ACTION:
NOTES
ALARM 1 or 2
Set ON when ALARM CONDITION is met
on a channel
Default condition = Level 1. Alarm state is
latched as default. A manual RESET is
necessary to deactivate LED and relay.
PRE-ALARM 1 or 2
Set ON when PRE-ALARM CONDITION
is met on channel.
Default condition = Level 1.
FAULT 1 or 2
When FAULT CONDITION on Ch1 or Ch2
or a common FAULT occurs. Fault is also
indicated when in SERVICE mode and
when the unit is unpowered.
Fault state is not latched (default)
SOUNDER 1 or 2
Set ON when a channel is in ALARM /
PRE-ALARM. Sounder 1 corresponds to
Ch1 and Sounder 2 corresponds to Ch2
Default condition = set on in ALARM.

WARNING: Switching Inductive Loads
Inductive loads can cause switching surges, which may damage
the module relay contacts (see above).
To protect the relay contacts, connect a suitable Transient Voltage
Suppressor (for example 1N6284CA ) across the load as shown.
Alternatively, for unsupervised DC applications, fit a diode with a
reverse breakdown voltage greater than 10 times the circuit voltage
.
Fitting the Terminal Blocks
To insert the terminal blocks into the unit use the following method:
1 Insert a corner of the block into the slot (see
a
).
2 Push the length of the block into the slot until the block ‘clicks’
into place, the 2 upper hooks on the block should be visible
(see
c
).
