ON = Enabled input: the detector is installed, the measurement and the Alarms and Fault relays
are in operation. (
OFF = Disabled Input the detector is absent, the display shows Sx off. Fault relays and alarms do
not intervene. (Can also be used to exclude a faulty detector or removed for maintenance).
SW2 only used to configure the Flammable Gas Detectors
RANGE:
ON = Range 100% LIE, use only if P-type detectors (Pellistor) are installed.
OFF = Range 20% LIE, use only if K-type detectors (Catalytic) are installed
SET
ALARM: the SW2 Dip-Switches / No.2 and No.3 sets up the alarm thresholds.
No.2 and No.3 both OFF = ALARM 1 set to 10%LEL and ALARM 2 set to 20%LEL (DEFAULT SETTING).

LOGIC (of the
Relay): SW2 Dip-Switch No.4 set up the functioning mode of the ALARM 2 relay.
ON = Negative logic, the relay is de-energized, it is used for normally open valves.
OFF = Positive logic, the relay is normally energized, in case of power failure or relay failure, it automatically

MAINTENANCE OF THE PRODUCT
The control unit after the Dip-Switch configuration does not need further adjustment after installation
During preheating of the detectors, which is of about 60 seconds, the alarm relays remain inhibited, while the Yel-
low LED and the
relay are activated.
FAULT
In case of short circuit between the connection cables to a detector, the protection circuit interrupts to it the
power supply.
Both the FAULT relay and the yellow LED will activate.

PAY ATTENTION: This procedure has to be made with extreme attention and by authorized and trained people.;
because starting this procedure it will start both Outputs (relays) causing the activation of connected alarm devices.
The TEST key is disabled if one or more inputs are more than 10% LEL (flammable gas detectors) or 35 ppm (CO
gas detectors).
Instrument operation check: Press and hold the TEST key for 5 seconds until the test procedure will start,

DESCRIPTION
Le CTP25 est une centrale de détection de gaz et pouvant recevoir 3 sondes extérieures, qui peuvent être configu-
rés individuellement pour les gaz inflammables ou toxiques.
Pour gaz inflammables, possédant deux fond d'échelle différentes.
d'échelle de 20% LIE, s'ils sont de type catalytique (K) ou tous avec un fond d'échelle de 100% LIE, s'ils sont de
type Pellistor (P).
Pour le gaz toxique possédant
Le CTP25 est installable en saillie murale son indice de protection est IP65. L'appareil est alimenté normalement en
110÷240Vca / 50÷60Hz mais il peut être raccordé à une alimentation extérieure 24Vcc (exemple à une alimentation
secourue avec deux batteries en tampon 12V-7A/h modèle PS180/24VDC).
