Relay Outputs 1, 2 & Fault Relay Volt Free Contacts: NO, NC, COM
Relays 1, 2 and the Fault Relay are derived from
single pole change over ‘volt-free’ relay contacts which are
not fault monitored. The relay contacts are rated at 1A @ 30VDC. All inductive loads should be diode
protected to prevent back EMF. However, if this is not done, the load should be limited to 200mA to reduce
the likelihood of back EMF causing damage to the relay contacts.
The default setting for Relay Outputs 1 & 2 is as
Common Fire
outputs where the relay is energised in the
fire condition.
Relays 1 & 2 can be set as follows:
Not Configured
Fire Output (Common)
Fire Output (Zonal)
Common Fault
The Fault Relay cannot be configured and will always operate as a
Common Fault
output where the relay is
de-energised in the fault condition.
In order to meet the requirements of EN54-2, one relay must be left as a fire output.
