If less than 4 systems/deactivators are installed you may be able to
synchronized using only the SYN trimmer on SDP82 to set each devise with a
different time pulse.
External Synchro Method:
For more than 4 systems/deactivators using a RG174 synchro cable is
recommended:
□ Press SW1 to reset systems.
□ The green LED on the deactivator should be ON.
□ If green LED on the deactivator is bilking, change the SYN trimmer
adjustment on the deactivator.
6. TROUBLE SHOOTING
• False alarms / No detection / Orange/Red LED Noise Bar Level is
blinking fast and with regular intervals:
the most like reason is that another 8.2 MHz EAS system is installed nearby:
□ Put Switch 7 in position ON
□ Reset System
□ Turn SYN trimmer to find the best position
• Sporadic false alarms but with good detection and low LED noise Level:
This problem maybe caused by an external electrical disturbance or resonant
object nearby (metal/swing door…).
□ Turn the SYNC trimmer to find a better position.
□ If the problem persists set the Switch 5 in the position OFF
□ If the problem persists, set Switch 2 in the position ON and change SYNC
trimmer position to reduce random noise burst.
If the problem persists, refer to the pre-installation instruction to find the
possible source of disturbance. (Electrical interference, resonant object…)
• False alarm when touching antenna.
□ Look for possible resonant object
□ Change Antenna adjustment with Antenna Gain Adjustable capacitor.
□ If problem persists, set switch DIP 5 in the position OFF.
□ Reset system.
□ If problem persists switch the system to manual level control mode (switch 7
position OFF)
□ Press SW1 to reset system.
