Using Programmable Outputs

The Bell and OP2 outputs on the Main Connector provide Negative Applied
or Negative Removed control signals. OP3 provides Positive Applied or
Positive Removed control signals. Note that when using Menu 51 the Bell
output (OP1) is fixed as a Bell output type.

Wiring Keyswitches

Figures 15 to 17 show how to connect two- or three position keyswitches.
Each keyswitch occupies one 2-wire FSL zone connection or one 4-wire CC
connection. This can be any of zones 1 to 8 on the end station Main Con-
nector.
To ensure that the keyswitches work correctly use Menu 32 to program a
keyswitch zone and Menu 41 to allocate the keyswitch zone to a specific
Level (see "4. Programming - Example 3 Keyswitches").
