COMPACT VOICE ALARM SYSTEM
SERVICE MANUAL
7.4 Preparing sound system for VAS application
Cabinet assembly
Carefully mark loudspeaker line cables, control cables and power cables. Upon routing the cables provide at least 3 m of margin,
measured from the floor. Anticipate empty service space behind the cabinet (at least 50 cm from the wall). Make sure there is
a gap between the back of the cabinet and the wall.
Messages recorded on memory cards
Define content, language and type of recorded messages on memory cards. (Emergency messages should suit the building and
be confirmed by the Fire Marshal). To record messages, please contact Autronica employee who is responsible for VAS start-up.
Emergency messages:
»
EVACUATION
– potential life hazard requiring evacuation – the message instructs all inhabitants to leave
the building immediately,
» WARNING – situation in which danger is imminent and requires warning during evacuation,
» CANCELLATION – information that the alarm has been cancelled and there is no danger on the site,
»
NO HAZARDS
– operational messages, e.g. system testing.
Fire scenario and control between FACIE and VAS
Please prepare a fire scenario which involves an algorithm of cooperation between SAP and VAS systems. (This algorithm
should be accepted by the Fire Marshal). Make sure that a sufficient number of cable connections is made between the
FACIE fire signalling central unit and the VAS cabinet to allow triggering of the evacuation message and reporting error state.
When connecting the FACIE central unit to VAS, fire resistant cables with the rating of at least PH30 must be used. As for control
algorithm, please consult Autronica employee responsible for VAS start-up.
Loudspeaker lines
Please check if the loudspeaker lines have been routed in accordance with the blueprint the number of loudspeakers per sin-
gle line, selection of the correct power on speaker transformers, proper line description compliant with the blueprint). Use the
meter (e.g. ohmmeter or multimeter) to check for short-circuits between loudspeaker line and earthed elements. Next, check for
short-circuits or open-circuits between loudspeaker line wires.
c
While assembling loudspeakers, the wires must be connected to the tap of the speaker transformer corresponding to the
correct power as specified in the blueprint. Incorrect power setting can lead to amplifier overload. In the process of system
startup, it causes unwanted time and resource loss.
Power supply
The AutroVoice miniVES units accept Single-phase 230 V AC power. While connecting the power supply, make sure that each unit
is provided with a separate circuit and choose proper means of protection.
The cable supplying the AutroVoice miniVES unit with current should bypass the site’s main power switch. (Use at least 3x 1.5 fire
resistant cable with PH90 rating). The power cord must be led to the target place where VAS cabinet is assembled. The cabinet
power supply circuit must be protected with a residual current device.
