switch. If you are using a lock switch, do not connect any other devices to

The 9940 keypad can be connected to an external panic attack button, as
shown in Figure 12. If the panic attack does not contain a tamper switch, link
the pair of "EXT TAMPER" terminals. Separately link both pairs of terminals if
no panic button is used.
