ig. 7 shows a TBOS and discrete alarms interfaced to an
E-System using several 46020-38 MAPs. Fig. 8 shows a
system using a 46020-38 MAP to report discrete points.

Refer to Fig. 7. An E-System Adapter can interface up to four
MAP addresses using DCP protocol between the master port of
the MAP(s) and the E-System Adapter. The data port of each
MAP is interfaced to remote sites through a MAC. The #1 and
#3 MAPs are communicating through one port of the MAC-12s
using TBOS protocol to the master port of a MAP at the remote
sites.
At the remote sites, each MAP is communicating through
Port #1 of the MAC-12s using DCM protocol to discrete alarm
and control points. You can connect Ports 2-8 to TBOS serial
alarm and control equipment. MAP #4 is communicating
through a MAC-20 with discrete alarm and control points using
DCM protocol.

Refer to Fig. 8. This example application uses one MAP to
process data between an alarm system master or personal
computer, a printer or standard ASCII (VT-100) terminal, and
remote discrete alarm and control points. The 46022-20 MAC is
equipped with a data communications subassembly to interface
the remote MATs and CPMs.

Refer to Fig. 8. The 46019 Summary Alarm Module (SAM)
controls audible and/or visual alarm devices. This module
provides:
♦
TTL (Transistor-Transistor Logic) and/or optically coupled
inputs,
♦
Latching or following mode,
♦
Selectable time-out for quadruple alarm levels.
You can use the 46018 Audible Alarm Module with the 46019 to
provide the audible signal. For more information, refer to the
manuals for these devices.
