The actual routes of cables must be added. If the note ‘All cable 2c 1.5mm fire rated (red)’ is added, then just any cable that doesn’t fall into this description can be individually identified on the drawing, i.e 4 core cable. Add a general note to all your drawings detailing the cable type and size. The cable type and size can be taken care of fairly easily. the type, sizes and actual routes of cables. Also add the routes of any aspirating pipework installed, and include the position of the sampling points and any low level test points that may be present.Ĥ. (e.g Manual Call Point c/w integral short circuit isolator). Where short circuit isolators are integral to some or all of the devices, it may be clearer to add this to the description in the key. These are all other items pertaining to the fire alarm system installed. the positions of all equipment that might require routine attention or replacement (e.g short circuit isolators and remote indicators) EOL Z1 for the end of the Zone 1 circuit or EOL SCCT2 for the end of sounder circuit 2.ģ. It’s useful to also state the circuit that the EOL relates to, e.g. This is usually just noted as ‘EOL’ next to the relevant devices. (e.g Access Control, Lift, Door Holders) Add all address numbers (including loop designation) for addressable systems, and all positions of end of line resistors.
When marking the positions of interfacing equipment, detail what these are individually interfacing with the fire alarm. The main thing to remember here is to include a key or legend, detailing what each of the symbols are. Use a different symbol for each type of device, these can be very simple if you’re not working on CAD. Mark the positions of all the fire alarm system devices. the positions of all manual call points, fire detectors and fire alarm devices
Also include the battery cabinets, if these are installed and remote to the panels, sometimes these are situated in cupboards or store rooms nearby.Ģ. The positions of all the fire alarm control panels, repeater panels and all associated power supplies. the positions of all control, indicating and power supply equipment Once you have your building drawings, here’s what to include:ġ. Remember, you’ll need these for the zone plan too so these should include all exits, circulation areas and stairs as a minimum. However, these are not always available, hand drawn sketches will also suffice as long as they are an accurate representation of the building. In situations where you can obtain full CAD quality plans, this is a great start. Let us guide you through what these drawings should include.įirstly you’ll need adequate drawings of the building(s). BS5839-1:2013 Clause 40.2 (c) – AS-FITTED DRAWINGSĪs part of the documentation process, when installing or modifying a fire alarm system, as-fitted drawings must be provided for the works undertaken.
