Public Address and Voice Alarm Installation

We can install, commission and maintain your PA / VA system complying, where necessary, to the following British standards:

BS 5839-8 Code of practice for the design, installation, commissioning and maintenance of voice alarm systems.
BS EN 60849 Sound systems for emergency purposes.
BS 7827 Code of practice for designing, maintaining and operating emergency sound systems at sports venues.

If your need falls outside the standards quoted please ask us about the specialised services we can offer.

Sound Transmission Index Testing

Using the latest technologies from NTI, we are able to quickly and efficiently measure the STI-PA of your system in many locations through out your premises to gain a real picture of the intelligibility of your system. This information is then compiled in one easy to read document which shows the average STI and CIS figures for your system.

Rack Builds

DMS can build your system rack, test and configure it either on site or at a location of your choice.

Audio Editing

DMS can record your voice evacuation or public address message using professional voice-over artists and then edit the messages together with sounds and alert noises to create high quality announcements for your public address or voice alarm system.

Documentation

DMS can produce your technical documentation including operation and maintenance manuals, surveys and full technical reports. As standard all maintenance visits are documented in the visit report stating all tests carried out, results and recommendations if the results are outside the parameters set in the relevant British standard or manufacturers guidance.
