COMMON CARD
Indicators
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
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
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.
Programming
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.
ZONE CARD
Indicators
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.
Alarm Disconnect
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
Low /High Current
Operation
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.
Odd Zone
Even Zone
Resistors to remove for low current operation. R1,R2,R3 R21,R22,R23
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.
Addressing
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.
Zone Programming
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.
