Field Devices
The following paragraph provides the step-by-step procedure
to replace field devices into the
PEGAsys
system.
NOTE:
Smoke and heat detectors can be replaced without
powering down the system. If adding new loop devices
to the system, then the panel will need to be powered
down.
NOTE:
If device is in alarm, the alarm must be cleared prior to
removal from the system. If the alarm cannot be cleared,
remove the device from the system and push the hard
reset on the CCM motherboard and RX/TX. Once the
system is on-line insert the replacement device onto
the loop.
a.
Identify the defective device to be replaced.
b.
Remove the defective device from the PC Line.
c.
Record the Model Number and Device Type.
d.
Ensure the new device is an exact replacement. Verify that
the Model Number is the same as the defective device.
e.
Set the address of the new device to the same as the de-
fective device using the procedure in Paragraph 2-8.6.
f.
Connect the new device to the PC Line where the defec-
tive device was removed, if not accomplished in the previ-
ous step. Use the same detector base or electrical box of
the defective device.
g.
Perform the appropriate test listed below:
•
Loop Device Test (Paragraph 4-3.2) for Detection De-
vices.
•
Walk Test (Paragraph 4-3.4.2) for AI or AO.
