Notification Appliances

Notification Appliances operate with the XT+ Extinguishant Control Panel in a special application or regulated mode. The panel supports the simultaneous operation of regulated and special application outputs between NACs. The XT+ Extinguishant Control Panel does not support the simultaneous operation of regulated and special application outputs on the same NAC channel. The panel supports special application outputs when operating: Gentex NAC devices System Sensor NAC devices Wheelock NAC devices Amseco NAC devices Synchronization modules are not required and should not be used on special application outputs. Synchronization NAC synchronization can be performed across all NAC channels of an individual panel. NAC synchronization cannot be performed across multiple panels. The XT+ Extinguishant Control Panel provides internal device synchronization between the outputs of NACs when operating NAC devices from Gentex, Amseco, System Sensor, or Wheelock without the use of an external synchronization module. External synchronization modules must not be used on the NAC outputs when operating in the synchronization mode. While most systems only use one device manufacturer, the XT+ panel can synchronize strobe devices from any two manufacturers simultaneously. Devices from different manufacturers cannot be combined on the same channel. Audible synchronization across manufacturers can only be accomplished between Gentex and System Sensor. The maximum number of strobes that can be synchronized for each brand is Amseco 2.37A / 88mA = 27 appliances Gentex 2.5A / 78mA = 32 appliances System Sensor 1.32A / 66mA = 20 appliances Wheelock 2.5A / 60mA = 41 appliances Configuring NAC Outputs Settings are provided in the panel GUI and Loop Explorer 2 for controlling the NAC outputs of the XT+ Extinguishant Control Panel. Selections are available in these utilities for providing outputs with synchronization or various forms of constant power. Settings are also provided to allow the Alarm Silence button to operate on the front panel in various modes. Review the settings described below to configure each NAC output for operation. Output Options General Alarm and Emergency are selected as default conditions. Alternative output options for this field include Auxiliary Output, Pre-Alarm Output, Supervisory Alarm, and Trouble. Do not select the General Alarm option if the NAC channel is to be controlled by cause-and-effect programming. Strobe Strobe Output is not selected for operation as a default condition. Selecting this field allows the user to define which synchronization protocol to be used. NAC AUX 24V DC When the Strobe option above is not selected, Off is selected as the default operating condition. Options for this output are continuous constant power, door holder, and resettable. Continuous constant power provides a voltage output comparable to AUX 24V. Door holder outputs lose power during fire alarm conditions and/or during AC power loss. Resettable causes power loss that lasts 4-5 seconds each time the panel is reset. Alarm Silence Each NAC is configurable in reaction to the Alarm Silence button on the front panel. Edit properties of the NAC channel in Loop Explorer 2. Select the box for Silencing if NAC silencing is required on this channel. If Internal Synchronization Protocols are in use, an option is also available to Silence the strobe. Failure to check the Strobe Silence box will cause horns to be silenced with continued operation of the strobe.   For more details, refer to NAC Output Specifications.

XT+ Network Module (S723)

The XT+ Network Module (S723) provides supervised, enhanced high-speed communication for networking up to a maximum of 127 fire control panels. The network provided by this module can support combinations of XT+ Extinguishant Control Panels and XT+ Vision Annunciators. XT+ Extinguishant Control Panels can receive events from other panels in the network. The Class X networking used in conjunction with the Network Module provides tolerance against open and short circuit trouble conditions.

The XT+ Network Module can be configured to operate in a "bridge mode", which enables the XT+ Extinguishant Control Panel to operate on a network with FireNET and FireNET Plus panels. The FireNET and FireNET Plus network can support up to 64 fire control panels, and has other limitations, such as more limited text-field lengths, zones, C&E relationships, etc.

For more information about the XT+ Network Module, refer to the XT+ Network Module Information Guide (MAN-1436).

Printer (S768)

The XT+ Printer is an optional feature for printing fire system events as they occur. The printer is located on the fascia, below the Zone LEDs (if present). It is a thermal printer and never requires replacement ink. Printing is performed on heat-sensitive paper rolls. A trouble message is reported when the paper runs out. The printer includes a front loading feature for replacing paper rolls. Refer to Equipment List for the part number and description of the paper roll replacement.

To load paper rolls in the printer: Lift the latch on the face of the printer to access the paper chamber. Load the paper in the paper chamber with the paper edge exiting from the top and with the shiny-side facing the top of the fire control panel. When the LED indicator is on and the printer is not in standby, you can press the << button on the face of the printer to test feed the paper.

When using a printer with a XT+ Extinguishant Control Panel fitted with a Plex-Door, the paper may adhere to the door because of the static generated when removing the protective film. To combat this, wipe the surface of the door with a slightly damp, soapy cloth before the first use.

Zone LED Module (S771)

The Zone LED module contains 48 LEDs and is connected to the LCD Main Processor Board of the XT+ Extinguishant Control Panel. A maximum of three Zone LED modules can be connected to provide the fascia with 144 Zone LED indicators. The following figure illustrates the component-side of the Zone LED Module:

The component side of the Zone LED module is visible when the cabinet door is open. Zone LED indicators are not present on the component-side of the Zone LED module. The opposite side of the image shown contains Zone LED indicators.

LED Number	Description

LED 50	Flashes red to identify functional status of the Zone LED module.

16 Channel I/O Interface Card (K1171)

The 16 Channel I/O Interface enhances the versatility of the alarm system by providing additional input and output capabilities to the XT+ Extinguishant 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 XT+ panel to a NAC extender or Voice Evacuation system, by providing

• inputs to the XT+ panel for dry contact closures such as General Trouble, AC Power Trouble, or Battery Trouble from these devices.
• outputs from the panel to control various NAC or Voice Evacuation outputs.

The 16 Channel I/O Interface can be used to interface the XT+ panel to a secondary panel or releasing panel, by providing

• inputs to the XT+ panel for dry contact closures such as Fire, Supervisory, and Trouble from these panels, and various stages of release from the releasing panel.
• outputs from the panel to activate NAC outputs on these panels.

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 Interface:

• must be housed in a separately-listed enclosure.
• must be located in the same room as the XT+ panel.
• must be located in the same room as the equipment being interfaced.
• must be wired in conduit (or equivalently protected against mechanical injury) and within 20 feet of equipment being interfaced.
• must not be used to control the release of extinguishants.

For more information about the 16 Channel I/O Interface, refer to the 16 Channel I/O Interface Information Guide (MAN-1438).

The XT+ Network Vision Annunciator is a display and control unit which duplicates the indications and primary controls of XT+ Extinguishant Control Panels connected to the same network. The Annunciator connects via the network interface, and any number of repeaters can be connected up to the maximum number of nodes allowed by the network.

XT+ Network Vision Annunciators can be configured to replicate fire control panel functionality or to operate as simple, display-only devices for applications where access to fire alarm controls are inappropriate. The Annunciator can be configured to display events from any combination of nodes on the network.

For more information about the XT+ Network Vision Annunciator, refer to the XT+ Network Vision Annunciator Information Guide (MAN-1434).

Media Gateway™ Panel Module (S788)

The Media Gateway™ is a communication panel module for the XT+ Extinguishant Control Panel. It provides connectivity to a remote monitoring center via Sur-Gard Fibro or dial-up. SIA is the recommended format for usage, but Contact ID is also supported. Transmission can be made through one or two telephone lines, and/or IP through Ethernet. Standard reporting codes have been pre-defined, although the user may customize these codes through the Loop Explorer 2 programming application.

For more information about the Media Gateway Panel Module, refer to the Media Gateway Panel Module Information Guide (MAN-1439).

8 Channel Relay Panel Module (S791)

The 8 Channel Relay Panel Modules have 8 voltage-free, unsupervised changeover relay contacts, each of which can be individually programmed.

All outputs are configurable in the same way as devices connected to the loops and all may be acted upon by cause and effect logic. These boards are typically used in applications which require more than the four standard relay outputs, such as signaling to other systems or plant control.

For more information about the 8 Channel Relay Panel Module, refer to the 8 Channel Relay Panel Module Information Guide (MAN-1440).

Batteries

Batteries are used as a secondary power source for the XT+ Extinguishant Control Panel, in the event that the primary power source (AC) fails.

Required standby battery capacity is dependent on the required standby period and load of the XT+ Extinguishant Control Panel system. Determine the current consumption of the fire alarm system for alarm and standby conditions. Use these maximum current values to determine the minimum required battery capacity of the fire alarm system.

Perform the installation only after calculations have been completed and a suitable battery capacity determined. Refer to Calculations or Loop Explorer 2 to determine the minimum required standby battery capacity of the system.

Standby Battery Type

The XT+ Extinguishant Control Panel is a 24 volt system designed to use Valve Regulated Lead Acid (VRLA) batteries as a secondary (backup) power source. VRLA batteries are not commonly available in 24V, so two 12V batteries are typically used, wired in series.
