Ports are programmed with switches or through the use of

downloaded databases, depending on the firmware being used

on the MAP.
Addressing the remote alarm and control devices is done using a

tri-state octal buffer and a tri-state octal D-type latch that forms

three parallel inputs/outpus. Redundant features of each buffer

and latch provide input/output interfaces for an optional 46019

Summary Alarm Module and a unassigned auxiliary input/

output.
The regulated power supply uses -21 to -56 VDC input power to

12 VDC and +5 VDC to the module’s circuit board. The

+5 VDC output also is available at the edge connector for exter-

nal use. In addition, the power supply provides operating power

for an optional communications subassembly.

CIRCUIT DESCRIPTION

INSTALLATION

T

his sections consists of installing the communication subas-

sembly (if necessary), setting the MAP switches, and install-

ing the MAP in the shelf.

Subassembly

The 46020 MAP comes from the factory with a TTL bypass

subassembly installed. Refer to Fig. 2. If a different communica-

tions subassembly needs to be installed, follow these steps:

1.

Remove the hole plug from the front panel of the MAP.

2.

Remove the screws from the subassembly standoffs and remove the

existing subassembly by carefully pulling up on the subassembly.

3.

Install the new subassembly. Examine the connector pins to be

sure that each one goes straight into the socket. The subassembly

should sit down on the standoffs and the front panel should appear

straight in the MAP’s front panel opening.

4.

Install the mounting screws.

5.

Set any straps and/or switches according to the subassembly’s prac-

tice.
