4.4 Wireless Transmission Timing
The wireless transmissions are timed to optimize battery life.
The indoor alarm display will respond within 3 seconds to a
change in alarm state after wireless communications have been
established. The indoor alarm display receives an update from
the outdoor transmitter every 3.5 minutes. It will take 10 minutes
for the indoor alarm display to indicate that no wireless signal
has been received (yellow steady) after the battery has been
removed.
5. MAINTENANCE
