Fire Alarm Types

Below is a basic description of fire alarm systems, so you know what you have or what you may be getting yourself into. Please feel free to call us to discuss what you might need and we can advise the best options.

If you have an existing Fire Alarm installed you need to know what type it is. Call us to discuss.

Most alarms require monthly testing by IPQs (Independent Qualified Person), although some only need three monthly testing. Contact us for advice on your system.
