BS- 660/A
GENERAL
The user have to read carefully the following instructions, in order to be properly informed and
keep them for future use.
The
BS-
660/A is a conventional heat detector which integrates
the function of rate-of-rise
o
heat detection.
The detector transitions to alarm state when the temperature reaches 57 C.
o
Also, the detector transitions to alarm state when the temperature rises suddenly by 32 C
regardless of the initial temperature at the beginning of the sudden rise event.
They are composed by two parts. A plastic base which is placed on the ceiling and the main
body of the detector which fits on the plastic base with a simple rotation to the right. The
o
detectors have a 360 visible led and a remote led driver which are light up constantly in case
of detection of fire, till cancelled from the panel.
They are turned off only when a reset
command is given from the panel. The indicator led blinks every
6
sec indicating the normal
function.
.
INSTALLATION
The detectors should be placed in the ceiling in visible points without side obstacles, away
from places that are barely ventilated or with strong air currents and water vapor. Each
2
detector covers an area of 50 m while the distance between two detectors should not be
more than 15m. Also, they must be placed at least 50 cm away from fluorescent lamps. Cable
diameter should be from
. to .
MAINTENANCE & FUNCTIONAL TESTING
The detector has fault diagnosis function, which automatically informs you through the
onboard LED when detector replacement is required. The indication LED blinks every 7
seconds. In normal operation it blinks 1 time and if there is a failure it blinks 3 times. These
