Bosch Security Systems B.V. Installation and Operation manual 180110011Aa | V1.1 | 2011.05

1Safety

Prior to installing or operating this product, always read the Important Safety Instructions

which are available as a separate document (F.01U.120.759). These instructions are supplied

together with all equipment that can be connected to the mains supply.

Safety precautions

The battery charger is designed to be connected to the 230 Vac public distribution network.

To avoid any risk of electric shock, all interventions must be carried out with disconnected

mains supply (upstream two-pole circuit-breaker open) and disconnected battery.

Interventions with the equipment switched on are authorized only when it is impossible to

switch the equipment off. The operation must only be performed by qualified personnel.

2.5 Alerts and notice signs

Four types of alerts are used in this manual. The alert type is closely related to the effect that

may be caused if it is not observed. These alerts - from least severe effect to most severe

effect - are:

NOTICE!

Alert containing additional information. Usually, not observing a ‘notice’ does not result in

damage to the equipment or personal injuries.

CAUTION!

The equipment or the property can be damaged, or persons can be lightly injured if the alert is

not observed.

WARNING!

The equipment or the property can be seriously damaged, or persons can be severely injured

if the alert is not observed.

DANGER!

Not observing the alert can lead to severe injuries or death.

3 System Overview

3.1 Application

The PLN-24CH12 (24 Vdc) and the PRS-48CH12 (48 Vdc) battery charger is intended for a

Voice Alarm System. The battery chargers are microprocessor based devices that have been

designed to charge lead-acid batteries (back-up batteries connected to the Voice Alarm

System) and, simultaneously, to provide power to auxiliary applications.

3.2 Short description

The battery charger, which is fully compliant with EN54-4, offers a maximum charge current of

12 A.

The battery charger is two rack units (2 RU) high, and has to be installed in a 19” rack.

3.3 Scope of delivery

The battery charger is packed with the following parts:

– 1x Installation and Operation manual

– 1x Safety instructions

– 1x Mains plug (lockable)

– 6x Main output connector

– 3x Auxiliary output connector

– 1x Contact output connector

– 1x Temperature sensor connector

– 1x Temperature sensor

– 1x Main output fuse (32 A)

– 1x Auxiliary output fuse (5 A)

– 1x Mains fuse (6.3 A for PLN-24CH12) or (8 A for PRS-48CH12)

– 1x Power supply fuse (12.5 A)

– 2x Binding strip (to connect the temperature sensor to the battery cable)

– 4x Screw (for mounting the battery charger into a 19" rack)
