Introduction

OVERVIEW
16 Channel I/OPanel Module (S772)
The 16 Channel I/O Interface enhances the versatility of the alarm system by providing additional input and
output capabilities to the FireNET L@titude Fire Alarm ControlPanel. Inputs and outputs can be selected for up
to 16 individual channels. All inputs and outputs are configured in the same way as devices connected to
addressable loops of the panel. The 16 Channel I/O Interface can be configured to contribute or act upon cause
and effect logic.
Use Case Examples
The 16 Channel I/OInterface can be used to interface the L@titude panel to a NAC extender or Voice
Evacuation system, by providing
linputs to the L@titude panel for dry contact closures such as General Trouble, AC Power Trouble, or Battery Trouble
from these devices.
loutputs from the panel to control various NAC or Voice Evacuation outputs.
The 16 Channel I/OInterface can be used to interface the L@titude panel to a secondary panel or releasing
panel, by providing

Installation

Install this product in accordance with NFPA 72, the National Electrical Code, and all local codes.
WARNING! The module must be installed by personnel familiar with electronic components. Electronic
components within the module are vulnerable to damage from electrostatic discharge. Ground straps must be worn by
installers before handling to prevent electrostatic discharge damage.
Before You Begin
The following item is not included with the FireNET L@titude Fire Alarm ControlPanel, but is required for the
installation:
lA Ground Strap is required for handling circuit boards.
Setting the Address
Panel modules should use addresses 1-8. Each panel module of the FireNET L@titude Fire Alarm
ControlPanel must contain a unique setting before being connected to the Main Back Board. The binary setting
of the DIP switch sets the specific address for the panel module. The numeric order of the address setting
between modules does not impact operation, but each panel module must be assigned a separate / unique
address.
The black portion of the DIP switch identifies the switch actuator.
Placement
To install modules on the FireNET L@titude Fire Alarm ControlPanel:

Wiring
Inputs
These inputs are intended for use as control signals from other life safety equipment. Inputs of this device are not
supervised, and cannot be used as initiating circuits for life safety applications within a UL listed system.
Inputs on the 16 Channel I/O Interface are intended to be activated by connecting the input to a 0V terminal
through volt-free contacts. Contacts must be suitably rated to handle 24VDC. The switch-current caused by
contact closure is limited to a maximum of 3mA.

Installation

Outputs
These outputs are intended for use as control signals to other life safety equipment. Outputs of this device are not
supervised, and must not be connected to notification and/or releasing type appliances in a UL listed system.
IMPORTANT! When powering the 16 Channel I/O Panel Module from one of the AUX24V outputs of the panel, it is
recommended that external 100mA fuses be inserted at the AUX24V+terminal. Failure to use a fuse will prevent the
protection of the output and void the product warranty.
WARNING! Incorrectly connected diodes will damage 16 Channel I/O Panel Module outputs. Installers must
connect the cathode-band of the suppression diode to the positive terminal of the relay coil as shown to provide
protection.
Each output is rated up to 100mA, therefore a
100mA fuse must be used to provide protection.
Multiple channels may be protected with a single
100mA fuse if their combined currents will not
exceed 100mA.
This example shows 2 LEDs protected by a single
fuse. The combined current draw of these LEDs
will not exceed the 100mA fuse rating.
The relay is protected by a separate fuse because
its current draw would exceed 100mA if combined
with the LEDs.
Outputs are intended to be connected to a 24VDC load. Theother side of this load should be connected to a 24V
power source, such as the panel's AUX24V+ terminal.

Installation

lAll output terminals are internally pulled-up to the panel's 24V power source through high impedance.
lWhen active, output terminals are pulled down to the panel's 0V through low impedance.
lOutputs should never be pulled below 0V or above 24 VDC by external circuitry.
lIndividual channel loads must not exceed 100 mA. Output terminals are not protected from overcurrent conditions.
Exceeding their current rating can cause permanent damage to the panel module.
lChannels 1-8 must be limited to 400 mA combined.
lChannels 9-16 must be limited to 400 mA combined.
Refer to the FireNET L@titude Fire Alarm ControlPanel Installation Manual (MAN-1431HA) for detailed
information on connecting field wiring and wiring terminal locations.
Restrictions
Inputs are intended for use as control signals from other life safety equipment. Inputs of this device are not
supervised, and therefore cannot be used directly as initiating circuits for life safety applications within a UL listed
system. Outputs are intended for use as control signals to other life safety equipment. Outputs of this device are
not supervised, and cannot be directly connected to notification or releasing-type appliances in a UL listed
system.
In a ULlisted system, the 16 Channel I/O Panel Module:
lmust be wired in conduit (or equivalently protected against mechanical injury) and within 20 feet of equipment being
interfaced.
lmust not be used to control the release of extinguishants.

LED 1 Heartbeat Red Flashes every 2 seconds when theboard is operating.
LED 2 Rx Comms Green Flashes every 2 - 3 seconds when the module is receiving data from the
panel.
LED 3 Tx Comms Green Flashes every 2 - 3 seconds when the module is transmitting data to the
panel.
LED 4 Trouble Yellow Flashes every 2 seconds when one or more outputs have a trouble
condition.
LED 5 Input Active LED Red Flashes every 2 seconds when one or more inputs are active.
LED 6 Output Active LED Red Flashes every 2 seconds when one or more outputs are active (low).

Channel Properties
For channels set as Outputs
1. Select the desired Output Options. This selection will activate the circuit when the selected event(s) occur.
2. Set whether the output will be Silenceable. Each channel is configurable in reaction to the Alarm Silence button on
the front panel. Check the box if the channel should return to normal standby when Alarm Silence is active. If this
box is checked, the Second Delay field is displayed.
3. Each output circuit is normally floating, but is pulled-low (to 0V) when activated. Selecting Output Invert will set the
circuit to normally be pulled-low (to 0V), but become floating when activated.
4. Ignore Global Delays. This setting controls the delay of the activation of the output. If unchecked, it will activate
based on the Global Delay settings in the Panel Settings. If checked, it will activate based on the settings in the
Hochiki America Corporation

Version 1.00 |March 2021 |MAN-1420HA

Configuration

First Delay and Second Delay fields. Second Delay is only visible if the output is silenceable. For ULcompliance,
both delays must be set to 0.
NOTE If checked,
- the initial activation of the output will be delayed based on the settings in the First Delay field.
- if the output is silenceable, subsequent re-sounding of the output will be delayed based on the settings in the Second
Delay field.
5. Enter a Duration to select how long an output will be active. If set to 0, it will remain active until the system is reset.
For ULcompliance, this field must be set to 0.
6. Set the Location Text, up to 80 characters.
7. Use the Map to Zone field to set the zone number for the circuit. Allowable values are 0-2000.

Configuration

For channels set as Inputs
1. Choose an Input Action.
2. Input Action Message is automatically set based on the selected Input Action. If desired, a custom Input Action
Message can be entered.
3. Check the Output Delay Bypass box if activation of this circuit should immediately activate its associated outputs,
even if those outputs have configured delays. For ULcompliance, this field must be checked.
4. Set the Input Delay in seconds, up to 180 seconds. Input activation will prevent the panel's response for specified
time period when the input is activated. No activation will occur if the input state is reset to normal before time period
expires. For ULcompliance, this field must be set to 0.
