● Alarm memory function

Memory indication function enables identification of individual sensors in multiple sensor on configuration. After raising an alarm, the memory indication LED blinks for 3 minutes and then lights for 47 minutes.

● Day/night time discernment function

By adjusting operation mode control switch, output operation can be controlled according to ambient light level. Selectable for night time only. (5 lux – ∞ lux)

● Output time set up

Time of detection output operation can be adjusted by a switch [off delay selectable approx. 2 sec. – 1 min. or approx. 5 sec. – 10 min.]


*2 sensitivity settings High & Low
*4 detection timer settings : 1 sec., 6 sec., 15 sec., 30 sec.
Possibility of false alarms can be reduced. The set up can be selected from the 8 levels according to the environment of installation. Area masking enables elimination of unnecessary detection areas.

Aesthetically pleasing white housing blends well with most surroundings. The unique ball lock mechanism allows for adjustment of the detection area after installation.
