The SL-1 telephone can have up to six additional key strips (for example, six
QMT1 modules, or two QMT1 and two QMT2 modules). However, the
number of additional key strips that you can add may be limited by other
equipment that is connected to the telephone. A full description of equipment
that can be added to an SL-1 telephone, along with their limitations, is
described in Meridian 1 telephones description and specifications
(553-3001-108).
The QCW-type attendant console accommodates one QMT2 or two QMT1
modules.
When the M1250 or M2250 attendant console is delivered from the factory,
the QMT2 option switch is OFF. To turn the switch ON, you must open the
attendant console (see Procedure 6).
Each telephone that has a key/lamp module installed requires a 25 V ac
power supply.
Procedures 33, 34, 35, and 36 describe how to connect and disconnect add-on
key modules. Tables 20 through 23 give switch settings for the various
applications of add-on modules. Table 24 gives the jack numbering for
add-on module connecting.
See Figure 25 as a reference for the removal and installation of the QMT1 and
QMT2 add-on module faceplate.
