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).

ACTION:
Controlled by panel when it determines
alarm condition has been met.
When FAULT CONDITION on Ch1 or Ch2
or a common FAULT occurs. Fault is also
signalled when in Service Mode and when
the device is unpowered.
Set ON when a channel is in ALARM.
Sounder 1 corresponds to Ch1 and
Sounder 2 corresponds to Ch2

damage the module relay contacts (see above).
T5
To protect the relay contacts, connect a suitable Transient
Voltage Suppressor (for example 1N6284CA ) across the
T6
load as shown.
T7
Alternatively, for unsupervised DC applications, fit a diode
with a reverse breakdown voltage greater than 10 times the
T8
circuit voltage.

NOTES
Set ON and OFF by panel; not latched
Fault state is not latched.
