The alarm box has three functions:

designated alarm setting has been breached. This
feature can be enabled/disabled manually by opening
up the alarm casing and switching the link. (see
diagram on next page).
2. It can also be connected to an alternative external
alarm e.g. a fl ashing light or a horn. This can be done
through the external alarm wiring terminals provided
(see diagram on the next page).
3. It has an External Lockout function. When an external
lockout function is sensed in control mode (e.g.

all control and dosing. The external lockout terminal

alarm box (See diagram on the next page).
