The HNWC Wheelock Fire Alarm Horn Ceiling Mount RED will be there for you when seconds count and you need the most effective means of notification during a fire emergency possible. The unit's audible notification can prove dire during times of crises, as its blaring horn will not go unnoticed and can only signal one thing-to Get Out.

The Wheelock Fire Alarm Horn features a sleek modern design that will please building owners with reduced total cost of ownership. Installers will benefit from its comprehensive feature list, including the most candela options in one appliance, low current draw, no tools needed for setting changes, voltage test points, 12/24 VDC operation, universal mounting base and multiple mounting options for both new and retrofit construction. This model features 3 sound settings (90, 95, 99 dB), while all switches to change settings can be set without the use of a tool and are located behind the appliance to prevent tampering.

The unit features a Universal Mounting Base (UMB) designed to simplify its installation and testing. The separate universal mounting base can be pre-wired to allow full testing of circuit wiring before the appliance is installed and the surface is finished.

The series comes equipped with:

  • A combination of 12 and 24 VDC in one appliance providing the capability to use a single appliance for different installation requirements.
  • A universal, common base for retrofit jobs, limited space environments, and preexisting wire configurations.
  • It comes complete with a Contact Cover for protection against dirt, dust, paint and damage to the contacts.
  • The Contact Cover also acts as a shunting device to allow pre-wire testing for common wiring issues.

In most cases, the installation or expansion of a commercial fire alarm system is determined by code requirements. There is federal, state, and local codes that come into play, specifying who must install fire alarm equipment, what type of equipment must be installed, where and how it must be installed. Failing to comply fully with any of these codes can result in denial of occupancy permits, fines, legal and financial liability.

Sorry we do not offer technical support for these products because of local codes that come into play specifying who must install fire alarm equipment and where and how it must be installed. To read more, visit the National Fire Alarm and Signaling Code website.
