How to Draw Fire Alarm Plans

BS5839-1:2013 states that zone plans are required on every system of whatsoever size, and should also be noted every bit a major non-compliance during routine maintenance, when they are not displayed on existing installations.

This gives you lot (the installer or maintenance provider) the responsibleness to so give details to your customer of how they can obtain zone plans for each CIE position on their organization, to ensure compliance.

Whether y'all complete your own cartoon 'in-house', or outsource to a burn systems CAD specialist this guide will take you through the mutual questions we've been asked over the years when producing zone plans.

What must be on the zone plan?

The zone plan must be a geographical representation of the edifice clearly showing the division into fire alarm zones.

The drawing of the edifice layout should clearly evidence terminal exits, mutual escape routes, circulation areas and stairs. A 'block' diagram which doesn't testify this information is not adequate.

Fire alarm zones must be clearly identifiable; we notice that unproblematic block colour is the clearest way to achieve this. Diagonal hatching or a thick coloured outline of the zone could also exist used, but ensure that the important features of the building as mentioned above are yet clearly visible. Individually labelled zones are usually the best option; however using a legend of colours can also be effective. If you opt for a fable, make sure y'all can use a good range of colours. Systems which go to a higher place 7 or 8 zones usually hateful some similar colours have to be used, which can cause confusion on these types of zone plan.

You must indicate a 'You lot Are Here' indicate on your zone plan, so the user can locate where they are in relation to the zone in alarm. It's also best practice to have the right orientation of the building based on where the 'You Are Here' points to. For case, if when y'all are stood facing the CIE and zone programme there is a fire get out door to your immediate right, this door should as well announced on the correct on the zone plan. These are simple steps you lot tin take to convalesce any potential confusion for anyone unfamiliar with the building in the event of an alarm.

For big sites where all staff and visitors are inducted, using their standard site programme in it' familiar orientation may be the best selection. The 'Yous Are Here' is nevertheless required but rotating their site plan they utilise or for induction or on Health & Prophylactic boards, for example, may really be more than confusing.

Can I put my logo and contact details on the zone programme?

Yep, there are no restrictions on branding the zone plans y'all provide. Brand certain this is kept to a minimum and at the edge, leaving the main area clear.

What other data is allowed to be on the zone programme?

Once more, at that place are no articulate restrictions on what you tin add, but be careful non to detract from the purpose of the zone plan – to clearly locate the zone in alarm.

For monitored systems, adding the monitoring station phone number is a good idea. Not only is information technology then readily available to the user for weekly testing, it likewise acts as a reminder that they need to brand that call earlier testing the system. Anything that could help the user deport out weekly tests effectively should be considered. For case, showing the callpoints and their numbers (numbers every bit they are listed in their log book, not address numbers) is helpful, every bit is brief instructions on operating their control console. Yet, remember to continue the zone plan large plenty to exist clear. Adding instructions to the plan usually means a minimum paper size of A3 would exist required.

The addition of all fire warning devices can exist acceptable on pocket-sized systems, but you should do caution with this. Zone plans that include devices, accost numbers, wiring and even dB levels volition exist too confusing. Whilst a 'universal' drawing similar this on display can be useful to a burn down engineer attending for a maintenance visit or fault call, most of the information would be meaningless to the end user. Having this information on drawings as role of the arrangement's Performance & Maintenance transmission, stored by the CIE in a clearly marked folder is much amend practice.

Where should the zone plan(s) be mounted?

The zone plans should be mounted by each CIE signal, which are all the fire alert control panels and repeater panels. Basically, anywhere that indicates the zone in warning should accept a zone plan installed, with an accurate 'Yous Are Here' marked on.

Some zones are non in this building, should I bear witness them on this zone program?

Yes. If the zone LED will light on the panel, this should be marked on the zone plan. For example, if zones one to 4 are shown coloured only Zone 5 is the remote gatehouse, you should ideally show the whole site on i plan keeping the zones and building layout clear. Where this is not reasonably possible, adding a note to the program stating 'Zone 5 – Gatehouse' will suffice.
