EDS - RK90R - OPTICAL BEAM SMOKE DETECTOR - USER GUIDE

RECEIVER INTERNAL ELEMENTS

P1 - trimmer for the regulation of the signal level. Normally regulated to 50-60% that corresponds to

a signal of 5V at the maximum distance

SW1 - selector for the regulation of the sensitivity of the circuit sensible to Turbulence (heat).

Sensitivity increases from 1 to 4. In position 1, minimum, in position 4, maximum

SW2 - trimmer for the regulation of the sensitivity of the circuit sensible to obscuration

• low sensitivity - alarm level for obscuration at 70%, position 1

• middle / low sensitivity - alarm level for obscuration at 60%, position 2

• middle / high sensitivity - alarm level for obscuration at 50%, position 3

• high sensitivity - alarm level for obscuration at 40%, position 4

V1-V2-V3 - scews for the regulation of the optical block

CN4 - connector for the STS-01 meter (optional)

JP1 - jumper for activate / deactivate the procedure of optical alignment.

To activate the procedure of optical alignment JP1 jumper must be inserted (ON).

To deactivate the procedure of optical alignment and therefore get the detector operational, the JP1

jumper must be disconnected (OFF)

• JP1 position 2-3 (ON)......alignment procedure activated

• P1 position 1-2 (OFF)...... alignment procedure deactivated

JP2 - JP3 - JP4 - jumpers to set the relay contacts, respectively of the alarm relay, turbulence and fault

normally closed NC or normally open NO.

• position 1-2 - output contact normally open NO

• position 2-3 - output contact normally closed NC

JP4 must be in position 1-2 to have the contact closed because the fault relay is normally activated.

The RK100/200B detector is normally factory preset with closed NC contacts. For the alarm relay the

indication of JP2 is valid if JP7 is in OFF position

JP5 - jumper to activate the alarm memory function or to deactivate such function (to get the auto

Reset of the detector)

• in position 1-2 memory deactivated. When it stops the state of alarm the detector him autoripristina

(Auto Reset)

• in position 2-3 memory activated . In case of alarm the shores-bearer remains in alarm until tension

is not removed for 5 second

JP6 - jumper of microprocessor Reset

JP7 - jumper to set alarm relay operation normally powered or not powered

• JP7 ON - alarm relay normally activated (in case of alarm deactivated). In this case the indication of

the jumper JP2 inverted

• JP7 OFF - alarm relay deactivated (in case of alarm activates). In this case the indication of the

jumper JP2 is according

JP6 - jumper to Reset the microprocessor
