7-3
Using one pair twisted #24 AWG (0.5mm) or #26 AWG (0.4mm) jumper wire, cross-connect each
add-on module (AOM) to a DLI port (Figure 7-6a
or 7-6b) or plug into the keyset daughterboard
of your choice (see Chapter 9
). If an AOM is to operate as a stand-alone unit, there is nothing
else required other than assigning soft keys. When an AOM is to be used with a station, it must
be assigned to that station in MMC 209. Add-on modules can be assigned to any keyset or sin-
gle line telephone.
CAUTION: To reduce the risk of fire, use only #26 AWG (0.4mm) or larger
telecommunication line cord.
Single Line Telephones
Using one pair twisted #24 AWG (0.5mm) or #26 AWG (0.4mm) jumper wire, cross-connect each
single line telephone (SLT) to the SLI, 8SLI, 8MWSLI, 16SLI or 16MWSLI port of your choice
(Figures 7-7a to 7-7d) or into the keyset daughterboard of your choice (see Chapter 9
).
CAUTION: To reduce the risk of fire, use only #26 AWG (0.4mm) or larger telecommunication
line cord.
SLTs with message waiting lamps must be connected to the 8MWSLI or 16MWSLI card
Door Phone and Door Lock Release
Using one pair twisted #24 AWG (0.5mm) or #26 AWG (0.4mm) jumper wire, cross-connect each
door phone interface module (DPIM) to the DLI port (Figures 7-8a
and 7-8b) or plug into the
keyset daughterboard of your choice (see Chapter 9
). Next, connect the DPIM to the door phone
using #24 AWG (0.5mm) or #26 AWG (0.4mm) twisted pair wire.
CAUTION: To reduce the risk of fire, use only #26 AWG (0.4mm) or larger telecommunication
line cord.
When a customer-provided electric door release is installed, cross-connect the corresponding
door release contacts on the DPIM to the door lock mechanism (Figures 7-8a
and 7-8b). Use
MMC 501 to program the duration of the contact closure as required. The door release contacts
on the DPIM are to be used for low voltage relay control only. The contacts are rated at 24 VDC–
1 amp.
WARNING: Do not attempt to connect commercial AC power to these contacts.
