Explanation of combining latching, acknowledgment and
pre-acknowledgment of alarms:
Since the concepts of latching and acknowledgment can be
confusing, the following six combinations are offered for
clarification:
Relay Test
These functions change the status of a relay and LED for test
purposes (e.g. to check the function of alarm devices connected
to the relay) and the symbol [ ] is displayed. After exiting this
function, the status of the relay and LED will automatically return
to their previous status.

parameters).

Latching and
acknowledgeable
Relay must be reset manually and can
be reset before the alarm condition
clears.
Latching and non-
acknowledgeable
Relay must be reset manually. Relay
cannot be reset before the alarm
condition clears.
Latching and pre-
acknowledgeable
Relay must be reset manually. Relay
can be reset while the alarm condition
is still present but relay will not reset
until the alarm condition clears.
Non-latching and
acknowledgeable
Relay will reset automatically when
the alarm condition clears or can be
reset manually.
Non-latching and
non-
acknowledgeable
Relay will reset automatically when
the alarm condition clears. Relay
cannot be reset manually before the
alarm condition clears.
Non-latching and
pre-
acknowledgeable
Relay will reset automatically when
the alarm condition clears. Relay can
be reset while the alarm condition is
still present but relay will not rest until
the alarm condition clears.
NOTICE
For safe operation:
 The relays must be set to “Normally energized” and
the A2 alarm (main alarm) must be set to “latching”
and “not acknowledgeable” or “pre-
acknowledgeable”.
 The A1 alarm (pre alarm) may only be set to
“acknowledgeable” if it is used for triggering an
acoustic alarm device.
NOTICE
When the relays are activated, alarm devices will be
switched on.
