Hardware Installation
D. Installing ETP-103 Series Phones
Models ETP-103 and ETP-103V are designed to mount behind an elevator car
operating panel and require connection to a push button with LED capability on the
car operating panel.
1.
Determine the position where you will mount the phone. Be sure the phone
speaker and microphone are placed directly behind the speaker grille in the car
operating panel or mounting surface.
2.
Mark the four mounting holes. Weld four 0.16” diameter threaded studs to these
spots. These studs should form a rectangle that is 7.2”h x 3.0”w. (Note: These
studs are usually pre-welded in place by the car operating panel manufacturer.)
3.
Place the phone onto the studs and secure with nuts.
4.
Plug the RJ11 connector on the cable extending from the unit into an RJ11
receptacle connected to the phone line (red is ring, green is tip).
5.
Connect the Brown and Black wires to the phone activation switch. The Black
wire is the common wire.
6.
Connect a Red wire and the Black wire to the LED. The phone comes with two
red wires, to operate two LED
ʼ
s simultaneously if necessary. (Note: If LED does
not work, reverse polarity.)

. Wiring an ETP-103 or ETP-103V to Elevator "Push to Talk" Pushbuttons
NOTES:
1) Many elevator car operating panel manufacturers "push to talk" buttons
use an LED manufactured by Data Display Products (part number 5SB-RLP2).
One is packed with the unit.
2) When inserting the LED into the button, be sure that the plus side of the LED
is connected to the red wire of the phone.
3) Models ETP-103 and ETP-103V are designed to connect to either one or two
Car Stations (i.e., one on each side of door). If you are only connecting to one
button, tape up the second set of wires to prevent shorting.
4) At the Branch's discretion the "alarm" push button can be used in lieu
of the "push to talk" pushbutton.
5) The above applications MUST be approved by the local code authority inspector.
