PASSIVE INFRARED DETECTOR

SL-AL8

INSTRUCTION

              It is a new type of human infrared sensor, it adopts high sensitivity detector and SMD technology. it gathers sense and emission; when one enters its sense range, it sense and emit signal to suited receiver( any receiver of our company). It¡¯s shape is elaborate and good.

FEATURES

  • Battery powered and no wiring required;
  • Preventing false alarm function: it can be set that sense once to emit or sense twice to emit:
  • Sense and emission indication;
  • Low-battery indication: when the battery energy is below 7V, the low-battery LED in crystal board will flash once a second and you should replace the battery;
  • Possessing power switch.

SPECIFICATION

        Power supply: DC 9V Emit distance:¡Ý50m
        Frequency: 315MHzInstallation height:2m
        433MHzSense motion speed:0.6~1.5m/s
        Static current: 30¦ÌA Working temperature: -20~40¡æ
        Sense distance: 12m Relative humidity:<93%RH
        Sense angle:110¡ã

JUMPER SETTING

  • Sense once to emit:

    sense it once,the sensor emit signal, 15 seconds later after it emit signal, sense it once again, it emit signal again;

2.Sense twice to emit.:
after sense it twice, the sensor emit signal, 15 seconds later after it emit signal, sense it twice again, it emit signal again.


TEST

  • Set jumper on ¡°AUTO¡± position;
  • Fix 9V battery, fix the unit on selected position;
  • Turn on the power switch, after 60s it enters stable working state;
  • Move along the lens tangent in the sense field, after sense twice (the sense LED light twice ), it emit signal ( the emission LED on), the emitting time is 3~4s.Note: the interval between the sensing twice shouldn¡¯t exceed 15s.

NOTE

  • Walking test periodically to assure proper operation should check the unit. lf the unit does not work properly, immediately replace the batteries and retest the unit ;
  • Remove the batteries when use not required for a long period of time;
  • Avoid installing the unit on the metal base;
  • No block is allowed between the unit and desired area of detection;
  • The unit and its detection area should not be exposed to direct sunlight, heaters, electric fans, etc;
  • The sensitivity has great relation with the moving direction (like the sense diagram)
