Using a Fail secure lock connected to a reader
If using a fail secure type lock, i.e. the lock is secure when the power is down. Mortise or fail
secure type locks will normally be terminated using NC1 and C1, the opposite state to a maglock.
If required the relay output can be inverted using software.
Connecting a Sounder to a spare output relay
Check your OEM sounder documentation for signal requirements. The S610S output relay
provides normally open or normally closed connection options.
Connecting a Sounder.
Remember that the PCB legend applies when the PCB is un-powered.
When the PCB is powered the relay states become inverted.
Invert relay output
The relay legend on an S610S PCB reflects the relay state when the reader is powered down. As
soon as the S610S reader receives 12v power, the relay states become inverted. Therefore NO
(Normally Open) becomes CLOSED allowing voltage to a connected maglock.
If using a fail secure type lock, i.e. the lock is secure when the power is down, the connections on
J12 should be physically moved to the normally open connections on the relay in preference to a
software configuration. However, the relay state can be inverted using the
Devices, Configuration,
Relay 0 normally open
. The same applies to Relay 1.
A DIU lock output cannot be inverted using software settings.
