The Honeywell System Sensor BEAM1224 conventional reflected optical beam smoke detector is engineered specifically for open-area protection in large facilities where point-type (spot) smoke detectors are physically impractical, cost-prohibitive to cable, or hazardous to maintain. Because the optical transmitter and receiver are combined in a single enclosure paired with an unpowered passive retroreflector, all 4-wire power and signaling conduits are isolated to one wall.
High-Bay Warehouses and Logistics Distribution Centers
In high-ceiling warehouse environments with open racking, vertical clearance often exceeds 20 to 40 feet, rendering spot detectors inaccessible without scissor lifts or specialized boom equipment. The BEAM1224 provides an operational throw ranging from 16 to 230 feet (5 to 70 meters) using the included 7.9-inch by 9.1-inch retroreflector, and extends up to 328 feet (100 meters) when paired with the BEAMLRK long-range reflector kit.
- Simplified Field Cabling: Requires 10.2 to 32.0 VDC wiring only at the transceiver unit; no wiring, conduit, or power is required across the facility at the reflector target.
- Ceiling Coverage Compliance: Accommodates standard smooth-ceiling spacing between 30 and 60 feet between adjacent optical paths, with maximum sidewall spacing set at half the beam spacing.
- Elevation Testing Access: Compatible with RTS151, RTS151KEY, RTS451, and RTS451KEY remote test stations, enabling ground-level annual NFPA 72 testing without requiring access equipment.
Aircraft Hangars and Heavy Manufacturing Plants
Industrial production halls and aircraft maintenance hangars feature wide clear spans, significant thermal air movements, and airborne contaminants that cause premature failures in conventional spot detectors. The BEAM1224 incorporates internal Automatic Gain Control (AGC) that continuously monitors baseline optical signal strength and compensates for slow dust and particulate accumulation over time.
For facilities where equipment, hoists, or overhead cranes momentarily cross the optical path, the detector prevents false alarms: an abrupt blockage causing 96% or greater obscuration automatically reports as a trouble/fault state rather than a fire alarm. System engineers can match site conditions using six selectable sensitivity settings:
- Fixed Obscuration Modes: 25% (Level 1), 30% (Level 2), 40% (Level 3), and 50% (Level 4).
- Acclimate Adaptive Modes: Acclimate 1 (30% to 50%) and Acclimate 2 (40% to 50%) automatically adjust sensitivity thresholds to ambient changes.
Commercial Atriums, Convention Centers, and Auditoriums
Public-facing atriums, arenas, and convention halls demand life-safety hardware that does not compromise interior aesthetics. The BEAM1224 features an integrated paintable trim cover that allows the transceiver housing to match interior design finishes. In addition, its independent optical alignment mechanism provides +/- 10 degrees horizontal and vertical adjustment without moving the base housing, guided by an internal gunsight and a 2-digit signal strength display for rapid commissioning.
Cold Storage, Unconditioned Structures, and High-Condensation Facilities
With a wide operating temperature envelope spanning -30°C to 55°C (-22°F to 131°F) and relative humidity tolerance from 10% to 93% non-condensing, the unit functions reliably in unheated industrial warehouses and cold-chain facilities. In applications where temperature swings cause optical dew or frost formation, optional BEAMHK and BEAMHKR internal heater kits can be installed in both the transceiver and reflector assemblies to ensure clear optical transmission.
