Single End Of Line (EOL) Resistors

To enable panel detection of single end-of-line resistors, program
section [013], options [1] and [2] to OFF.
NOTE: This option should be selected if either Normally Closed
(NC) or Normally Open (NO) detection devices or contacts are
being used.
The following chart shows zone status under certain conditions
for SEOL:
Loop Resistance
0Ω (shorted wire, loop shorted)
5600Ω (contact closed)
Infinite (broken wire, loop open)

Double End of Line (DEOL) Resistors

Double End of Line resistors allow the panel to determine if the
zone is in alarm, tampered or faulted.
To enable panel detection of double end of line resistors, program
section [013], option [1] to OFF and option [2] to ON.
NOTE: If the Double EOL supervision option is enabled, all hard-
wired zones must be wired for Double EOL resistors, except for
Fire and 24 Hour Supervisory zones. Do not use DEOL resistors for
Fire zones or 24 Hour Supervisory zones.
NOTE: Do not wire Fire zones to keypad zone terminals if the
DEOL supervision option is selected.
NOTE:
This option can only be selected if Normally Closed (NC)
detection devices or contacts are being used. Only one NC contact
can be connected to each zone.
The following chart shows zone status under certain conditions
for DEOL:
Loop Resistance
0Ω (shorted wire, loop shorted)
5600Ω (contact closed)
Infinite (broken wire, loop open)
11200Ω (contact open)

If the PC1616/PC1832/PC1864 is set up for Double
End of Line (DEOL) resistors the panel will detect both Fault and
Tamper (Short and Open) conditions as tamper condition. Keybus
fault and Zone Expander Supervisory will also be detected as
tamper conditions. When a tamper event occurs due to the
tamper switch activation on a wireless device, RF Zone Trouble
Supervisory Fault, or hardwired zones configured for Double End
Of Line supervision, the system will go into an alarm and tamper
condition. There is also a change in the [*][2] Trouble Display
where the meaning of light 5 changes from Zone Fault to RF
Supervisory Fault indication. Trouble light 6 - Trouble Zone
Tamper - will include Fire Zone trouble indication.
NOTE:
condition occurs.
This operation affects the PGM activation. Below is a list of condi-
tions which are treated as tamper events and will activate theBell

Fire Zone Wiring - 4-Wire Smoke Detectors

All zones defined as Fire (see section 5.2 'Basic Programming')
must be wired according to the following diagram:
