EDS - RK90R - OPTICAL BEAM SMOKE DETECTOR - USER GUIDE

13 -FAULT OUTPUT

13.1 - the fault relay contact is available on the terminal block of the RX.

This relay is normally activated and will be deactivated if at least one of the following conditions

are verified:

• the output signal falls below the 90% preset value (optical beam completely interrupted by an

obstacle)

• the circuit of autocompensation has reached its limit (when this happens it is necessary to do some

maintenance on the detector)

• operation fault (detectors’s circuit malfunction) Attention: the current standards indicate that the

fault output can be used for remote signaling, but must not be used for inhibiting the alarm signal

14 - ALARM MEMORY AND CONFIGURATION DATA

14.1 - the receiver of the RK100B is equipped with alarm memory that can be activated / deactivated

with the JP5 jumper (fig.9):

• jumper JP5 in position 1-2 - memory deactivated (OFF)

• jumper JP5 in position 2-3 - activated (ON)

When the alarm memory is activated, if the detector gets in alarm, the alarm output relay and the

frontal red led remain activated until the alarm condition gets off and power supply is removed for at

least 5 seconds.

When the memory is not activated, if the detector gets in alarm the alarm output relay and the red

frontal led are deactivated as soon as the alarm condition gets off.

14.2 - memory of configuration and settings data.

In case of lack of power supply the internal memory retains the data.

When the power supply is back the detector, after a setup time of 2 minutes, returns to normal operation

15 - FRONTAL LEDS OPERATION

15.1 - the frontal leds of the RX during the normal operation of the detector, give out the following

indications (see fig.9):

• normal operation: the blue led flashes every 10 seconds

alarm: the red Led lights up

• limit of compensation, interrupted beam, fault: the blue Led flashes every second
