10 Accessories (Optional)

10.1 Line IN/OUT

Connect the output from your music and paging system to the server using a Y-Adapter Audio Cable (See

Figure 6). Insert the 3.5mm stereo plug (See Figure 7) into the audio connector labeled Line IN/OUT on the

front panel (See Figure 1 item 11). A stereo splitter (not included) is required to use both Music-On-Hold and

Overhead Paging collectively.

Note: The white audio channel is used for music input and the red audio channel is used for paging output

(See Figure 6).

10.2 Terminal Block

The unit comes with two (2) sets of C-form relay contacts for connecting to external devices such as remote

door releases and paging amplifiers. The contacts are rated 30 VDC @1A. Only connect the SELV circuits

meeting IEC 60950-1 / UL 60950-1 OR NEC Class 2 circuits. Loop the bare wires of the paging amplifier

and/or door relay to the devices corresponding screws (NC, COM, NO) on the terminal block, and then tighten

the screws with a screw driver. Additional audio output for paging can be added using the -/+ screws (See

Figure 2, item 13).

10.3 Serial Port

In addition to the contacts on the rear terminal block, door relay contacts are available at the serial port

connector on the front of the unit (See Figure 1, item 5). The contacts are rated 30 VDC @ 1A. Only connect

SELV circuits meeting IEC 60950-1 / UL 60950-1 OR NEC Class 2 circuits.

Warning: Do not exceed the contact rating.

The connector is shared with the serial port (See Figure 1, item 5). The pin-out is shown in Table 8 below.
