Abort and Manual Release Switch Wiring
Wiring for the abort and manual release switches is shown in Figures 10 and 11. Depending on the selected mode,
the Abort and Manual release switches can either be on different circuits or they both can be on the same circuit.
When on separate circuits, DET5 is used for the Abort switch and DET6 is used for the manual release switch.
When on the same circuit, DET 5 Abort/Manual release combination is for hazard area 1, while DET6 Abort/Manual
release combination is for hazard area 2. When an Abort/Manual release combination is used, ensure that the
Manual release switch is always before the Abort switch. Also ensure that there is a current limiting resistor (MP-
1500R/W) between the Manual release and Abort switch for differentiating between the two switches.

Note: For the circuit with the combined Abort Switch and Manual Release Switch, a maximum of four Abort
Switches can be connected.
