This cartridge (Figure 1) is in-
tended for use with the Models
206 and 410 communications
system, and provides two sepa-
rate functions. When properly
connected to an external
alerting device (e.g., bell or
horn), it provides a loud ringer
for noisy or remote locations.
The alert sounds whenever an
outside line rings. The cartridge
also contains two jacks for
plugging in standard modular
telephones (desk models) that

on the front of the car-
tridge is aligned with the
front panel of the control
unit.

Certain older exter-
nal alerts require a
