Eastfield Technical Services

Eastfield Technical Services can design, install, supply, commission, repair and maintain voice alarm with full back up from the manufacturers of the voice alarm equipment. Voice alarms have one central control panel (rack) from which fire microphone stations can be positioned in different parts of the building

Past Projects An example of where we installed a Baldwin Boxal Voice evacuation rack system, which included Public Address, voice alarm and background music system. This was installed in the late 1990s and has only be recently replaced.

Pre-recorded messages in electronic modules in the main rack can be activated in a fire or emergency situation from the buildings fire alarm system or in the reception office via emergency button or panic alarm. These electronic message modules have total priority over the system being used in any other manner ie: public announcements or background music.

The cabling of a voice alarm system from the rack to the speakers around the building will be wired in fire-proof cable. Each room or area will have two speakers wired on A and B circuits fed from the main rack on separate cabling systems with separate amplifiers. This is to cover electronic failure of an amplifier in a zone, or cable damage, or speaker failure; still enabling coverage of all areas. All speakers will have fire-domes fitted as to the BS standard BS5839-9.

All circuits, including fire microphone stations, electronic amplifiers, A and B speaker circuits per zone are all fully monitored and any breakdown in the circuits will result in audio-tone and visual warning on the rack of problem needing rectification.

All panels will carry full battery back-up to allow the systems to remain active, without mains power, for eight hours and then go into an alarm situation which will subsequently allow it to be re-set back into standby.
