IAM WORKING IN A FACILITY THAT REQUIRES A DOORBELL FOR THE HEARING IMPAIRED.THE DOORBELL IS REQUIRED TO HAVE A FLASH & A CHIME. DOES ANYONE HAVE ANY INFO ON A COMPANY THAT MANUFACTOR'S SOMETHING SIMIULAR TO THAT?
MY SUPPLER HAS NO CLUE.
If you have an alarm supply dealer near you they usually have items like this or at least they might know where you can get them. They also make items like bed shakers for fire alarm systems. I see you're in New Jersey, you can check with ADI or Alarm Distributors in Hackensack.
