CCD 573X
Smoke, heat and CO detector
The multiple sensor detector CCD 573X is an individually ad-
dressed, combined automatic detector for smoke, heat and carbon
monoxide.
The CCD 573X meets the specifications of the SecuriLine eX-
tended for operation on the addressable loop of the SecuriFire fire
alarm system.

Operation/use
The multiple sensor detector CCD 573X is a combined smoke-,
heat- and carbon monoxide detector. It detects smouldering fires
and open fires early on by detecting and evaluating the fire charac-
teristics smoke, heat and carbon monoxide (CO). Smoke is de-
tected using the Tyndall principle (scattered light), heat is detected
using the NTC sensor principle, and an electrochemical sensor is
used for detecting CO gases. If the signal values preset in the de-
tector are exceeded, the relevant message is sent to the control
panel.
The CCD 573X has a short-circuit disconnecter that can isolate a
short-circuit on the installation.
The CCD 573X can generate the following messages:
Smoke fire alarm (EN 54-7)
Smoke pre-signal:
PS1 at 50%, PS2 at 75% of the alarm threshold
Smoke maintenance alarm
Smoke soiling: Levels 1 and 2
Temperature fire alarm (EN 54-5)
Temperature pre-signal
Temperature maintenance alarm
CO gas fire alarm (EN 54-26/EN 54-30)
CO gas pre-signal
Technical CO gas alarm (EN 50291-1)
Technical CO gas pre-signal adjustable in the range of 20 to
320 ppm (does not correspond to any standard)
CO gas maintenance alarm
Fault messages: Ageing, optical fault, voltage supply fault,
NTC short-circuit and interruption, CO gas sensor fault,
EEPROM memory fault, overtemperature
Key features of the CCD 573X are:
Digital signal processing
Alarm threshold tracking
Temperature-compensated smoke element
Signature alarm for smoke, heat and CO
Temperature-supported smoke evaluation
(CUBUS levelling)
Temperature- and CO-supported smoke evaluation
(CUBUS+ levelling)
Multi-standard use on 3 parallel channels (smoke, heat, CO)
compliant with EN 54-5, -7 as well as prEN 54-26, -29 and -30
Multi-dimensional event memory with real-time information
Fewer false alarms thanks to alarm filters, the use of multi-
sensors, and new signal algorithms
Alarm output voltage 5 V
Alarm output for external alarm display, can be programmed ir-
respective of its own alarm LED as output.
Alarm output power limitation programmable for 0.1 mA, 1 mA,
5 mA
Continuous monitoring of the CO gas sensor
Automatic self-test of all sensors
“Overtemperature” fault
Autonomous short-circuit detection at startup
Works with up to 3.5 km line length
(at 25°C ambient temperature)
The CCD 573X can be system-specifically programmed and ad-
justed to its area of application. The most important setting options
are:
Selection of fire characteristics smoke, heat and CO gas com-
pliant with standards EN 54-5, -7 as well as prEN 54-26, 54-29
and 54-30
Up to three standards-compliant, parallel modes of operation
selectable
Selection of heat class compliant with EN 54-5;
Class A1, A2, B including Index R (for unheated rooms) and
Index S (for kitchens) for all 3 heat classes.
Signalling of a technical CO gas alarm based on EN50291-1
Technical CO gas pre-alarm, adjustable from 20 to 320 ppm
Blinking at function (activatable)
