II. TERMINOLOGY
PA Public Address: Voice alarm and safety sound systems.
PSE Power Supply Equipment Power supply in compliance with EN54-16.
VACIE Voice Alarm Control and Indicating Equipment.
EN54-16 Standard for voice alarm and safety systems
Fire detection and fire alarm systems - Part 16: voice alarm control and indicating equipment
Line Basic element that can be selected on a public-address system.
Physically, a line corresponds to the output of an amplifier.
Depending on the output power, a line may have more than one loudspeaker. A discriminant
loudspeaker selection cannot be achieved on the same line.
EOL End of Line: 10-KΩ resistor wired at the end of the line so that the VACIE can test line integrity.
SC/OC Short Circuit/ Open Circuit
AZ Alarm Zone: Set of lines on the system over which the Vocal Alarm is broadcast.
VA Specific measuring technique developed by Bouyer that detects faults on loudspeaker lines.
Re ion Group of alarm zones.
General Call Broadcast on all lines in an alarm zone.
Voice Alarm Evacuation message broadcast.

IV. CAUTION
CAUTION: Risk of electric shock may result following a contact with HP
lines activate.
Make only measurements on speaker lines disconnected from their
amplifiers.
Before disconnecting speaker lines, it is advisable to turn off
amplifiers.
Any electric potential on the line may cause the destruction of the MZ-
4000.

V. OPERATION
URN ON AND OFF
Press the “ON - ” button to power up the device. he following main menu is displayed on the screen:
If the user does not perform any action for a configurable period of time, the device switches off automatically. he user can also
switch off the device by pressing and holding the "ESC" button.
NB: his function is only available from the main menu.
MAIN FUNC IONS
he main menu is used to access the different tester functions.
hese functions are as follows:
•Impedance measurement
•VA measurement
•Audio generator
•Automated line testing with the results saved on the SD card.
•Settings
he status bar at the bottom of the screen displays the date / time and the battery voltage level.
Measurement may become less accurate if the battery voltage is less than 5V.
In this case, the "Low Bat" message is displayed in the lower banner.

IMPEDANCE MEASUREMEN
his function measures the impedance of a line of speakers.
o access this function, use the jog dial (rotary knob) to reach the "Impedance" icon.
After connecting the "+" and "-" terminals of the tester to the line to be measured, press the knob to start measuring. he
measurement is taken at a frequency of 1000Hz.
he device searches for the optimal measuring point to obtain the best accuracy, and until it is reached, the following screen is
displayed:

As soon as the optimum measuring point is reached, the value is displayed in Ohms with its equivalent in Watts for a voltage of
100V RMS.
If the measured value is greater than the upper limit of the tester (10kΩ), the device will display the following screen:
