4. Installing Alarm
•
These are mains powered alarms, so isolate the mains supply before commencing
instal-
lation. They are for installation by a qualified electrician in accordance with the
current I.E.E. regulations.
• Select suitable location having regard to earlier advice.
• Bring house wiring through a dry lining box or Kidde Fyrnetics Surface Mount
Pattress[SMK23]into back of alarm; side entry, via mini trunking is also possible by
carefully knibbling away edge on terminal block cover. Make good joint, with white
sealant, if necessary.
•
If alarm is not being interconnected, interconnect cable terminal (I/O) on alarm is unused.

• Care should be taken not to overtighten terminal screws, as when screwing down the
base of the terminal opening is pulled up around cable, as in Figure c1; This terminal
does not use a grub screw type connection.
• Wire in house cabling to appropriate terminals after prying off terminal cover block,
ensuring that the minimum space possible is taken up by incoming cabling, other-
wise terminal cover may not shut; this then prevents alarm from properly locating on
base. (See figure d, showing too much cable). The
illustration below omits earth (CPC) cable for sake of clarity, and to comply outer
sheathing must remain where cables come through ceiling.
• If necessary the alarm can be unclipped from its base plate

, by depressing where
shown(Figure b) and just the base installed, at 1st fix.
The alarm can then be slid on to the hinge, and then slid home as illustrated below
