Disconnections

To disconnect any Alarm Signalling Equipment (ASE), a building permit from a registered building surveyor is required. Your monitoring company will also require a written request to disconnect and a copy of the permit. This applies for both permanent and temporary disconnections.

Examples of temporary disconnections are:

  • renovations to entire building protected by ASE
  • non-occupancy of building – ensure the site and/or building is made secure

We suggest you advise your insurance company of any intended changes.

Modifications

Any changes to your Alarm Signalling Equipment (ASE) needs to be approved by a registered building surveyor.

This includes:

  • Changing the monitoring status of inputs, i.e. from automatic alarm to a local alarm or a system where the signal is intercepted by the monitoring company
  • Amalgamating separate inputs into one control panel or Fire Indicator Panel (FIP)
  • Time delay of the signal (special fire brigade consent is required)
  • Changing the positions and/or types of detectors

Please be aware that fire maintenance contractors do not have the authority to make these changes – they can only carry out the changes once approval has been given by a registered building surveyor.

We suggest you advise your insurance company of any intended changes.

Isolations

Isolations can be useful management tools, however they are easily misunderstood. Always use the minimum isolation method that will suit your purpose. Minimum isolation occurs when zones or circuits of your system are isolated for a minimum of time at a panel (often referred to as a Fire Indicator Panel – FIP).

Isolation of circuits or zones (preferred isolation method)

Individual circuits or zones of an FIP may be temporarily isolated.

Examples are:

  • To perform maintenance
  • To accommodate works such as building or cleaning that may trigger a false alarm

Isolation of Alarm Signalling Equipment (ASE) – only use when absolutely necessary

There are now two types of ASE isolation possible:

1. Site ASE isolation

Use of the isolation ‘key’ at the ASE. This isolates the entire ASE for a maximum of 10 or 12 hours, after which time the system will automatically de-isolate. You may also use your key to de-isolate at any time. A typical use would be to perform standard maintenance works or checks on the system.

2. Remote ASE isolation

Your monitoring company may agree to a written request to isolate your ASE for a maximum of 24 hours, given exceptional circumstances. You may also be able to isolate a specific input.

Managing an isolated area

Always use minimum isolation methods.

When isolating an alarm or individual inputs or zones or circuits, please consider these actions:

  • Advise all building occupants, especially chief fire warden and floor wardens, of isolation
  • Advise all building occupants they should ring 000 for emergencies
  • Provide 24 hours security or a responsible person from the building to monitor the fire alarm system and area of isolation
  • Install a notice at entrances
  • In the event of an emergency, nominate a representative to meet the fire services on arrival
  • Inform all building occupants when the fire alarm system is back on line
