Voice Alarm Systems

Weekly

  • Operate a manual call point to test all voice alarms to ensure the correct message is sounded and test any emergency microphones for correct operation. 

Quarterly

  • Voice alarm batteries should be checked to ensure they are in date and if vented batteries are used as a standby power supply the batteries, electrolyte level and connections should be visually inspected. 

Six Monthly

  • Check logbook to ensure all previous faults have been rectified.
  • Inspect entire system to ensure that any building structure changes that have taken place do not impair the system in any way and to check if additional devices are required.
  • Check all batteries (except those in radio controlled devices) to ensure they are in date, in good condition and electrolyte levels and specific gravity are correct. Then carry out a load test to ensure they are not likely to fail before the next service visit.
  • All fault indications and circuits should be tested by simulating faults where possible.
  • All printers should be checked for operation and to ensure that all text is legible.

Annually

  • All areas should be tested to ensure the correct messages are received in each area, that the messages are intelligible and audible and the sound levels compared to previous tests.
  • All loudspeakers should be inspected for damage.
  • Any phased evacuation programme should be checked.
  • Any manually operated messages should be tested.
  • Cables and fixings should be checked for damage.
  • All remote indicators should be checked
  • All permanently illuminated unmonitored filament lamps should be changed.
  • Radio signal strengths should be checked to ensure they are adequate.
