DESCRIPTION
The CTP24 is a control unit for heating plants, or environments to be protected from possible flammable gas leaks.
The unit can be connected up to 4 remote gas detectors. They can be configured, all with a full scale of 20% LEL, if
they are Catalytic (K) type or all with 100% LEL scale, if they are Pellistor type P.
The CTP24 is for wall mounting and the protection code is IP65. It is mains powered at 110÷240VAC / 50÷60Hz but
can also be connected either to an external 24VDC power supply (e.g.
batteries, our mod.
PS180/24VDC).
On the front plate there are, three LED that indicate the operating status, the
tration detected by each remote detector and two
The control unit has two alarm levels with sealed relay outputs (ALARM1 and ALARM2), with tension free changeover
contacts. Furthermore, it is also present another output relay (FAULT) in positive
trol unit has two auxiliary inputs. AUX1 is to connect NO contact devices such as a manual Button. AUX2 is the con-
trol input for our Manual NC Resetting Valve with positioning sensor.

OPERATIONAL DESCRIPTION
Power on: all times the control unit is powered, the display shows the name of the manufacturer, the model and the
firmware version (eg. GECA srl / CTP24 v.1.00).
Language: Then, on the display, the choice of available languages (eg EN-EN-FR) appears, pressing the RESET
key will change the language, pressing the TEST key confirms the choice. If you do not make a choice within 10
seconds, the program continues automatically maintaining the last selected language.
WARNING: the language choice, always appears at each power on, but after 10 seconds the program will automatically continue maintain-
ing the last selected language.
Info: then, always appear in sequence 3 screens with configuration set reminders via the Dip-Switch: SCALE OF
MEASURE / ALARMS THRESHOLD / ENABLED DETECTORS. Then the program continues automatically.
