3.4 How to install the MTS4 into the outdoor enclosure,
continued
Procedure,
continued
Step
Action
14
The door sensor of the MTS is disabled
by disconnecting the small black plug.
Instead the door sensor cable from the
outdoor enclosure,
marked “door sen-
sor”, is connected.
15
In case a smoke detector has been or-
dered, there will be a Wire marked
“Smoke detector” fixed inside the enclo-
sure. This cable should be connected to
the ATCC output on the lower PSU in the
MTS4.
In case this output on the PSU is already
used, you need to connect the existing
plug to the spare plug on the Y-cable wir-
ing from the smoke detector and then
connect the Y-cable plug into the PSU
output socket.
16
In case a LVD relay has been ordered
there will be a w
ire marked “LVD”. This
cable should be connected to the POW-
ER output on the lower site controller in
the MTS4.
Similar to the smoke detector connec-
tion, you need to connect the existing
wire to the spare plug on the Y-cable wir-
ing from the LVD relay and then connect
the Y-cable plug into the PSU output
socket.
LVD (Low Voltage Disconnection) is a re-
lay function that will protect against de-
structive discharge of the backup batter-
ies.
