DHS Installation
5. Terminate the other end of the cable on an industry standard 66M1-50 block for
interconnection to the loud bell and power source.
6. Terminate the Loud Bell and power supply leads on an industry standard 66M1-50
block.
7. Using cross-connect (jumper) wire connect each of the three LBC components
(contact, bell and power source) in series fashion.
14. 2-Port Analog Adapter
The 2-Port Analog Adapter is used to connect analog SLTs and other analog devices to
the system. The analog device must provide DTMF (touch tone) signals in order to make
intercom calls, access outside lines and to activate system features. Some examples of
analog devices are: telephone answering device (TAD), facsimile machine (FAX) or
modem.
The 2-Port Analog Adapter is designed for installation at the MDF but may be positioned
anywhere along the cable path between the KSU and the SLT (or other analog device).
1. The 2-Port Analog Adapter is contained in a wall mount enclosure with pre-drilled
flanges for simple mounting. Properly mounted, the hinged cover will open upward
and lock into position for servicing.
2. Inside the enclosure, the 2-Port Analog Adapter Printed Circuit Board (PCB) is seen
with three RJ-11 modular jacks along the bottom edge of the PCB. One oriented
toward the right side of the 2-Port Analog Adapter PCB is labeled IN. The other two
jacks are labeled OUT1 and OUT2.
3. Extend each of these jacks to the MDF using modular cords and terminal blocks.
4. Once on the MDF, connect the IN jack to the desired digital station port to be used for
analog device interface. This connection requires that the green and red wires
(White/Blue pair) be used.
5. The modular jack OUT1 is now operational as an analog device port with the same
station number that would have been used by a digital key telephone connected to
this port.
6. The modular jack OUT2 is also now operational as an analog device port with a
station number assigned from the upper range (B2 voice channel). The number
assigned is from (58-81). Determining the number is done by association; if the B1
voice channel station number connected to the 2-Port Analog Adapter is 11, then the
The LBC output on the KSU provides only interrupted dry contact closure during the ringing
period of incoming CO Lines.
Relay contact on DHS are rated at 24V DC 1.0 amp. Do not apply AC voltage to these
contacts.
The 2-Port Analog Adapter is not an OPX device as determined by FCC Rules. Additional
equipment is required to support OPX lines. The Analog Adapter will not support Message
Waiting Indication for SLT devices. The Analog Adapter will supply Stutter Dial Tone to the
user.
Do not exceed the maximum cable length from KSU to SLT regardless of where the 2-Port
CO Module is installed.
