2.9 External Alarm and Lockout Box

The alarm box has three functions:

1. It has an Internal alarm that sounds when a

designated alarm setting has been breached. This
feature can be enabled/disabled manually by opening
up the alarm casing and moving the link (see diagram
on next page)

2. It can also be connected to an alternative external

alarm e.g. a horn or fl ashing light. This can be done
through the external alarm wiring terminals provided
(see diagram on next page).

3. It has an External Lockout function. When an

external lockout function is sensed in control mode
(e.g through a water fl ow switch) the Dosetronic will
stop all control and dosing. The external lockout
terminal can be accessed on

the circuit board found inside

the alarm box

(See diagram on next page).
