Vanguard V25-70 Series User manual

The Vanguard V25-70 Series Two-Way Emergency Voice Communication System is designed to
provide reliable and easy-to-use, communication for firefighters during an emergency.
The system consists of a Master Control Panel capable of controlling and supervising up to a maximum
of 900 emote Handset zones. Each emote Handset is wired to the Master Control Panel on a point to
point configuration. Such configuration prevents cable fault in one handset from affecting the other
handsets in the system.
Individual control buttons makes the system very easy to use as most control functions require only one
press operation. Individual LED status indicators provide operator with a quick overview of the system
status at a glance.
A wide range of system fault monitoring circuits and fault indicators are built into the system. Handsets
and cables are supervised for open and short circuit faults. Power supply unit and battery charger are
protected by fuses and supervised for faults. A one press Lamp Test button checks for faulty indicators.
The built-in battery enables the system to function without interruption even when mains supply fails. After
a mains failure, a boost charge facility allows the drained battery to be recharged to full capacity in a
shorter time. A digital voltmeter and ammeter provides accurate and easy to read system voltage and
current levels.
An optional Cassette Interface Module (complete with cassette recorder) is available to record all voice
transmission through the system. The recording can be started automatically whenever the fire alarm
system is activated.
The system meets the requirement of Singapore Standard CP25: Code Of Practice For Emergency Voice
Communication System in Buildings.

OPERATION
Master Control Panel Calling Remote Handsets
1. aising the Master Handset of the Master Control Panel enables every zone “SELECT” button.
2. Pressing the “SELECT” button of the required zone will cause the selected zone’s “CALL” indicator to flash.
3. A distinctive audible call signal at the selected emote Handset will sound.
4. aising the called emote Handset off its cradle will silence the audible call signal.
5. The flashing “CALL” indicator of the Master Control Panel will turn steady.
6. Communication link is now established.
Privacy Mode
The Privacy Mode facility allows private conversation between the Master Handset and any selected emote Handsets. emote
Handsets which have not been selected will receive a “busy” tone. The system is on Privacy Mode by default.
1. When the Master Handset is raised, the “P IVACY LINE ON” indicator lights up indicating that the system is in Privacy Mode.
2. A “busy” tone will be heard on any of the raised handsets. The “CALL” indicators of the raised handsets will flash.
3. Pressing the “SELECT” button of any raised handset zone will establish communication with it. The flashing “CALL” indicator of
the selected handset zone will turn steady.
4. Additional callers can be added into the communication channel by pressing its “SELECT” button.
5. To disable Privacy Mode and allow all callers to participate in the communication, press the “P IVACY MODE” button. The
“P IVACY LINE ON” indicator turns off. The system is now in conference mode and all new callers will be able to participate in
the conversation.
