The Honeywell System Sensor BEAM1224 series optical beam smoke detector is engineered as a 4-wire conventional device, allowing broad integration into industrial and commercial fire protection architectures. Because the device operates via standard dry-contact relay connections and continuous DC auxiliary power, it can interface seamlessly with dedicated conventional initiating device circuits (IDC) as well as modern addressable fire alarm systems via certified monitor modules.
Fire Alarm Control Panel (FACP) & Loop Interface
The detector interfaces with standard 4-wire conventional fire alarm control panels (FACPs) capable of supplying filtered DC auxiliary power within its rated operating range. For intelligent or addressable fire alarm control panels, integration is accomplished by connecting the detector’s independent alarm and trouble relay outputs to compatible addressable zone monitor or input interface modules on the signaling line circuit (SLC). This enables point-specific reporting on the central panel while leveraging conventional beam detection hardware across vast open spaces.
For proper system power budget calculations, the operating voltage range is 10.2 to 32.0 VDC for the standard BEAM1224 transceiver unit (15 to 32 VDC for BEAM1224S models). Maximum average current consumption at 24 VDC must be accounted for across all operating states: 17 mA in normal standby, 38.5 mA in alarm, 8.5 mA during fault conditions, and 28 mA when active in optical alignment mode.
Remote Test and Reset Stations
To support regular code-mandated testing in facilities with elevated ceilings where physical access to the transceiver is restricted, the BEAM1224 is fully compatible with external System Sensor remote stations. These stations provide remote testing and reset triggering from ground level:
- RTS151 / RTS451: Remote test stations equipped with keyless test capability for localized verification.
- RTS151KEY / RTS451KEY: Key-activated remote test and reset stations providing secure, authorized-only testing access.
Compatible Accessories & Hardware Extensions
The BEAM1224 architecture supports an array of modular system accessories designed to extend operating optical distances, support complex structural mountings, and prevent environmental condensation:
| Accessory Model | Component Type | System Compatibility & Functional Scope |
|---|---|---|
| BEAMLRK | Long-Range Reflector Kit | Extends beam span from standard 16–230 ft (5–70 m) up to 328 ft (100 m) using a 15.7 in × 18.1 in (400 mm × 460 mm) assembly. |
| BEAMMMK | Multi-Mount Kit | Heavy-duty bracket enabling ceiling or wall installations where direct structural alignment requires expanded positioning flexibility. |
| BEAMSMK | Surface-Mount Kit | Enclosure bracket tailored for exposed conduit and surface raceway wiring applications. |
| BEAMHK | Transceiver Heater Kit | Internal thermal element mitigating optical condensation and frost formation on the transceiver window in unheated spaces. |
| BEAMHKR | Reflector Heater Kit | Surface heating element designed for the passive retroreflector to eliminate dew or frost accumulation on reflective prisms. |
Field Termination & Wiring Specifications
Field wiring integration is executed via plug-in removable screw terminal blocks located within the transceiver housing. The terminal assembly accepts solid or stranded field conductors ranging from 12 AWG to 22 AWG. The passive reflector requires no electrical wiring, terminations, or auxiliary power supplies, ensuring single-ended cabling runs back to the initiating loop and power supply.
