Aiphone™ LE / LS series 3-wire Call Station Installation

• Set the internal ST-MIC switch to the ST

setting

• Remove Aiphone shorting link between

E and - terminals

• Connect SPKR 8Ω+ and SPKR 8Ω- (J2-

6 and J2-7) to the "1" and "E" terminals

on the Aiphone call station

• Connect TALK (J2-5) to Aiphone "–"

(minus) terminal

• Connect GND (J2-4) to the shield of the shielded wire. Do not connect the

shield at the call station

Aiphone™ IE / IF series 2-wire Call Station Installation

• Set the internal ST-MIC switch to the

MIC setting

• Connect GND and TALK (J2-4, J2-5)

to Aiphone terminals 1 and 2 (polarity

independent)

• Connect GND (J2-4) to the shield of

the shielded wire. Do not connect the

shield at the door station

Call stations with a separate microphone, speaker and Call button

• Set the internal ST-MIC switch to the MIC setting

• Connect MIC+ and MIC- (J2-1, j2-2) to

the call stations microphone

• Connect GND (J2-4) to the shield of

the shielded wire. Do not connect the

shield at the call station

• Connect SPKR 8Ω+ and SPKR 8Ω-

(J2-6 and J2-7) to the call stations

speaker terminals

• Connect TALK (J2-5) to one contact

on the call station's TALK button

• Connect the other contact on the call station's TALK button to GND (J2-4)

or jumper it to one of the speaker terminals (this wire should be limited to

10ft or 3 meters)

Driving an Analog Paging Amplifier

The IP7-ST/STX has the capability to drive a balanced 600 Ohm input of an

analog amplifier using SPKR 8Ω+ and SPKR 8Ω- (J2-6 and J2-7). Set the

IP7's volume level to 6 and adjust the amplifier's volume control accordingly.

If the analog amplifier uses an unbalanced input, then the IP7's Line

Out and GND (J2-3 and J2-4) must be used instead of SPKR 8Ω+

and SPKR 8Ω-.

Failure to do so will damage the IP7 and void its

warranty.

Relay Options

• The integrated Relay uses COMMON (J3-2), along with NO - Normally

Open (J3-1) or NC - Normally Closed (J3-3). Use Admin Console to

configure the options

Sensor Options

• The integrated Sensor can be used to monitor the status of a door by

connecting Sensor (J3-5) and GND (J3-6) to a contact closure sense

switch. Use Admin Console to configure the options

Power Options

• Power over Ethernet (PoE - 802.3af compliant) - requires 7 watts from

Power Source Equipment (PSE)

• 9VDC - 32VDC external via J1-1 and J1-2 connectors or Aux Power

2.1mm barrel connector

• An external power supply, if detected, overrides PoE power

Network Installation

• Connect an RJ-45 cable between the Ethernet 10/100 connector and a

10/100 network switch

• On the IP7-STx, after the Ethernet 10/100 is connected, another IP device

can be connected to Port 2 10/100 jack

Mounting Instructions

The IP7 series is design to be mounted on standard 35mm DIN rail or

surface mounted using the surface mounting plate.

• DIN Rail Clip – Tilt top of unit (J1, J2, J3 connectors facing up with Volume

buttons facing forward) back towards the DIN Rail until the IP7 DIN clip

catches the top of the rail. Press in at the bottom of the IP7 to snap into

place

• Surface Mount Plate – Snap the surface mount plate in half and secure it

to the back of the unit using the provided screws so that the mounting

holes extend past the edges of the case
