FIRERAY Projected Range

8.2.1 FIRERAY

2000

The FIRERAY 2000 a Projected Optical Beam Smoke Detector.

Its greatest attribute is its small dimension combined with its cosmetic appearance, making the
FIRERAY 2000 the Optical Beam Smoke Detector of choice for aesthetically demanding applications
(historic buildings, museums) and environments prone to reflections.

8.2.2 Accessories

The following accessories can be supplied with FIRERAY 2000

Obscuration Test Filter

To perform a sensitivity test of 25% to 100% obscuration

Alignment Tool

To assist in the alignment of the Receiver at the installed location. This allows one person to set up,
test and maintain the FIRERAY 2000

Protective Cage

To protect the FIRERAY 2000 from damage leading to misalignment and fault alarms.
