Aiphone NH-2SA-AC-2L Instruction Manual
The NH-2SA-AC-2L is modified from the NH-2SA-AC, and provides individual LED indication of which call cord
placed a call. The green LED on the left will light when a call is placed from the NHR-8A plugged into the left jack.
The red LED on the right will light when a call is placed from the NHR-8A plugged into the right jack. There will be no
LED indication when the master station answers the call. (Green TALK LED on a standard station.)
NOTE: An NHX system installed with an NH-2SA-AC-2L included does not carry the UL 1069 listing.
