FUNCTIONS
1. PULSE COUNT functions to trigger the unit based on desired number of pulse.
1) Select number of pulse, either 1 or 2, using Dip switch 1.
2) The unit will be triggered when pulse count within 10 seconds reaches the specified number. Count will be reset 10 seconds
after the last pulse.
Usually 1 - 3 pulses are counted when human body crosses a field of view. However, there may be a case where
only one pulse is counted when temperature difference between human body and stable background is small.
Please take this into your consideration for appropriate setup.
2. ALARM MEMORY functions to identify the triggered detector(s) when two or more units are connected in one loop.
1) Appropriate wiring with Memory terminal is required.
2) Alarm output will be memorized when both terminals are disconnected.
3) LED will light to indicate the memory while both terminals are connected.
4) Memory will be reset and the LED will be turned off when power is cut off or both terminals are disconnected.
3. SELF-DIAGNOSTIC CIRCUIT functions to detect malfunction of the unit itself.
1) This will function anytime regardless of setup and condition of the unit.
2) LED will flicker to indicate malfunction with terminals or amplifier.
3) Flickering LED and alarm output will continue until power is cut off.
4) LED will flicker regardless of condition of the unit during 30 second warm-up.
