3.1 Test button
The TEST button provides a means to test most of the monitor circuitry.
Briefly pressing the TEST button simulates an alarm condition. The
audible and visual indications will warn as long as the user is pressing
the
TEST button.
3.2 Alarm indications
Audible
The audible alarm is sufficiently loud for most indoor applications. An
external alarm indication, audible and/or visual, is recommended when
the SMARTS II is located in an area with significant ambient noise.
When the SMARTS II detects radiation at its preset alarm threshold or
higher, a continuous audible alarm is generated.
Visual (LED indicator)
The red LED indicator flashes approximately every forty seconds
whenever the SMARTS II is functioning normally.
When the SMARTS II detects radiation at its preset alarm threshold or
higher, the LED indicator flashes for 10 ms every second.
