-Cc. RPMs -
ACTION
Check that the DIP switches are set correctiy.
If only left bops are being used, make sure program fields ‘06, ‘07, ‘08,
1’10,1*11,1’12, and 1’13 are programmed as -0..
If both left and right loops are being used, make sure program fietds ‘06,
l
07, ‘06, 1’10, 1’11, 1’12, and 1’13 are programmed with “O’s for the
teft loops and ‘1% for the right loops. NOTE: On a 4190WH you cannot
use a right bop unless the left bop is used also.
Check polling loop voltage at the control as well as at each RPM. There
should be fluctuating 6-1lVDC on the loop. If there is no voltage or
steady voltage, check that the 4152LMB is not shorting against the dialer
board (there should be “fish paper installed in between these boards).
Check if programmed for tamper detection in program field ‘24. lf ‘24 L 0,
the RPM will come up in trouble when its cover is removed (4190WH
only).
If a 4206 is being used for zones 1 O-l 7, program field ‘66 must be set for
‘l‘, and the DIP switches should be set as follows: 1,2,3,4, = ON, 5 =
OFF. If any other 4206 configuration is being used, field ‘86 must = -0
and the DIP switches set according to the instructions accompanying the
4208.
If using a 419OWH, make sure that the jumpers are set up in accordance
with the EOLR being used on the left loop (the right loop never uses an
EOLR). See the SYSTEM CONFIGURATION: ZONES section for proper
use of these jumpers and EOLRs.
If using a 4208, make sure the zones are set up with the correct EOLRs.
See the SYSTEM CONFIGURATION: ZONES section for 4208 usage.
If using a 4196 right loop, make sure only closed-circuit devices are used,
and check the program fields ‘06 through ‘08, and 1’10 through 1’13 to
make sure the zones in question are enabled as right loops (‘1”).
This indicates that a ‘short. has been detected on the polling loop.
Check that polling loop polarity is correct at the control as well as at each
RPM.
D&on&t the polling loop from the 4152LMB and check for continuity
from the posltive (+) side of the loop to ground. There should be no
continuity to ground. lf there is a ground, the source must be found and
eliminated.
Check program fields 1’19 through 1’25 to make sure that the zones in
question are not enabled as RF zones.
Make sure each zone in question has been programmed for a response
in fields ‘02~-05 and 1’01-1’05.
Check program fields ‘06 through ‘08, and 1’10 through 1’13 to make
sure that right loops are enabled for the correct zones. If no right loops
are being used, these fields should = ‘0’.
Check program field
l
05 to make sure there is a zone type response
entered for ‘97”. If a polling loop short occurs and no response is
entered for 97. the display would indicate ‘NOT READY” with no
explanation.
