FlameGard 5 UV/IR-E
RELAY OUTPUT (Figure 3-E)
A1 ALM
Description: This connection is the WARN relay contact. The WARN output is immediate
and can be normally energised or normally de-energised, latching or non-latching.
WARN relay contact rating is 1A @ 30VRMS/42.2VPK Resistive.
A2 ALM
Description: This connection is the ALARM relay contact. The ALARM output is time
delayed for 2, 4, 8 or 10 seconds. The ALARM output can be normally energised or
normally de-energised, latching or non-latching.
ALARM relay contact rating is 1A @ 30VRMS/42.2VPK Resistive.
FAULT
Description: This connection is the FAULT relay contact. The FAULT output configuration
is normally energised and non-latching. This is the standard output configuration and it
cannot be changed. The FAULT circuit will be activated during the time-out function, a low
power or loss of power condition, and during a failed COPM check. During these
conditions the FAULT relay will de-energise and the analogue output signal will drop to
0 mA (2mA for COPM Faults) for the duration of the FAULT.
FAULT relay contact rating is 1A @ 30VRMS/42.2VPK Resistive.
COMM
Description: This is the common connection of the WARN, ALARM and FAULT relay
contacts.
