The Simplex 4903-9426 is an audible and visible notification appliance. For applications requiring audible/visible (A/V) notification with horn tones, these Simplex 4903-9426 combines a high-intensity strobe with a low-current electronic horn in a compact package that is easy and quick to install. Also, each appliance can be control independently from each others using conventional reverse polarity NACs.
In fact, this 4-wire operation A/V appliances are available with three strobe intensity levels (15, 75, or 110 cd) and with red or off-white housings. Furthermore, mounting can be semi-flush or surface mount on a standard single or double gang, or 4” square (102 mm) electrical box. Optional accessories are available to increase mounting and application flexibility.
TrueAlert non-addressable A/V horns provide an audible notification output that is a loud and penetrating, harmonically rich sound capable of a continuous or coded output per the controlling NAC’s capabilities. TrueAlert non-addressable A/V strobes can be set for free-run operation or synchronized operation using an on-board selection switch.
