RELAY ACTION: NOTES
ALARM 1 or 2 Controlled by panel when it determines
alarm condition has been met.
Set ON and OFF by panel; not latched
FAULT 1 or 2 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.
Fault state is not latched.
SOUNDER 1 or 2 Set ON when a channel is in ALARM.
Sounder 1 corresponds to Ch1 and
Sounder 2 corresponds to Ch2
Default condition = set on in ALARM.
Table 3: Relays
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).

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, t a diode
with a reverse breakdown voltage greater than 10 times the
circuit voltage.
