1 SYSTEM MANUAL Description PUCK is a revolutionary fire suppression system offering discrete protection coupled with industry leading pricing, efficient system design and easy install. PUCK s lightweight nozzles sit just 3mm below the ceiling making them non-intrusive whilst offering complete protection. These nozzles connect to a compact pump unit using flexible pipework and easyfit fittings. This keeps design and install time to an absolute minimum and allows for potentially large install savings. The PUCK pump unit includes a self-test facility which is adjustable in the companion app. The app monitors the unit in real time whilst receiving alerts on faults and activations. PUCK is compatible with all fire panels offering fire and fault n/o and n/c contacts. Rev by Puck Fire Ltd

9 SYSTEM DESIGN This manual contains manufacturers recommendations for the design, installation and commissioning of the PUCK fire and suppression system. This manual should be read in conjunction with the following standards as applicable: BS 8458 BS 9251 BS 9252 BS 7671 (Other standards may apply) Category of System The designer should at an early stage determine which category of system is applicable, as this affects various design considerations, such as the water requirements for the system. The category of system should be determined by the type of building as shown below. Domestic occupancy Single family dwellings such as: Individual dwelling house Individual flat Individual maisonette Transportable home Houses of multiple occupation (HMOs) A) Bed and breakfast accommodation A) Boarding houses A) Blocks of flats 18 m or less in height and with a maximum total floor area of m2 B), C) Residential occupancy Blocks of flats greater than 18 m in height C) Sheltered and extra care housing Residential care premises Residential rehabilitation accommodation Dormitories (e.g. attached to educational establishments) Hostels A) Buildings with more than two floors and five or more lettable bedrooms should be treated as a residential occupancy. B) Where the fire strategy requires the communal rooms and corridors to be protected by a watermist system, then the building should be treated as a residential occupancy.

10 C) This height is the height of the floor of the top storey above ground. Water Supplies Our recommendation is to install 1 pump for domestic occupancies and a dual pump system for residential occupancies. Where the mains water supply connection serves only the watermist system, the flow rates at each pump must be 12lpm. Where the mains water supply connection serves both the watermist system and the domestic or residential occupancy supply, the watermist system should be capable of providing the water demand at the pump/s by: a) the operation of an automatic priority demand valve; or b) for domestic occupancies, the flow rate at the pump plus at least 25 L/min; or NOTE 1 Attention is drawn to the water regulations, which might require a greater minimum flow rate. c) for residential occupancies, the flow rate at the pump plus at least 50 L/min. NOTE 2 Attention is drawn to the water regulations which might require a greater minimum flow rate depending on the design demand for the occupancy Flows should be tested and verified at the main water supply pipe to the property

11 Nozzle Spacing, Flat Ceilings 4x4m Grid (16M2) Max 2m from wall Minimum distance between nozzles =2m Nozzle Spacing, Sloped Ceilings- Where nozzles are fitted within a sloping ceilings, nozzle positions should be determined by the pitch of the ceiling. Where the pitch is below 30, nozzles should be mounted at standard spacing s when measured in line with the pitch of the ceiling. Where the pitch is 30 and above, the first row of nozzles should be mounted within 300 mm radially from the apex of the ceiling. All nozzles should be mounted perpendicular to the ceiling as shown below

12 Distance from Obstructions Nozzles should be positioned away from obstructions to allow a 140 degree spray pattern. Nozzle orientation

13 The preferred nozzle outlet orientation is perpendicular to the walls Maximum Pipe Lengths Pipe work should be configured as a loop not exceeding 60m in total length. Maximum 40 nozzles per loop. Loop length must be reduced by 1m for every tee or elbow added on the loop. Pipe length from the tee to the nozzle can be up to 1m long with one elbow without reducing the loop length.

14 Multi Loop Configuration example Pipework Flexible tubing should only be used behind a fire rated barrier Stainless steel tubing should be used for any areas where pipework is exposed. Nozzles for exposed pipework should not be positioned more than 300mm below the slab

16 INSTALLATION & COMMISSIONING WARNING Mains voltage electricity and high pressure water are present within this product. Care should be taken when installing the product. Installation should only be carried out by trained engineers. Appropriate PPE should be worn at all times when installing the product. Eye protection, gloves, safety boots and hard hat. 1. Remove all packaging from the components provided. 2. Install a 240v, 13A un-switched spur next to the proposed pump position.

17 3. Connect strainer, inlet manifold and flexible hose to the mains water (ensure mains water is switched off before breaking into the water supply). 4. Verify the water supply flow by running it into a bucket to confirm the correct flow 5. Ensure the isolation valve in the inlet manifold is set to the closed position. 6. If provided with a monitoring system make connections to fire and fault relays as required. Access can be gained to the electronics by removing the screws on the lid on the underside of the pump.

18 WARNING The pump unit must be completely powered down before opening the electronics enclosure Fire & fault connections 7. Refit lid to the electronics and position the pump it it s final location. The pump must be situated in a well ventilated area with no less that 100mm of free space around all sides of the unit. The top of the pump unit must stay clear of any objects to allow for proper airflow and performance. The pump must be located in a position above 4 C. 8. Connect power cable to un-switched spur ensuring that the power remains switched off at all times. Do not run the pump without water running through it. This will damage the pumps. 9. Use the threaded end of the inlet Manifold to connect directly to the threaded fitting on the bottom section of the pump. Warning! This fitting should only need to be hand tight if this does not create a seal tighten very slightly with a spanner until a seal is created. Overtightening will damage the components.

19 10. Install pressure relief arrangement to the top of the pump ensuring it is correctly orientated and connect the drain from the pressure relief manifold to the waste pipe. Do not adjust the pre-set pressure relief valve TO SYSTEM PIPEWORK AND NOZZLES CONNECT TO DRAIN 11. Install pipework to the system using flexible pipework push fit fittings and supporting P-clips. All flexible pipework should be installed behind a fire rated barrier such as plaster board, any

20 exposed pipe should be installed in steel pipework. Pipework must never be exposed to temperatures below 4 C. 12. Cut the pipework to length using pipe cutters ensuring a square edge is achieved with the cut. CORRECT INCORRECT X 13. Easyfit fittings Insert pipe into fitting until it will not go any further. Tighten nut by using two spanners. One spanner to tighten the nut and one spanner to hold the body of the fitting Example of ferrules correctly seated on pipe work

21 14. Pushfit - Apply silicone lubricant to the end of the pipework. Insert the pipe into the fitting pushing hard to ensure that the pipe is inserted by 25mmmm. Ensure pipe is straight and is not being pulled to one side as this may create leaks CORRECT INCORRECT X WARINING Pipework and fittings must not be installed in temperatures lower than 5 C as this can affect the ability of the pushfit to grip onto the pipework and create the required seal. 15. Use a 57-64mm hole saw to create the holes in the ceiling for fitting the nozzles. 16. Install nozzles ensuring that the 1/4 adaptor with a bonded seal is tightened with a spanner. Ensure bonded seal is used. Thread lock may be used if required. DO NOT USE PTFE OR ANY OTHER TYPE OF THREAD TAPE 17. Ensuring that the pipe network is complete open isolation valve on the inlet manifold to allow mains pressure water into the system.

22 18. Slowly loosen the nozzle furthest away from the pump set to bleed the pipework of any trapped air. Allow any excess water to drain into a bucket. When all of the air has escaped remake the seal. Most remote nozzle Max pipe length before tee 800mm 19. After ensuring that there are no initial leaks power up the pump to charge the system. 20. Leave to stand at system pressure for 1 hour. The pipe work will stretch over time causing some initial loss in pressure however it will settle to around 45bar. The pumps may operate for up to 1 second to a day to make up for any small losses in pressure in the system. The pipe network should not be subject to significant leaks. The pumps should not operate more than once a day to make up loss of pressure or it may risk affect the life span of the components. Any leaks should be repaired immediately to avoid risk of damage to equipment. 21. When satisfied that there are no leaks power the pump down, shut off the water supply and put the nozzles into position using the retention springs. 22. Switch water supply and power back on to re-enable the system
