Commissioning
Check that the relay command logic is as required.
Jumper E1
E1 positioned towards A
continuous ON command for relay (factory setting)
E1 positioned towards B
relay impulse command (0,5 sec ON every 10 sec)
Put the power on for the detector, and check that the initial test phase is carried out, which
includes warming up the sensor, as indicated in the functional status table.
8.1
Operating check
1.
To check that the detector is working, simply push the relevant test button, located inside the equipment. The alarm
condition induced by the button activates a functional check of the entire actuation chain, excepting for the sensor, which
is checked continuously by specific electronic circuitry.
2.
Once these tasks have been done, the detector must indicate its alarm status, as follows:
The red LED switches on
The green LED stays on
The buzzer sounds continuously for the entire alarm time.
The relay switches (continuous or impulse) activating any loads connected to it.
The solenoid valve is closed after 15 sec (command impulse for 0,5 sec every 10 sec).
Once the alarm has ended, the detector automatically returns to normal mode.
It is advisable to repeat the operating test at least once a year, or after a prolonged period of stoppage and
in any case, every time the detector is replaced.
CAUTION: The average lifespan of an ESN26.C detector is 6 years, from the date of manufacture.
