I'm currently designing a basic stock control system in access 2007 and have created an expression to calculate the price per unit by dividing price by number of units. But when I check the table the data has not been saved, but shows up on the form. Any help would be great as i'm new to this. Thanks

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 another 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 OKorder. 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** good enough answer 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.
