[Hai-users] advice on smoke detector monitoring

[Brett Griffin]

The smokes that connect to HAI are low voltage smokes detectors and do meet
the National codes as long as they are listed ul Smokes compatible with HAI.


The code says the primary power source must be 120vac with battery backup.
 This is true with HAI and any other security system with smoke detectors.

The primary power source is 120VAC to power the HAI system, and HAI drops
this down to 12v to the smokes.  The HAI is battery backed up, and will
satisfy the code requirements. UL (typically commercial installs) require
the system to operate on battery for 24 hours and then be able to go through
one full cycle of an alarm before draining the battery.
