Single End Of Line (EOL) Resistors

To enable panel detection of single end of line resistors, programming section [013], options [1] and [2] must be OFF.
This option should be selected if either normally closed (NC) or normally open (NO) detection devices
or contacts are being used .

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, programming section [013], option [1] must be OFF
and option [2] must be ON.

Fire Zone Wiring - 4-wire Smoke Detectors

All zones defined as Fire (see Section 5.1 "Zone Definitions" ) must be wired according to the following diagram:
For a complete description of how fire zones operate, see Section 5.1 "Zone Definitions".
2.9.5

2-Wire Smoke Detectors

The following 2-wire smoke detectors may be used: ESL429AT and DSC MN220. If PGM2 has been programmed for a
2-wire smoke detector connection, the detectors must be wired according to the following diagram:
T I N G
If the Double EOL supervision option is enabled, all hardwired zones must be wired
for Double EOL resistors, except for Fire and 24 Hour Supervisory zones.
Do not wire DEOL resistors on keypad zones.
Do not use DEOL resistors for Fire zones or 24 Hour Supervisory zones. Do not wire Fire
zones to keypad zone terminals if the DEOL supervision option is selected.
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.
