Mircom BEAM1224 SERIES Conventional Beam Smoke Detectors
Description
System Sensor’s BEAM1224 is uniquely suited for protecting open areas with
high ceilings — areas where other methods of smoke detection are diffi cult to
install and maintain.
The BEAM1224 is a four-wire conventional refl ected beam smoke detector, which
is uniquely suited for protecting open areas with high ceilings, where other
methods of smoke detection are diffi cult to install and maintain. It is to be
used with UL Listed compatible control panels only. An advantage of this
single-ended refl ective design is that it is much easier to install than the
dual-ended projected beam detectors. Alignment is quickly accomplished via an
optical sight and a two-digit signal strength meter incorporated into the
product. Another advantage of the BEAM1224 is that it is listed for operation
in temperatures ranging from –22°F to 131°F. This means it can be used in open
areas to provide early warning in environments where temperature extremes may
exceed the capability of other types of smoke detectors.
BEAM1224 consists of a transmitter/receiver unit and a refl ector. When smoke
enters the area between the unit and the refl ector, the smoke causes a
reduction in the signal. When the smoke level reaches the predetermined
threshold, an alarm is activated.
Features
- 16 to 328 foot protection range
- Single-ended, reflective design
- User friendly alignment procedure
- 6 user selectable sensitivity levels
- Optional integral NFPA 72 sensitivity test feature
- Removable plug-in terminal blocks
- Digital display for easy alignment
- Built-in automatic gain control compensates for signal deterioration from dust build-up
- Remote test station optional
- Paintable cover
- Easiest alignment in the industry
- Heater kits for transmitter/receiver and reflector option
BEAM1224 has four standard sensitivity selections, along with two Acclimate™
settings (adjustable sensitivity). When one of the two Acclimate settings is
selected, the detector will automatically adjust its sensitivity using
advanced software algorithms to choose the optimum sensitivity for the specifi
c environment.
BEAM1224S is also equipped with an integral sensitivity test feature, which
consists of a test fi lter attached to a servo motor inside the detector
optics. When the remote test station RTS451 is used, the motor is activated
and moves the fi lter into the pathway of the light beam, to test the
detector’s sensitivity. This integral sensitivity test feature allows the user
to quickly and easily meet the annual maintenance and test requirements of
NFPA 72.
