Manual call points may be used where the alarm / panel family used supports these and where 
they are configured to activate the associated relay. 

 

Fire alarm panels can add Automist by connection to a relay output provided that this operates 
only when the relevant heat detector(s) activate. If desired, SLAVE MODE can be ordered at time of 
purchase. This sets Automist to operate only while its alarm input remains active. 

 

Plumis recommends the use of mains powered heat alarms with back-up batteries since they 
significantly increase the reliability of the detection system. 

 

Ten-year lithium battery alarms are an acceptable alternative when installing a mains-powered 
alarm and relay causes unacceptable disruption. Wired lithium battery alarms with an integral 
relay are available: correctly configured, these report low battery to the Automist pump and cause 

it to go into a “beeping” error state, greatly improving safety: please refer to Plumis’ recommended

 

alarms documentation on the Plumis Partner Site. 

 

Wireless ten-year lithium battery alarms are recommended only where a scheduled maintenance 
programme is in place. Alarms that use standard replaceable 9V PP3 batteries are not 
recommended. 

 

When using wireless detection, it is not recommended to use complex house coding schemes with 
overlapping zones, as installer errors can easily lead to incorrect operation and are hard to track 
down. 

 

Where the relay is not installed adjacent to the pump that it triggers, FP200 or a suitable fire alarm 
cable that resists fire for at least 30 minutes must be used for the cable run between the pump 
location and the relay. 

 

Placement of heat detectors / alarms should follow either BS5839-6:2013 section 11.2 (h) to (n) or 
BS5839-1:2013 section 22.3. Notably this implies a working range of no more than 5.3m for heat 
alarms and gives guidance on unusual ceiling types. 

 

Automist

’s

 use of heat alarms 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 heat alarms:

 

 

Directly over the cooker, stove or oven.  

 

In areas with high humidity, like bathrooms or shower rooms, or areas to close to dishwashers or 
washing machines. Install heat alarms at least 3m away from these areas if possible.  

 

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. 

 

Near fluorescent lights. Electrical noise & flickering may affect the operation of the heat alarm.  

 

Closer than 300mm to light fittings.  

 

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 unlike case 
that the alarm and its connections are waterproof.  

 

On surfaces subject to significant vibration. 

IMPORTANT: 

Ensure Automist is only connected to the main heat alarm(s) in the volume it protects. You 

can check these interconnections using the product’s ALARM TEST MODE (see page

 30). In this mode, the 

alarm lamp will light to indicate a functioning alarm input. Ensure that Automist has been successfully 
returned to the System OK state following this test, and that the water supply remains open, and that 
nozzles are unobstructed. 

Please refer to BS 5839 for further information on the installation of heat alarms.
