
software instruction manual.)
10.3. Monitored VM-3000 System Components
Shown below are the monitored component parts and points:
• VM-3360VA or VM-3240VA
• Automatic emergency announcement
• Expansion amplifier (VM-3240E or VM-3360E)
• Emergency remote microphone (RM-300MF)
• Battery
• Speaker (short or open circuit)
• Speaker (ground fault)
• Charging device (VX-2000DS)
• Emergency control terminal
• General-use remote microphone (RM-200M)
• Extension amplifier (VP-2241 or VP-2421)
• Standby amplifier (VP-2241 or VP-2421)
Using the setting software, enable or disable settings individually for each of the above items. (Refer to
"Surveillance Settings" in the separate software instruction manual.)
Tip
Each of the above items can be registered into up to 64 groups only when all the versions of VM-3000VA
firmware, VM-3000E firmware, and VM-3000 Setting Software are 2.00 or later. Each group can be assigned
to the RM-300MF's key, which functions as a failure indicator. (Refer to "RM-300MF settings" in "Event
Settings" in the separate software instruction manual.)
