CCD 573X
Planning
The country-specific directives apply when planning and installing
automatic fire detector systems.
For combined fire detectors (CCD 573X) additional directives may
apply if one of the detection properties is continuously or temporar-
ily deactivated.
The following table shows all of the possibilities for combining the
modes of operation and the recommended planning directive.

No recommenda-
tion
Under normal ambient conditions an operating time
of up to 7 years is possible; however, it is abso-
lutely necessary that the detector is commissioned
no later than 7 months after the production date
(see product identification).
It is imperative that the maximum permitted ambi-
ent temperature is observed; if not, the CO cell may
be destroyed.
Increased concentrations of hydrogen or alcohol in
the ambient air may cause CO false alarms.
Mounting/installation
Mounting and installation of the CCD 573X is accomplished with
the assembly base series USB 502.
USB 502-1 Standard base for surface mounting
USB 502-2 Base for flush mounting in dropped ceilings
USB 502-3 Base for damp rooms
USB 502-4 Base for flush mounting in concrete
USB 502-6 Standard base surface mounting without loop con-
tact
USB 502-20 Standard base with illuminated ring without loop
contact
The specifications in the data sheets shall apply for installation; de-
tector base series USB 502.
Connection
The maximum number of detectors on an address-
able loop has to be calculated. It must take into ac-
count power consumption, the installation, other
line participants and the applicable directives and
regulations.
The electrical connection in the USB 502 base is with terminal
strips. The electrical connection between detector and base is by
means of a 5-pin plug connector.

Terminal 5 (alarm output) may be loaded a maxi-
mum of 5 mA, 1 mA or 0.1 mA.
The connections of the USB 502 base are designed so that when
the CCD 573X is removed the SecuriLine eXtended is closed.
The USB502-6/USB502-6MC und USB502-20 bases do not have a
loop contact. When removing the detector from these bases, the
SecuriLine eXtended is therefore not closed!
A short-circuit disconnecter in the CCD 573X ensures that a short-
circuit in the installation (loop) is isolated in the area of the dam-
age. This allows the detectors to continue functioning unimpeded.
Exception:
Under the following conditions it may occur that detectors are no
longer recognised on the SecuriLine eXtended:
Detector defect (short-circuit or interruption)
More than one short-circuit or interruption before and after the
detector
Short-circuit or interruption in stub line
