User Jumpers
There are eight user jumpers on the pc board. If the jumpers are changed, the effect is immediate. No reset
is required.
J1 and J2 work together to configure which pins in the serial port DB-9 connector are used for the RTS
(from SDACT) and CTS (to SDACT) hardware handshake control signals. These should be set
appropriately for the specific FACP being monitored. (See Serial Port Installation notes.) The handshake
control lines, and therefore J1 & J2, are not used for PC programming mode.
J3 if removed physically disconnects power from the audible device, thereby disabling all local audible
signals.
J4 if removed disables supervision of the FACP serial port (SDACT only). J4 should be set appropriately
for the specific FACP being monitored. (See Serial Port Installation notes.)
J5, J6, and J7 set the normal condition of the power monitor zones 5, 6, and 7 respectively. Jumper
installed sets the zone to normally open. Jumper removed sets the zone to normally closed. The factory
default is all zones normally open.
J8 configures the transmission delay for AC power failure events. The delay applies to activations of the
AC Fail zone (zone 5) and AC power failure serial data messages from the monitored FACP (SDACT
only). J8 installed provides for a 2 Hour Delay for both sources of AC power failure events. J8 removed
provides No Delay. Note that removing J8 sets no delay for the next occurrence of an AC power failure
event, and will not cancel a 2 hour delay already in progress. (Refer to Programming features table on
page 33).
