4. Installing the Alarm
•
These are mains powered alarms, so isolate the mains supply before commencing
installation. They are for installation by a qualified electrician in accor-
dance 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 at a horizontal distance between 1m and
3m from the appliance. In rooms with no appliance,site approximately at face
level; in the lounge this would be at face level when seated; in the bedroom it
would be at face level whenever you lie down.
• The appropriate power source is 230V AC
power supply from a non-switchable circuit, which is not protected by a ground
fault interupter.
