Go to the Simplex web site. Their catalogs will show you all their stuff.

We usually refer to these as horn strobes. They can come with an electromechanical bell, a horn, or a device that generates the signal one wishes. You will find that they come standard with the word FIRE on the surface, but ca n be obtained with other wording.

You aren’t one of those miscreants, are ya??? Well, possibly you need one for your scientific happenings. Here is one you can buy – http://cgi.ebay.com/SIMPLEX-MODEL-2903-ALARM-AND-STROBE-COMBO_W0QQitemZ140153931843QQcmdZViewItem It is a SIMPLEX MODEL 2903 ALARM AND STROBE COMBO and is rather inexpensive…just right for a hobbyist.

it is a commercial item which it takes expensive equipment to run. you will be able to buy this from an electrical contractor in your area.

what you are looking for is called a horn/strobe. Simplex is simply a brand of fire alarm, mostly use in commercial applications. They are used for whole building fire alarms and connect to what are called horn circuits, which set off the horns and or strobes when the alarm is triggered. ADA now requires strobes as well as horns to be used to accomodate the hearing impaired.They are also required now to be in sync with one a further to prevent siezures. And also there are alot of fire alarm companies who manufacture horn/strobes.

It should also be noted that they work off of reverse polarity circuits, meaning that in normal operation (no alarm) the voltage polarity flows one way, and due to diodes inside the device, when the polarity changes, the alarm sounds. Oh, and strobes take more energy(amps) than the horns.

It should further be noted that you probably won’t find simplex alarms on ebay. The best you can do is to find a fire alarm dealer in your area and hope that they are a licenced simplex dealer. Or break in a warehouse and rip one off the wall and try not to get caught! Just kidding, DON’T do that.

Hope that this is a DA** excellent enough resolution for ya. Oh and try looking for simplex’s website. Or silent knight, a similar company. Or FCI. Or Firelight. Or Napco. Or EST. Or Notifier. Or System Sensor. Or Kidde. Or any number of fire alarm companies. Silly DA** kids.
