6.   Drill four holes at the scribed mounting hole locations. Remove all burs and sharp edges.   

Secure the housing to the surface with user-supplied hardware.

7.   Attach the conduit to the enclosure. Feed the wiring through the conduit and bring it into the 

enclosure.

8.  Re-install and secure the motherboard to the bottom of the enclosure with the four screws 

removed in step 4. Wire the unit as described in Section E.

9.  After completing the wiring, reinstall the speaker amplifier and power supply modules into 

the receptacles mounted on the motherboard and secure with the screws removed in step 4. 
Plug-in the handset amplifier connector cable at CN1 and secure with the two screws. Re-
install the enclosure cover and secure with the four screws removed in step 3.

C. Panel Mount SelectFone Station Installation

The panel or flush mount intercom station consists of a panel mount handset unit and a remotely 
mounted subset unit. The subset unit consists of a handset amplifier, speaker amplifier, and power 
supply in an enclosure.
The panel mount handset assembly incorporates a black, impact resistant, Cycolac®handset with 
noise canceling dynamic microphone, black cradle with proximity sensor hook switch, and a 
channel selector switch. It has a push-to-page switch located in the handset handle, an “off hook” 
indicator LED, and a 10 ft cable with 25-pin D subminiature connector. To install the panel mount 
unit follow the steps described below:

1.   Install the subset enclosure within 10 ft of the panel or flush-mount unit as described in Sec-

tion A and make electrical connections as described in the Section E.

2.   Locate the handset assembly approximately 54" from the floor in an area where the wires and 

cable are free from interference. Ensure that the back of the panel is closed. 

3.   Using the template (see Figure 3) provided with the panel-mount handset assembly, make a 

rectangular cutout in the panel. Drill four holes in the panel to mount the handset assembly.

4.   Pass the 25-pin D-subminiature connector through the cutout in the panel and anchor the 

handset assembly to the panel with user-supplied hardware.

5.   Plug the 25-pin D-subminiature connector at the end of the cable to the 25-pin receptacle of the 

remotely mounted subset unit and fasten it with the two screws provided on the connector.

D. Desktop Station Installation 

The SelectFone desktop station is similar in construction to the panel mount station. This station 
consists of a desk top handset assembly and a remote subset unit. The subset unit consists of 
the motherboard, the power supply module, the speaker amplifier, and the handset pre-amplifier 
board housed in an enclosure. The remote subset cover has a 25-pin D-subminiature receptacle 
to receive the connector from the desktop assembly.
The  desktop  unit  incorporates  an  impact  resistant,  Cycolac®

 

handset  with  noise-canceling 

dynamic microphone and a channel selector switch. It has a push-to-page switch located in the 
handset handle, an “off hook” indicator LED, a page receive speaker with volume control, and 
10-foot cable with 25-pin D-subminiature connector. To install the desktop unit, follow the steps 
described below:

1.   Install the remote subset enclosure within 10 ft of the desktop handset unit as described in 

Section A and make electrical connections as described in the Section E. The suggested loca-
tion for a remote subset with desktop unit is the knee-well of the desk.

2.   Plug the 25-pin D-subminiature connector to the 25 pin receptacle of the remote subset and 

fasten it with the two screws provided.

3.   Test the station for proper operation.
