The Wheelock HS horn and horn strobe appliances are ideal choices for retrofit applications as well as new installations. The HS/HS4 satisfy virtually all requirements for indoor, wall and ceiling mount applications.

The HS horns include a selectable continuous horn tone or temporal pattern (Code 3) with three selectable dBA settings for each tone. Strobe options include the Wheelock patented MCW Multi-Candela strobe with field selectable candela settings of 15/30/75/110cd or 135/185cd for wall mount and 15/30/75/95cd or 115/177cd for ceiling mount.

The HS4 horn and strobe inputs are electrically isolated to allow for independent operation of the strobe circuit and the horn circuit. The horn and strobe may also be wired in parallel to operate on a single circuit.

These versatile horn and horn strobe appliances may be synchronized using Wheelock DSM Sync Modules, Wheelock Power Supplies or other manufacturers panels incorporating the Wheelock Patented Sync Protocol.

All models are designed for maximum performance, reliability and cost-effectiveness while meeting or exceeding the latest requirements of NFPA 72/ANSI 117.1/UFC and UL Standards 1971 and 464 as well as meeting ADA requirements concerning photosensitive epilepsy.
