The
DISCOVERY
W
wireless
PIR
is
an
advanced microprocessor-
controlled, low-current PIR detector incorporating an on-board
miniature UHF transmitter.
Following detection, the DISCOVERY W activates the on-board
UHF transmitter for 2 seconds, then disarms itself to save battery
power. The detector rearms itself (reverts to the ready state)
automatically 2 minutes after the last movement has been
detected. A TEST/NORMAL selector is used to override the
2-minute rearm timer during walk testing.
A feature summary of the DISCOVERY W detector is given
below.
