Description of the connections

Siemens Building Technologies
Fire Safety & Security Products
Make the necessary connections to the XTU referring to the diagrams in Section
9.4.1: XTU connections - coaxial (C-type) telemetry, Section 9.4.2: XTU
connections - RS485 (D-type) telemetry, and Section 9.4.3: XTU connections -
Photon telemetry, depending on your installation, the markings on the XTU PCB
and the connection list below.
These connections will vary between each installation, and as such there will be
varying requirements for the number of connections, connection type and sealing
requirements. It is the installer's responsibility to ensure that the correct cable
glands are used for the cable type utilised to provide a weatherproof seal. The IP
class of the cable glands used for cable entries should be higher or the same as
that of the enclosure (IP67).
A selection of cable glands are supplied with the XTU:
1 x M20 standard IP68 cable gland - for cables with diameter 10-14 mm (tighten
to 3.3 Nm for IP68).
1 x M20 special IP68 cable gland - for use with the Dome connection cable
(tighten to 3.3 Nm for IP68).
2 x M12 standard IP68 cable glands - for cables with diameter 3-6 mm (tighten
to 1.7 Nm for IP68).
Cable ties are also supplied with the XTU to be used to provide additional strain
relief for the cables by securing them to the punched out anchors in the XTU
mounting plate.
NOTE
All wiring to the XTU should be carried out by a qualified installer and conform to local regulations.
AC input [REQUIRED]
Must be 110-230 V AC, use the strain relief to secure mains cable.
A readily accessible disconnect device shall be incorporated in the building
installation wiring.
This device must be earthed.
As part of the installation protect this device via a 3 A fuse or 3 A circuit breaker.
Coax cable to controller [REQUIRED]
Connect to the controller, video and C-type telemetry pass through this connection.
The cable should be a 75 Ohm CCTV cable URM70, RG59, CT125, etc.
NOTE
The higher the quality of the cable, the further the XTU can be from the controller whilst maintaining
good video quality.
