4. Installing the Alarm
• These are mains powered alarms, so isolate the mains supply before
commencing installation.
They are for installation by a qualified electri-
cian in accordance with the current I.E.E. regulations
(See section 7 if
interconnecting additional alarms).
• Select suitable location having regard to earlier advice.
• Bring house wiring through a dry lining box or Kidde surface pattress,
(SMK 23) into terminal block (not included).
• If wall mounting, connect supply through a 3 amp fused spur into
Kidde surface pattress SMK 23.
• Site the alarm at least 1.5m above the floor. When sited in same
room as an appliance, the alarm should be sited no closer than 1.8m
from the appliance.
• The appropriate power source is 230V AC power supply from a non-
switchable circuit, which is not protected by a ground fault interupter.
• When alarms are interconnected, all interconnected must be
