The ZNS common card module has one LED. When first powered it flashes the

version number of the firmware on the ZNS module. Thereafter it will flash

whenever it is responding with zone information to an INS-2 poll.

Default operation is a mode that allows alarms to be sensed and automatically routed

to the Signaling Circuits, if for some reason the ZNS controller fails.

Auxiliary power is available on the Common Card from terminals A+, A-. Resetable

smoke detector power is available from terminals S+, S-. This power is removed for

four seconds when the system is reset. Combined total current available from both

A+,A- and S+,S- is 0.5 amps.

The ZNS Common Card is enabled by accessing level 4 programming area of the

INS-2 main board. Press the F1 key until the LED above the F1 key is illuminated.

Output controller location C220 must also be enabled and cannot be used by any

other devices. This output controller location allows the ZNS common card to reset

the S+, S- output.

Each 2 zone module has two LED's per zone, one to indicate alarm and the other to

indicate trouble. The standard zone module has a red and yellow, the supervisory

zone has two yellow LED's.

Each zone of the 31016 2 zone card has a disconnect switch located next to the

LEDs. When this switch is activated, the zone will not report an Alarm, but it will

show that it is in Trouble

Each zone of the 31016 2 zone card can be programmed for two modes of operation,

low current and high current. The module is factory set as a high current zone. Low

current mode is selected by removing the following resistors.

Resistors to remove for low current operation.

The EOL resistor high current value is 4.7K ohms and the low current value is 15K

ohms.

NOTE: Low Current zones will not function with 2-wire Smoke Detectors, and

should be used with contact closure devices only.

The 31016 zone modules must be mounted from left to right. If a slot is empty the

system will not detect modules beyond the first open slot.

Each 31016 2 zone card has jumpers to distinguish between Class A or Class B

initiating circuits. There are also jumpers to program latching and non-latching

zones. All 31016 modules are factory set for Class B latching alarm operation. See

the chart below for programming options. Refer to drawing A-M1105 For resistor

locations.
