Short circuit isolators
Each of the sounder beacons in this range contain an integral
short circuit isolator, which operates between the - VE COM IN
terminal and the -VE COM OUT terminal. (see base wiring
diagram overleaf).
The isolator operates in conjunction with Eaton Control Panel
when a low parallel resistance fault of typically 200 is presented
between the +VE and -VE of the loop wiring.

(i) Knock-Out the required fixing holes
(ii) Fix to mounting surface using
two suitable screws
If the base deforms on an uneven
surface, loosen the screws or move
to a more flat position.
(i) Clip Sounder onto base
If sounder needs to be removed
use a small screwdriver to unclip
Do not bring excessive cable into
the sounder/beacon as this can
interfere with the fitting of the
detector, keep cable tails to
a minimum.
Fit the locking tab into the square hole
on the sounder.
Finish assembly as stage 5.
Remove by inserting a
suitable tool (eg screwdriver)
into the hole in the detector /
cover, the rotate detector /
cover anti-clockwise.
WARNING Do NOT use high
voltage testers if ANY equipment
is connected to the system.
Earth screen must be continuous
along entire length of loop.
