Cooper Wheelock AS-24MCW-FW. Horn Strobe.

Cooper Wheelock AS-24MCW-FW Horn Strobe

The Cooper Wheelock AS-24MCW-FW is a ceiling or wall sounding appliance that combines an audible horn with a xenon strobe, designed for life safety systems in commercial, institutional, and industrial buildings. It’s part of Wheelock’s AS Series of 2-wire horn-strobes, offering a balance of performance, field flexibility, and ease of installation.

Although often referenced, note that the typical documentation is for the AS-24MCW-FR (red “FIRE”) version; the “FW” suffix indicates the same unit in a white housing for aesthetic flexibility.

Key Features & Capabilities

• Multi-Candela (MCW) Strobe Options
  The strobe provides field-selectable candela levels of 15 / 30 / 75 / 110 cd for wall mounting, allowing designers to tailor visibility to corridor size or lighting conditions.

• Selectable Continuous / Temporal Horn
  The horn portion supports either a continuous tone or temporal (Code 3) tone, selectable in the field.

• Three Volume Settings (dBA Levels)
  The horn offers three output levels (high, medium, low) in both tone modes, to match ambient noise conditions.

• 2-Wire Design (Simple Wiring)
  Uses a single two-wire circuit for both the horn and strobe, simplifying wiring runs while maintaining full functionality.

• Universal Mounting Plate & Easy Installation
  The unit uses a universal mounting plate that fits standard 4″ square, double gang, or also European 100 mm backboxes. As well as convenience in wiring and mounting is emphasized.

• Synchronization Support
  When used with Wheelock’s DSM / SM modules or compatible fire panels, strobes (and in certain cases horns) can be synchronized across multiple devices to ensure coordinated flashing and avoid adverse interactions (important to satisfy ADA / NFPA requirements).

• Strobe Flash Rate
  The strobe flashes at 1 flash per second over its regulated voltage range.

• Listings & Approvals
  Complies with UL 1971 (strobe) and UL 464 (audible) standards, also with additional approvals from MEA (NYC), CSFM, FM, and BFP (Chicago).
