That very much depends on whether the device simply sends a signal down a
wire or whatever, or whether it actually controls a relay or something like

As its
a wireless device there's erm.. no wire..

ISTR that these PIRs do "fire" a transmission to the control unit
even when the alarm is notionally "off". So PIRs in busy areas
will tend to drain batts quicker than others.

Time for better batts in the busy locations?
