NOTES:
1. For U.S. Installations: Program HTRI-S #1 as Status causing,
which will not cause the DACT to signal but will cause a local
visual and audible signal. It provides a local signaling of AC fail at
the protected premises.
3. Program HTRI-S #2 as Trouble causing, which will cause the
DACT to signal for all common troubles (including AC fail with
reporting delay).
2. For Canadian Installations: Program HTRI-S #1 as Trouble
causing, which will cause the DACT to signal and will also cause a
local visual and audible signal at the protected premises. Program
the DACT to send a Primary Power Failure signal to the receiving
unit when this HTRI-S is active.
