system
TT or TN system.
Order of 3
relay
D1 D2 and alarm.
Relays
Control circuit (relay)
isolation
Galvanic isolation.
Circuit operating
voltage
Either SELV* or LV** with common phase (230 V maximum
between the 2 circuits).
Relay breaking
capacity
240V AC 1A.
Usefulness of
indicator light (of
each circuit)
1) Lit when contact closed.
2) Used to indicate the current circuit programming.
Types of relays
Double-throw (SPDT) on circuit 3.
Normally open (SPNO) on circuits 1 and 2.
Outputs
Synchronisation
Depending on model, on DCF, MSF or GPS antenna.
Minute or half minute
parallel polarised
impulse distribution
1 output 24V 1A, configuration in minute, ½ minute or second
impulse or SR2-59 or TBT 24V power supply.
D1D2 distribution
One output (D1 D2 uses the relays of circuits 1 and 2).
AFNOR coded time
distribution
One output, standard NFS 87 500A (no programming is
necessary) (SELV).
