i am making a list of the locations the "inspector test connection" is mandatory to be placed as we are getting alot of contractors question of its presence.
NFPA 13 states that it shall be installed where there is an alarm check valve.
18.104.22.168 The alarm test connection shall be permitted to be installed in any location on the fire sprinkler system downstream of the waterflow alarm.
and as it seems, the NFPA does not identify the locations where the alarm check valve to be installed.
can anyone help in:
1- installation locations for alarm check valve
2- installation locations for inspector test connection.
