Informer-IP Wall Mount Series B (Model I-IPW)
A removable eight-position connector is located on the inside of the Informer-IP for
making electrical connections. The connector accepts 3/16-inch (5 mm) stripped wire,
18-26 AWG.
The 600 ohm audio output responds as the speaker does. Audio comes on with the
speaker and is reset or shut off when the speaker audio shuts off. The output level is
adjustable from 0 to 2.5 V
p-p
into 600 ohms with 1 kHz tone. The audio out is not active
during Intercom sessions. Make electrical connections to the Input/Output connector as
follows.

Ethernet Port
The Informer-IP has an 8-pin Ethernet port for connecting to the Communications
network. The port accepts 42 to 57 Vdc PoE per IEEE 802.3af. Ethernet wire runs must
be less than 328 feet (100 meters) from the nearest network switch. The wired Ethernet
