Eaton Wheelock EL4XSTR-NW Strobe with Backbox

Product Description

The EATON WHEELOCK EL4XSTR-NW is a 4-inch strobe notification appliance supplied with an integrated backbox, designed for fire alarm and life safety systems. This unit ships without a letter designation on the lens, making it suitable for installations where custom or blank lens labeling is required by the authority having jurisdiction. It is categorized as a combination sound and strobe device and is sold as a single unit. Licensed electricians and fire alarm system technicians are the primary installers of this appliance in commercial and residential life safety applications.

The EL4XSTR-NW is used in fire alarm notification appliance circuits where visible strobe signaling is required. The backbox is included, simplifying rough-in and reducing the need for separate backbox procurement. The no-letter lens configuration is typically selected when local code or project specifications require a blank or custom-labeled appliance. This device is appropriate for wall-mount installations in corridors, offices, and common areas as part of an addressable or conventional fire alarm system.

Installation Notes

Installation must be performed by a licensed electrician or certified fire alarm technician in accordance with NFPA 72 and applicable local codes. De-energize the notification appliance circuit and confirm the fire alarm control panel is in a safe service state before connecting or disconnecting this device. Mount the backbox securely to the wall structure at the code-required height before wiring the strobe. Do not apply power to the circuit until all connections are verified and the backbox cover is properly secured.
