No. Not a false trigger. A hourly trigger... a heart-beat.... and only if in the trigger position. It's a useful feature and part of the security setup.
hmmm.... The DS10A transmit their status (OPEN or CLOSED) about once every 60 minutes. "Open" and "Triggered" mean the same thing. Without movement, the MS10A's report a "reset" condition about every 90 minutes.
The heartbeats tell the DS7000 (security console) that the sensors are alive. When the DS7000 doesn't receive a heartbeat for 4 hours - it lights the corresponding LED to let you know the sensor is gone, dead, too far away, out-of-touch...
Heartbeats will also trigger & re-trigger macros. You can be reminded every hour that the garage door is open. I use the CLOSED heartbeat to ensure all the lights in an area are OFF.
And Dave is correct - without using FLAGs, Phantoms, and CONDITIONS, those heartbeats can cause un-wanted re-triggers, so just plan for them.
