Mains Supply & Batteries
The Fire Alarm Panel 230V AC supply requires fixed wiring between 0.75 mm
2
and 2.5 mm
2
, a 3 amp fused
un-switched spur with local isolation, to be terminated into the fused terminals provided in the power supply
back box. The mains supply should be dedicated to the Fire Alarm Panel and should be clearly labelled
‘FIRE ALARM: DO NOT SWITCH OFF’ at all isolation points.
The standby will vary depending on the system loading. The PSU requires 2 x 12V 17Ah sealed lead acid
batteries. These are to be sited in the power supply back box in the provided enclosure along the bottom
edge. The batteries should be connected in series using the connection leads supplied. We recommend
the use of type Yuasa NP17-12I (FR) or other equivalent approved type.
Do not use larger or smaller capacity batteries on this system, larger batteries will not fully charge in the
time allowed and smaller ones will be overcharged and the service life will be reduced.
Using different capacity or type of batteries could also invalidate any warranty.
Note that batteries are electrically live at all times and great care should be taken to ensure that the
terminals are never presented with a short circuit. Care should be taken at all times, especially during
transit, installation and normal use.
Use caution as there is a risk of explosion if the batteries are replaced by an incorrect type.
Batteries no longer required should be disposed of in a safe and environmentally friendly manner by the
battery manufacturer or a suitable recycling service. They should never be incinerated or placed in normal
rubbish collection facilities. Dispose of used batteries according to the instructions.
