The system consists of a Master Control Panel capable of controlling and supervising up to a maximum of 900 Remote Handset zones. Each Remote 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
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.
