f)
Where necessary, supports for hoses or pipework should be suitably lined to prevent corrosion
and abrasion.
h)
The maximum support spacing should be in accordance with the manufacturer’s installation
instructions.
Detection Devices
Wired or wireless detectors in combination with scanning infrared sensors on the nozzles electronically
trigger Automist, acting as an initiation device equivalent to a glass bulb bursting under the influence of
heat. If the initiation device (detectors paired to Automist) are removed or faulty, it will cause the system to
enter fault mode: persistently warbling sound and red LED flashing (see page 75). This condition can be
hushed for 12 hours by pressing the STOP button but can only be permanently removed by addressing the
fault. In this way, unlike with a sprinkler, the points of detection are monitored.
IMPORTANT!
As a default, the early warning alarm required for the building is in addition to the detection
used to trigger Automist, although they can be integrated (see page 50). The use with other types of
detection not sanctioned by Plumis could lead to death or injury. The system is designed to be triggered by
compatible detectors/alarms only (see page 48).
•
Placement of detectors must follow either BS 5839-1:2017 and/or BS 5839-6:2019. Notably this
implies a working range of no more than 5.3m for smoke detectors and gives guidance on unusual
ceiling types.
•
Automist Smartscan Hydra’s use of alarm(s) or detector(s) does not affect or reduce any
requirements for the use of smoke detection in the property. Smoke detection provides a critical
independent early warning, especially with slow-growing fires.
DO NOT
install detector (or alarm):
•
Directly over a sink, cooker, stove, fireplace, or oven
•
Do not locate a detector within 1.5m of any cooking appliance (as per the manufacturer’s
recommendation)
•
Next to a door or window that would be affected by drafts i.e. extractor fan or air vent
•
Outside
•
In or below a cupboard
•
Where air flow would be obstructed by curtains or furniture
•
Where dirt or dust could collect or block the sensor
•
Where it could be knocked, damaged, or inadvertently removed
•
Adjacent to, or directly above, heaters, air-conditioning vents, or ceiling fans
•
In an area where the temperature may fall below 4°C or rise above 37°C
•
In such a position that it is difficult or dangerous to reach for testing or maintenance or where
children can easily tamper with the alarm
•
In an area where water or other liquids may enter the alarm, except in the extremely unlikely case
that the alarm and its connections are waterproof (e.g. bathrooms)
•
On surfaces subject to significant vibration
Ensure Automist Smartscan Hydra is only paired to the desired detector(s) in the volume it protects. You
can check these associations using the product’s ALARM TEST MODE (see page 86). In this mode, alarms
may be triggered which will cause their linked heads to perform two scans and then return to an idle state.
Ensure that Automist Smartscan Hydra has been successfully returned to the System OK state following this
test.
