Simplex 4903-9418 Wall Horn Strobe Red P/n:0626587

Simplex 4903-9418 horn strobe is a non-addressable audible and visible notification. For applications requiring audible/visible notification with horn tones, these Simplex 4903-9418 series appliances combine a high-intensity strobe with a low current electronic horn in a compact package that is easy and quick to install. The horn provides a loud and penetrating, harmonically rich sound suitable for either coded or steady operation as determined by the selected SmartSync mode.

With both audible and visible controls carried on the same two-wire NAC circuit, using the SmartSync operation (patent pending) can provide the opportunity for significantly reduced installation time and expense for both retrofit and new construction.  These A/V notification appliances are available with three strobe intensity levels and with red or white housings. Also, mounting can be semi-flush or surface mounted on a standard single gang, double gang, or 4” square (102 mm) electrical box. Optional accessories are available to increase mounting and application flexibility.

Typically, fire alarm control panels activate both audible and visible notification upon receipt of an alarm. At the direction of an authorized operator (or by pre-determined program), audible notification appliances may be silenced before the alarm condition is reset (on-until-silenced) while the visible notification appliances are kept activated until the alarm condition is reset (on-until-reset). This operation has traditionally required two different circuits (four-wire operation). The Simplex SmartSync operation mode provides this function using a single circuit (two-wire operation).
