Product Summary
The Four Zone Input/Two Output Expansion SnapCard™ combines the capabilities of the Eight Zone
Input and Four Output Expansion SnapCards. It
allows for Concord™ panel, Advent™ panel, and
Superbus™ 80 Zone Input/16 Output Module expansion.
The card includes the following:
■ One 12V two-wire smoke detector loop that pro-
vides power (100mA) to Style B (Class B) smoke
detectors.
■ Three supervisedUL Fir e rated har dwire loops (2k
ohm EOL resistors required) that can be used for
any hardwire device including:
4-wire smoke detectors, fire pulls, water flow
detector switches, gate valve switches, control
valve supervisory switches, butterfly valve
switches, rate-of-rise detectors, carbon monoxide
gas detectors, assorted other gas detectors and
standard burglar devices.
■ False alarm prevention.
When the panel receives an alarm from a smoke
detector, the panel briefly interrupts power to the
smoke loop. Smoke detectors reset and recheck
the alarm.
■ Two “Form C” contact relays. The relays are con-
trolled by a touchpad or a combination of states
and events in the system.
On Advent™ panels, and Superbus™ 80 Zone Input/
16 Output Modules, this card may be installed into the
primary or secondary expansion slot and in combination with other cards.
Devices may be programmed to perform in various
ways. You can use the touchpad to turn on lights and
open drapes or a garage door. You can program the
system to turn on a closed-circuit-TV (CCTV) camera
during a burglary a larm, turn exit light ing on duri ng a
fire alarm or activate backup cellular phones or longrange radios if primary communications are inoperable.
Installation Guidelines
■ Install a 2k ohm EOL resistor at the end devi ce on
each supervised two-wire hardwire loop.
■ Install a po wer supervision module at the end
device on four-wire smoke loops.
■ Plug the expansion card into t he Concor d™ pa nel
expansion slot or either the primary or secondary
expansion slot of the Advent™ panel or SuperBus™ 80 Zone Input/16 Output Module.
■ Use 4-conductor , 22-ga uge or lar ger stranded w ire
from the terminals to the devices.
Tools Needed (optional)
■ Screwdriver
■ Four-conductor, 22-gauge or larger stranded
hookup wire
■ Thread rolling mounting screws (included)
■ 2K ohm end-of-line (EOL) resistors

To wire the card:
1. Disconnect panel power and backup battery.
2. Wire the smoke d etectors or other d evices. Table 2
describes how to wire various devices. Use terminals 11 and 12 for the two-wire 12V smoke detector loop. (Y ou can connect up to 20 two-wire
smoke detectors on this loop.)
3. Use EOL resistors as shown on any hardwire loops.
4. Reconnect the backup battery and panel AC power.
Programming
Input and output zones must be programmed to communicate with the panel and to function as desired.
For zone programming infor m at ion, r e fer to th e pan el
Installation Instructions.
Testing
Once installed, the card becomes an integral part of
the panel. We recommend that you test all input and
output zones after all programming is completed and
whenever a sensor or output related problem occurs.
Refer to the panel Installation Instructions and User’s
Manual for sensor/zone testing information.
Troubleshooting (all panels)
The following instructions help you diagnose and fix
card hardwire input and o utput problems.
Troubleshooting Hardwire Inputs
No inputs detected.
1. Check input device wiring and connections.
2. Check panel input programming.
One input is never detected.
1. Check input device wiring and connections.
2. Check panel input programming.
Wrong input is detected.
1. Check panel input programming.
2. Check input device wiring and connections.
Sensor Trouble is indicated.
1. Check that the 2.0K ohm end-of-line resistor is correctly installed in the zone loop circuit.
2. Check normally open (N/O) input circuit for a break in the wires.
3. Check normally closed (N/C) input circuit for a short in the wires.
4. Check input circuit for wires sho rted to ground.
5. Check that ZCOM (terminal 8) is used for input
zone common and not
GND (terminal 13).
Note:
While the sensor test is a valuable installation
and service tool, it only tests sen sor oper atio n fo r
the current conditions. You should perform a sensor test after any change in environment, equipment, or programming.
Troubleshooting Hardwire Outputs
No outputs activate:
1. Check panel/card programming.
2. Check output wiring and connections.
3. Check panel/card power supplies.
4. If used, check the optional external supply powering the output devices.
One output never activa tes :
1. Check panel/card programming for that output.
2. Check output wiring and connections.
3. Check that the output programmed trigger event actually occurs.
4. An output relay may have failed or been overloaded. Reprogram to use a different (unused)
output or replace the card.
Wrong output activates:
1. Check panel output programming.
2. Check output device wiring and connections.
