1 Overview
The BPC65 is a 19” rack mounting self-contained 24 V DC battery backup system for use with ASL Voice
Alarm systems. It is designed to comply with EN 54-16, ISO 7240-16 and BS 5839-8.
The BPC65 is for use on 230 V AC mains supply and provides 65Ah of battery capacity with a 3.25 A recharge
rate. The battery system features temperature compensation of the charge voltage to maximise battery
life. The unit is fully monitored to the requirements of EN 54-4 and BS 5839-8 and provide fault-reporting
outputs for direct connection to the Voice Alarm Router1.
Eight BDIST 25 A and two BDIST 3 A outputs are provided. The BDIST (Battery Distribution) comprises all of
the required connectors and miniature circuit breakers. The 25 A outputs are normally used for connecting
ASL Amplifier Mainframes2. The 3 A outputs are used with low current 24 V DC powered equipment such as
the ASL Routers. Various battery power distribution cable assemblies are available from ASL for
connecting the relevant equipment.
The BPC65 battery backup system comprises one charger tray, one battery tray and two 12 V batteries3;
see Figure 1 (page 4). The battery backup system requires 8U rack space. The charger tray is designed to fit
into racks with 600 mm or 800 mm depth. The battery tray is available for a variety of 19” rack types. As
additional rack types are regularly added, check with ASL for current availability on any given rack type.
The MDIST (Mains Distribution) provides all of the required components for mains distribution from a
32 A rack input to the required number of outputs. All outputs are 10 A IEC320-IEC320 leads which are
primarily designed for connection to an ASL Amplifier Mainframe but are also suitable for other equipment.

A variety of factors need to be carefully considered when designing battery backup systems
for Voice Alarm applications. To assist in this process, a battery requirements calculator is
available from the ASL’s website at www.asl-control.co.uk.
