Wire-Connected Connection Of Several Smoke Alarms - Conrad Electronic RM100B868P1 Bedienungsanleitung

8. Wire-connected connection of several
smoke alarms
Some mounting locations allow no or only poor radio reception. This can be
caused, for example, by the type of construction of the building (reinforced
concrete, metal-dampened insulation glass windows, metal doors etc.). In this
connection, observe also the section "11. Information about radio range", page
52.
To be able to trigger he alarm in case of a fire with the development
of smoke, the smoke alarms can be connected with one another
by cable.
On a cable connection, the alarm of a smoke alarm can be passed on apart
from this over large distances (for example, from ancillary buildings, garages
etc.). A connection to any existing "RM100" smoke alarms without radio is
possible at any time in this manner.
A twist, two-lead line can also be used as connecting cable (e. g. the type of
cable J-Y(ST)Y2 x 2 x 0.6mm or a similarly rigid installation cable). In the ideal
case, a total length of cable of up to 400m is possible.
Up to 40 smoke alarms of the type "RM100" can be connected to one another
(any number is possible for a radio connection!).
Proceed as follows to for the connection of the cable:
• First of all, remove any batteries inserted in the smoke alarms.
• In the case of surface-mounting of the cables (e.g. in the garage or an
ancillary building, the lower bulb of the smoke alarm is to be mounted by
means of the enclosed spacers so that you can lay the cables under the
smoke alarms and to conduct them into the inside of the housing. Otherwise
the cables can be damaged/squeezed.
• Conduct the cables through the opening of the lower bulb and fix them at
the desired length with a cable tie to the bracket of the lower bulb (see figure
4 on page 39).
Do not cut the cable too short! Replacing the batteries is only
possible with difficulty then.
