Operates in the same way as the ATTs Silent Alarm but has a clear underlit two-magnet roller wheel that illuminates in the event of a bite.
Supplied with rubber case.
With its 'intelligent detection system' the alarm knows the roller position in which it was most recently activated, so can eliminate false activation.
Under roller wheel LED.
Alarms Alarms powered by 1 x 4A76 battery (supplied). For replacement battery see product code 10774.
