EDS - RK90R - OPTICAL BEAM SMOKE DETECTOR - USER GUIDE

GENERAL

The RK90R detector is a newly-conceived microprocessor linear smoke detector, that bases its
working concept on the interaction between the smoke present in a in a room and an infrared beam
emitted by a transmitter and reflected by an optical reflector (fig.1).

The normal installation consists in mounting the detector on a wall of the room to be protected and in
fixing the FX reflector (FX01, FX02, FX03 depending on the distance) on the opposite wall.

For a correct installation, we recommend to read and follow our instructions carefully.

The excellent working results of the device will widely compensate the time spent reading these
instructions.

1 - QUALIFIED PERSONNEL

All the operations of installation, setup, startup, maintenance and verifications of operation of the
RK90R detector must only be performed by qualified personnell.

These people are qualified for their experience, specialization courses, knowledge of the current
standards and of the technical specifications, features and usage method of the product.

These people therefore are able to avoid errors or damages and assure an optimal functioning of the
product.

2 - RELEVANT STANDARDS

2.1

- For the installation in European Community countries you must follow the EC standard EN54-

14 (Fire detection and fire alarm systems).

In extraeuropean countries you must respect the relevant international and national standards.
