Wireless locks are NOT appropriate for lockdown systems. This is because a wireless lock only communicates to the head end every 2 to 5 minutes in order to determine if it needs to lockdown. It operates this way in order to save battery life. A lockdown command needs to be received instantaneously in order to protect lives in an emergency. There are some new wireless locks that keep the communication line open all the time for an emergency lockdown command. This new type of wireless lock is appropriate for the application, but still is not as reliable as a hardwired system.
