Micro Seven, Inc. model PC300-32ARC, Custom Alarm Panel Test Unit
PC300-32ARC
is shown with 19-inch rack-mount kit
Introduction
Micro Seven model PC300-32ARC is a custom instrument built
on 32-port alarm receiver PC300-32AR with alarm signal inputs available for
complete alarm panel go/no-go test unit. PC300-32ARC is compatible with the
Ademco ® Contact ID Protocol for Alarm System Communications. One of unique
features of PC300-32ARC is that it contains simulated telephone line like PBX
inside line, and it eliminates needs of external telephone line or PBX lines.
Therefore, alarm panels may be connected directly to PC300-32ARC with telephone
cords. Another unique feature of PC300-32ARC is that loop signals triggering
alarm panels are generated internally. There are four alarm signal inputs
including fire, supervisory, and trouble, which consists of an open-collector.
The input is selected by an internal controller/microprocessor for each line
individually or all lines simultaneously. Tests may be started by manually with
front panel switch or by PC. The front-panel LED indicator for each line
displays whether PC300-32ARC successfully receives all four alarm messages from
alarm panels after triggering all four inputs to alarm panels. The test result of all ports is compiled,
and The entire test of 32 lines is output at RS232 port to PC. Also the test
result is stored in a file.
Custom software, which may be developed by client, may also
be developed by Micro Seven, Inc. to email test result to clients in the
Internet, and the test results are presented in a homepage so that test
engineers and technicians may be able to view real-time test result. However, the definition of the custom
software is beyond scope of PC300-32ARC.

Front-panel switch 1: Run/Stop,
for one-shot test, turn on the switch once and turn it off. For continuous run,
leave the switch in upper position

Service
performed at the factory, usually within ten(10) working days.
Programmable features by control software:
- telephone
numbers, ten different toll-free numbers
- kiss-off
tone duration, The
Contact ID protocol specification requires the length of kissoff tone that
is transmitted by the receiver to be 750 ms mimimum 1 sec maximum.
- Alarm
message length: The
standard alarm message-length of Contact ID protocol is sixteen digits
including the checksum; however, non-standard alarm messages that are
shorter than sixteen digits are acceptable.
- Kiss-off
tone hold: Kiss-off tone
generation may be hold.
Test procedure set by internal controller:
- output fire loop signal for each
of 32 lines, check if it receives alarm messages.
- output supervisory loop signal for
each of 32 lines, check if it receives alarm messages.
- output trouble loop signal for
each of 32 lines, check if it receives alarm messages.
Testing of second telephone line output will be
conducted after the primary telephone line output is tested. The test of second
telephone line may be shortened.
Special cable requirement:
Custom cable from
PC300 to alarm panels for telephone line, loop inputs is required, and it will
be defined later.
