Transmission of alarm signals to alarm receiving centres
Where Automist has been installed for the protection of vulnerable people, it is essential that the activation
alarm (AP10) is also transmitted to an alarm receiving centre or a place where people are tasked with
responding on a 24/7 basis, so that management action can be initiated, and the fire and rescue service
mobilized. BS 5839-1:2017 or BS 5839-6:2019 provides more detailed guidance and recommendations.
In buildings housing vulnerable people, the pump flow alarm should be transmitted as a confirmed fire
signal to a permanently staffed location.
Controller
The controller is 155 mm (height) by 42 mm (depth) by 155 mm (width), less than 1 kg in weight and has an
IP rating of IP45. It should be positioned near or next to the consumer unit, or if not possible next to the
pump. It should be stored in an area that is a separate compartment from the protected volume and
accessible for the person responsible for maintenance or someone who may require access to the stop
button. In certain situations, it is beneficial for it to be accessible without requiring entry to individual flats.
The controller persistently produces a warbling sound and shows a red LED flashing when the Automist
system is in fault and requires attention.
Valves
A WRAS approved isolation valves is required so that the Automist Smartscan Hydra system can be shut off
from the water main. All such valves must be labelled with the included warranty void anti-tamper sticker.
This enables clear identification of any tampering with the water valve (note: spare stickers can be ordered
from Plumis).
The product is also supplied with a non-verifiable single check valve assembly (suitable for backflow
prevention up to Fluid Category 2), intended for installation at the inlet. Maximum working pressure: 10.0
Bar. Cold water use only.
The single check valve supplied with this product must be installed to maintain the validity of the WRAS
approval.
A full flow test is performed as part of the commissioning process (see page 77 for full details), after which
water is pumped out of the supply hose or pipe using a bicycle pump or an air compressor pump (max 8
bar).
Electrically operated devices
The electrical supply to the Automist pump should be installed in such a way as to minimize the risk of
electrical supply failure by having a separately fused connection taken after the meter and from the supply
side of the domestic or residential fuse box, using fire-resisting cable.
Strainer
The Automist strainer is made of corrosive-resistant material with the flow direction given on the body. It
should be installed in each water supply connection (see page 72 - D) Second Fix - Connecting the Water
Supply).
