General Description
The OSI- RIE- xx is a long range projected beam smoke imaging detector
designed to provide open area protection. It is to be used with listed (UL,
EN54 , etc.). It is to be powered from a CE Certified AC/DC Power
converters to be in compliance for CE certification. The detector consists of a
transmitter/receiver unit and a reflector. Smoke entering the area between the
transmitter/receiver and reflector causes a reduction in signal. When the
obscuration
reaches
the
alarm
threshold
(automatically
set
at
the
transmitter/receiver unit), the detector generates an alarm signal. Complete
blockage of the beam causes a trouble signal. Slow changes in obscuration due
to a build-up of dirt or dust on the lens of the detector are compensated for by
a Microcontroller that continuously monitors the signal strength and
periodically updates the alarm and trouble thresholds. When the self-
compensation circuit reaches its limit, the detector generates a trouble signal,
indicating the need for service.
Three LEDs on the detector indicate the current status: a red LED for alarm,
a yellow LED for trouble, and a blinking green LED for standby operation.
Note:
The panel controls the status of the red and green LEDs.
The alarm LED can be latched and can be reset by a FACP command.
The yellow LED will blink in specific patterns to provide a diagnostic aid
when diagnosing the cause of a trouble signal. Trouble signals automatically
reset upon removing the cause of trouble. Red and yellow LEDs can be
remotely connected to the remote Alarm and Trouble outputs. These outputs
mimic the functions of the detector’s red and yellow LEDs.
After commissioning the 4 arrows will indicate the level of automatically set
sensitivity.
Special Applications
Due to the inherent capabilities of projected type beam detectors they are
often installed in locations where spot-type detection is impractical. Projected
type beam smoke detectors are ideally suited for environmental conditions that
might include high ceilings or areas with difficult access to the ceiling. Often
these conditions present special problems for the installation of spot- type
detectors and even greater problems for their proper maintenance. Due to the
inherent flexibility of mounting locations and large coverage area of projected
type beam detectors often the conditions above can be addressed or
minimized. Some examples of applications for beam detectors might include
aircraft hangars, cold storage warehouses, shipping warehouses, enclosed
parking facilities, sporting arenas and stadiums or concert halls. Some of these
environments might be considered not suitable for spot-type smoke detectors.
Before installing the transmitter/receiver unit or reflector in these types of
applications special consideration should be given to ensure proper operation
of the beam detector. The beam detector should not be installed in
environments where heavy condensation or icing is likely. Condensation or
icing of the reflector surface or the outer surface of the transmitter/receiver
unit will obscure the light beam resulting in a nuisance alarm. If elevated
humidity levels and rapidly changing temperatures can be expected then
condensation will likely form and the application should not be considered
acceptable for the beam detector.
In environments where a mild condensation is expected, the standard on-board
lens heaters can be initiated by activating the heating switch located in the
detector.
The beam detector should not be installed in locations where the
transmitter/receiver unit, the reflector, or the optical pathway between them
may be exposed to outdoor conditions such as rain, snow, sleet, or fog.
These conditions will impair the proper operation of the detector and must be
avoided.
Approved Accessories
The following accessories can be purchased separately for use with this beam
detector.
6500MMK
The 6500MMK allows reflected beam detectors
and reflectors to be mounted to either a vertical
wall or the ceiling. The kit allows for additional
alignment range in cases where the detector and
reflector cannot be mounted within 10° of each
other. The kit includes the hardware necessary to
mount either a single transmitter/receiver unit or
a single reflector.
BEAMHKR
The BEAMHKR allows the reflector to operate
in environments prone to the formation of
condensation. Condensation forming on the
reflector may result in trouble or false alarm
conditions. BEAMHKR will lessen the likelihood
of condensation by maintaining the reflector at a
temperature that is slightly higher than
surrounding air. The kit requires a 24V power
supply.
RTS151KEY (Test Function)
The remote test accessory allows for the
beam detector
to be tested and reset
remotely from ground level.
The test accessory provides test and reset
functions and a red LED that mimics the
alarm LED on the detector.
