The EATON Wheelock Eluxa EL3RMT is an outdoor multi-tone horn for indoor/outdoor wall or ceiling mounting, rated NEMA 3R and IP54. UL certified for fire protection and UL 464, with FM and CSFM.
In short
- Type: Multi-Tone Horn; order codes EL3RMT-NR · EL3RMT-NW.
- Operating voltage 16 – 33 VDC/FWR (horn only also 8 – 17.5 VDC).
- Multiple tones: horn, bell, March Time, Code 3, slow whoop, siren and more, up to 88 dBA at 10 ft.
- Operating temperature -40°C to 66°C, 95% RH.
- Mounting plate or surface box with pre-wire, pre-test capability.
How the appliance works
It connects to a 2-wire notification circuit. Tone and volume are selected on the device per the project design.
Removing the appliance gives a supervision fault at the panel; all appliances are backward compatible.

The critical point: the mounting accessory sets the rating
The NEMA 3R / IP54 or NEMA 4X / IP66 rating is met only with the included mounting accessory (plate or box). Devices per circuit are calculated from the current tables for each tone and candela.
General notes on notification devices
- Audibility: in public mode the alarm must be at least 15 dBA above the average ambient sound level, per NFPA 72.
- Synchronisation: where more than two strobes are in one field of view they must flash in sync, to reduce visual disturbance.
- Strobe candela and spacing are chosen from room size and the NFPA 72 tables; strobes are required in public areas, public toilets and other spaces per the code.
- Voltage drop is calculated on every notification circuit so the last device stays within its operating range, within the circuit’s current limit at the panel.
General engineering notes
These points are general principles from NFPA 72 and common design practice, not from the EATON datasheet. The final decision rests with the project’s approved designer per the adopted edition of the standard and the authority having jurisdiction.
Installation steps
- Fix the mounting plate or box to the wall or ceiling.
- Wire to the plate or box terminals (pre-wire, pre-test).
- Set the tone on the device switches.
- Hang the appliance on the hinge, secure it, and test from the panel.
Common mistakes
- Outdoor installation without the included mounting accessory.
- Not calculating current for the selected tone and candela.
- Mixing unsynchronised strobes in the same field of view.
Inspection and maintenance
Before any test or maintenance, notify the owner, the monitoring station and everyone affected, as testing may operate alarms or linked outputs. The owner is responsible for inspection, testing and maintenance per NFPA 72 and the authority having jurisdiction, preferably by a qualified company.

FAQ
3R vs 4X?
4X is the higher rating (IP66) and resists corrosion and ice; 3R is IP54.
Is the amber strobe for fire alarm?
The amber lens is certified for emergency warning per UL 1971.
