Has it been configured to light up its little LED? Wireless PIRs can be
configured either way (you need the LED for walk tests and so forth) but
they should normally be configured off to preserve the batteries. I have
a fully wireless system and the batteries easily last a year.

I am not aware of being able to configure it to off (I will check that),
having said that it will flash when the battery is low.
The LED does not normally flash when the alarm system is not armed.
