SYSTEM
ACCESSORIES
Figure 1-8 shows several of the MERLIN II system
accessories described here.
●
Alerter Accessories.
Devices such as a horn, bell,
strobe, or chime can be connected to a Supplemental
Alert Adapter so that people working in noisy or
remote areas of a building can be alerted to incoming
calls.
●
Attendant Intercom Selector.
Can be attached to a
34-Button Deluxe voice terminal when a MERLIN
system has more than eight lines or more than 20 voice
terminals. A system attendant can use the selector’s 30
buttons to access up to 120 Auto Intercom numbers.
The light beside each button indicates whether a voice
terminal or basic telephone is busy and whether a
voice terminal’s message light is on.
●
Auxiliary
Power Unit. This unit must be added to the
control unit if the total number of voice terminals and
voice terminal accessories (including Hands-Free
Units and Headset Adapters) is greater than the control
unit’s power capacity. The control unit supports up to
45 unit loads, and each Auxiliary Power Unit adds 20
unit loads to the system.
●
Basic Telephone and
Modem Interface.
The BTMI
connects telephones and data communications devices
such as autodialers, answering machines, cordless
telephones, facsimile machines, and modems to the
MERLIN II system. A timer may be connected to a
BTMI for automatic answering based on time of day.
The BTMI is no longer available, having been
replaced by the BTMI-2. The BTMI supports more
features than the BTMI-2, however, including the
Conference and Drop features, and line selection. For
customers who already have the BTMI, it can be used
with MERLIN II systems with Feature Module 1,
Feature Module 2, and Release 3.
