Automatic test and monitoring facilities
The Automist pump is not wet pipe and does not need to be churned to maintain reliability. It is a positive
displacement pump and locked motor rotors is addressed under the EN60335 standard part 19 'Abnormal
Operation'. It is possible to fit a power loss alarm to the system, to alert the user if power is cut. Because
the alarm is installed to detect a loss of power, it must be installed on a separate spur of the same circuit as
the Automist system.
Automist is also continually monitored through an RS-485 bus connecting every key component and raising
a warning if one item is faulty or has been tampered with or removed. We also monitor that the thermopile
sensors are reading temperatures and all heads are ready to operate.
Many options for such an alarm are available and Plumis recommends the purchase of an inexpensive
alarm like the one in the following link:
•
LED Power Cut Failure Outage Alert Automatic Alarm Warning Siren Indicator (ASIN - B01GE3NDB4)
Electrical design and installation
Electrical installations should conform to BS 7671.
IMPORTANT!
The maximum allowable data cable length in the system is 80m (from the controller to the
pump to the furthest head). It includes the maximum allowable data cable from pump to the controller of
30m plus the maximum data cable length to the furthest head from the pump of 60m.
Additives
Additives should not be used with Automist Smartscan.
Trunking and Pump Enclosures
Fireproof trunking can be used to house the sprayheads and conceal the associated hose or pipe for easy
retrofit. When the hose runs downwards from the ceiling inside the trunking, two stainless steel 90-degree
elbows (part no: P0014_A) shall be used to avoid the risk to the long-term reliability of the hose due to the
smaller than manufacturer recommended bend radius. During the hose cutting and installation, the end of
the hose shall be relaxed inside the trunking at a level between 6-10 cm below the lower edge of the
window in the trunking.
