Electronic Alarms and Home Security Devices - I feel dumb asking this, but I'm no electrician...

I'm looking for a very simple solution to a delema I have been experiencing. I am almost deaf and when a customer comes into the office I need to know, thus I need a simple type of indicating system.

I'm thinking of a magnetinc type door sensor that somehow momentarily flashes or illuminates a light to indicate a customer is waiting for service.

Im sure the solution is simple but I'm not a security specialist so I have come to you for a solution.


Any assistance will be very much appreciated!

Check with Radio Shack. I'm pretty sure that they sell a gadget that hooks into a normal doorbell circuit with a flashing light for the signal. You simply replace the normal doorbell switch with a door switch that will handle the current.

Thanks Ron, I will check with them...
I'll let you know.
