EDS - RK90R - OPTICAL BEAM SMOKE DETECTOR - USER GUIDE
18
13 - FAULT OUTPUT
13.1
- The contact of fault/malfunction relay is available on the terminal block of the detector . This
relay is normally activated and will become deactivated if the following conditions are verified:
• the signal drops below the 90% setup value (optical beam completely interrupted by an obstacle)
• the circuit of autocompensation has reached the limit (when this happens to proceed it is necessary
to the maintenance of the detector)
• malfunction (it means breakdown of some component)
Attention
: As stated by the relevant standards, the fault output can be used for remote signaling, but
must not be used for inhibiting the alarm signal.
14 - ALARM MEMORY
14.1
- the RK90R is equiped with an alarm memory that can be switched ON/OFF with the jumper JP5
(fig.9):
• jumper JP5 in position 1-2 - memory not activated (OFF)
• jumper JP5 in position 2-3 - activated (ON)
When the memory is activated, if the detector goes in alarm, the Alarm relay and the frontal red led
remain activated until the alarm condition disappears and the power supply is not switched off for
more than 5 seconds. When the memory is not activated, if the detector goes to alarm, the alarm relay
and the frontal led are deactivated as soon as the alarm stops.
14.2
- Memory of configuration and settings data.
In case of black out the memory inside preserves the data. When the power supply is back, the detector,
after an initialization of about 2 minutes, returns to normal operation.
15 - FRONTAL LEDS OPERATION
15.1
- The frontal leds of the detector, during the normal operation, give the following indications
(v. fig.9):
• normal operation: the blue Led flashes every 10 seconds
• alarm: the red Led is constantly ON
• limit of compensation, interrupted beam, malfunction: the blue led flashes
