GENERAL DESCRIPTION

The PS 285 is designed for use as an auxiliary 2-channel

power supply unit, should the main power supply of an

ASL intercom system be insufficient to drive the required

number of stations.

The unit has to be placed in a network in such a way that

it feeds its own group of user stations.

The PS 285 can be used in portable as well as fixed

applications. It uses only 1U of 19" rack space.

The unit is very versatile and ideal for use in applications

where standard microphone cable is available and ease of

set-up is of paramount importance.

MECHANICAL INSTALLATION

A vertical rack space of 1U (1.75", 44mm) is required for

the PS 285. It is not necessary to provide rear support by

extra bracing or shelving.

Adequate ventilation must be provided by allowing

sufficient space around the sides and rear of the unit to

ensure free circulation of air. Forced cooling is not

required.

The intercom line power supply is fully protected and is

capable of safely driving 20 beltpacks or 10 speaker

stations, or a combination of the two, operating at full

power.

Fully electronic switching increases reliability and allows

for remote Mic Mute facility.

ASL has taken great care to ensure that this product

reaches you in flawless condition.

After unpacking the unit please inspect for any physical

damage to the unit, and retain the shipping carton and

relevant packing materials for use should the unit need

returning.

If any damage has occurred, please notify your dealer

immediately so that a written claim can be initiated.

Please also refer to the guarantee section of this manual.

The power supply regulator is mounted on the rear of the

unit, and after a period of time it will feel hot to the touch.

This is quite normal, and should be no cause for alarm.
