Improving the system’s robustness (the ability of the system to tolerate disruption) is required when the
water, power supply or obstruction mitigation has poor reliability and/or the consequences have high
impact.
The measures listed are used, as default, in isolation or combination to increase the levels of robustness
and/or resilience:
a)
System
1)
Fault signals indicate an error: persistently warbling sound and red LED flashing (see page
75)
2)
Visual inspections of the Automist controller at a rate, equal to, or greater than, the
frequency of any alarm testing already in place (e.g. at least weekly in residential care). If
there is no alarm testing in place a ‘reasonably practicable’ inspection rate should be
chosen (see page 94).
3)
Remote fault monitoring using the Automist IoT controller which generate alerts of
outages.
b)
Detection
1)
Battery powered alarms permitted as monitored by system fault signals (see page 75)
2)
Controller visual checks in line with alarm testing frequency (see page 94)
3)
Battery powered alarms not permitted; mains powered alarms with battery backup only
4)
Detection integrated into existing BS 5839-6:2019 + A1:2020 system, Grade C or above
(see page 50)
c)
Sufficient water supply should be ascertained at a time of peak demand, so that there is sufficient
pressure and flow available from the mains to allow the system to perform. As the water supply for
Automist is shared with the domestic or residential supply, the water must be capable of providing
the minimum flow and pressure. If either is not sufficient it must be boosted to provide the
minimum requirement by a mains boost and tank (see page 36), of at least:
1)
80 litres
2)
200 litres
3)
500 litres
d)
The electrical supply to the pumps should be installed 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 consumer unit (see BS 7671), using approved fire-resistant cabling. Back-up power supply and
automatic changeover functionality can be provided by:
1)
An emergency generator
2)
Uninterruptible power supply (UPS)

3)
Dual supply from both the communal (landlord's supply) and dwelling supply (residential
or high rise only)
4)
Remote monitoring (IoT) using the Automist IoT controller which generates alerts of
outages in combination with a suitable service contract
e)
Sprayhead placement
1)
Preferred positions are locations where the likelihood of a sprayhead being obstructed is
reduced (see page 30).
