(“Panel Health”) is green when the NV9700 itself is functioning properly and red if the NV9700 is
malfunctioning.
Panel Rear
This is a view of the rear of the panel:
At the left end are two power supply connectors. The NV9700 uses one or two PS0001 power sup-
plies
— two for redundancy. The connectors are keyed 4-pin Molex connectors. It is not possible to
connect the power supplies incorrectly. The connectors are labeled PS1 and PS2. LEDs on the front
of the panel are also labeled PS1 and PS2 and indicate whether a (good) power supply is connected.
Controller Connectors
Next to the power supply connectors are two DE9 connectors. These connect to the NV9000 sys-
tem controllers. The protocol is RS-422.
See Controller Connections for detail.
Relay Outputs
In the middle is a DB25 connector that supports relay output. The connector is labeled ‘GPI Inter-
face’. (This is a bit of misnomer. The DB25 supports general-purpose outputs or GPOs.)
The connector presents 7 relay outputs:
• Three (health, active, alarm) for system controller 1.
• Three (health, active, alarm) for system controller 2.
• One (alarm) triggered when any alarm condition exists.
See Relay Connections for detail.
DIP Switches
At the far right is an exposed set of DIP switches. There are 4 switches. The up position means the
switch is closed; the down position means the switch is open.
Switch 1 (on the left) enables the buzzer, when the switch is up.
Switch 4 (on the right) enables a technician to install new firmware in the panel. This switch should
be down under normal operation (and up to allow the firmware installation).
Switches 2 and 3 are unused at present.
Connections
For it to be useful, you must connect the NV9700 to both system controllers. You have the option of
using any or all of the relays to control external circuitry.
