Trouble Condition Restoral
The control panel performs the following upon restoral of a trouble
condition:
✔
The trouble LED turns OFF.
✔
The trouble relay driver deactivates. (TB3-5)
✔
If the Trouble was loss of AC power, the control panel will turn
on the AC LED upon restoral.
✔
Clear the display of the trouble message.
✔
Communicate the restored trouble condition to the central sta-
tion.
OFF Normal Reporting
Removing the panel from Normal Mode and placing it into any other
mode causes a transmission of an "off normal" fault message. Returning
the panel to Normal Mode causes a transmission of a "return to normal"
restoral message.
The MS-5012 transmits zone and system status reports to a Central
Station via the public switched telephone network. Two supervised
telephone line connections are made to interface the control panel to the
telephone lines. Two optional 7-foot telephone cords are available for
this purpose. See Figure 3.5-1 for proper wiring diagram.
The control panel supervises both telephone lines for proper voltage. A
delay of two minutes will occur before a fault in either phone line
connection is reported as a trouble. When a fault is detected, an audible
trouble signal will sound, the yellow trouble LED will turn on, the 4
character display will show either no 1 or no 2 (depending upon which
telephone line has the fault. no 1 = Primary Line, no 2 = Secondary
Line) and the trouble condition will be reported to the Central Station
over the remaining "good" phone line.
The control panel comes with line seizure capability provided to both
the primary and secondary telephone line interfaces. Any time that the
control panel needs to make a call to the Central Station, line seizure
will disconnect any local premises phones sharing the same telephone
line.
All transmission to the Central Station will be sent over the Primary
phone line. In the event of noisy phone lines, transmissions will be sent
over the backup Secondary phone line.
