Overview:

Altronix FireSwitch108 is a cost-effective managed NAC Power Extender. It interfaces with 12 or 24VDC Fire Alarm Control Panels (FACP) to provide Notification Appliance Circuit expansion support, for additional horns/ strobes to allow ADA compliance. It also provides auxiliary power to support system accessories. It delivers electronically regulated and filtered 24VDC power to Class B or Class A NAC loop circuits. The alarm current can be divided between the eight (8) outputs for powering NAC devices. Outputs are rated at 2.5A max. and can be independently programmed for Steady, Temporal Code 3 or Strobe Synchronization. All outputs may be programmed for Input to Output Follower Mode (output will follow the input. i.e. March Time Input, March Time Output). In non-alarm conditions, independent loop supervision for Class A and/or Class B FACP NAC circuits is provided. In the event of loop trouble, the FACP will be notified via the steered input (Input 1 or Input 2). In addition, there are common trouble output terminals [NC, C, NO] that are used to indicate general loop/ system trouble. Two (2) FACP signaling outputs can be employed and directed to control supervision and power delivery to any combination of the eight (8) outputs. It provides a programmable LCD display interface, plus an ethernet port interface for remote programmability and monitoring.

Installation Instructions:

Wiring methods shall be in accordance with the National Electrical Code NFPA 70/NFPA 72/ANSI/Canadian Electrical Code/CAN/ULC-S524/ULC-S527/ULC-S537, Signaling Code, and with all local codes and authorities having jurisdiction.
THE PRODUCT IS INTENDED FOR INDOOR DRY USE ONLY.
Carefully review:

1.  Mount the unit in the desired location. Mark and predrill holes in the wall to line up with the top two keyholes in the enclosure. Install two upper fasteners and screws in the wall with the screw heads protruding. Place the enclosure’s upper keyholes over the two upper screws; level and secure. Mark the position of the lower two holes. Remove the enclosure. Drill the lower holes and install the two fasteners. Place the enclosure’s upper keyholes over the two upper screws. Install the two lower screws and make sure to tighten all screws (Enclosure Dimensions, pg. 24). Secure enclosure to earth ground (Fig. 1, pg. 5). Small terminal block wire gauges range from 16 AWG to 22 AWG, all others range from 12 to 22 AWG.

2. Connect the line [L] and neutral [N] terminals to a separate unswitched 20A protected branch circuit (120VAC, 60Hz) dedicated to the Fire Alarm System. Connect ground to the ground lug (Fig. 1, pg. 5). Use 12 AWG wire.

3. Connect two (2) 12VDC batteries wired in series to terminals marked [– BAT +] (Fig. 2, pg. 6).
   Note: If batteries being used in your installation do not fit into the FireSwitch unit, it is required to install a separate enclosure UL Listed for the appropriate application. A separate battery enclosure is required to have 50 cubic inches of additional open space. All wiring methods shall be in accordance with the National Electrical Code NFPA 70/NFPA 72/ANSI/Canadian Electrical Code/CAN/ULC-S524/ULC-S527/ULC-S537 and with all local codes and authorities having jurisdiction. Battery circuits are not Power- Limited. Provide 0.25” spacing from Power-Limited circuits and use separate knockout. If an additional battery enclosure is required, it must be UL Listed for the application and mounted within 5’ of the FireSwitch enclosure in the same room, a minimum of 12 AWG wires in appropriate conduit is required for connection. When using conduit, make sure it is installed in a matter where it can not turn.

4. To trigger NAC outputs via the FACP signaling circuit(s) (polarity reversed) set INP1 and INP2 DIP switches to the OFF position. To trigger NAC outputs via the FACP dry relay contact (normally closed NC) set INP1and INP2 DIP switches to the ON position (Fig. 2a, pg. 6).

5. Determine the functionality of outputs [OUT1] through [OUT8]. Outputs can be programmed as Class “A” NACs, Class “B” NACs, and Aux. power output(s) with battery backup or Aux. power output(s) without battery backup. Note: Not all devices can use the sync feature. Be sure to check Appendix A to ensure the device you have chosen will work with this feature. Note: When programming outputs for Aux. power it will not be affected by the FACP trigger input. (Refer to Fig. 4, pg. 9 for Wiring, for Programming refers to pg. 10).

6. Determine which NAC input will trigger the desired NAC output(s).

7. Select output options (for Programming refer to pgs. 9-11). Note: The 2-wire horn/strobe sync mode will only synchronize horns, horns/strobes, and strobes with synchronization capability. For Class, B outputs connect EOL (AL-EOL10) to the last device in each NAC Loop. For applications in Canada use EOL10K-C end-of-line resistors (to be ordered separately). Form the leads to fit the terminals. Bend radius can not exceed 0.125”. Do not bend closer than 0.25” to the body of the resistor.

8. Connect desired 24VDC devices to regulated Aux. power output terminals marked [+ AUX – ] (Fig. 2, pg. 6). Output is Power-Limited. 0.25” spacing from Non-Power-Limited wiring must be provided. Use separate knockout.

9. Connect Digital Communicator or Local Annunciator to Common Trouble Output terminals marked [NC, NO, C]. Connection to triggering devices must be made within 20 ft. of distance and using conduit for wiring (Fig. 2, pg. 6).

10. Connect appropriate signaling notification devices to terminals marked [AC FAIL & BAT FAIL] supervisory relay outputs (Fig. 2, pg. 6).

11. Program FireSwitch utilizing an on-board programming switch or via ethernet port (for Programming refer to pgs. 9-11). When using an ethernet port, the cable has to terminate within the same building.

12.   WARNING: emergency control or nonfire equipment cannot be connected to same circuitry as fire alarm equipment.

FireSwitch Applications:

1. General Information:
Altronix FireSwitch units are very versatile devices. They can be used with or without specific synchronization modules provided by some manufacturers. Multiple units can be synchronized by using either the built-in sync mode or an external synchronization module. Please note that only notification appliances with synchronization capabilities can be synchronized. Units can operate with either one (1) or two (2) outputs from the FACP.
2. Class A and Class B Connections:
Units can be used with the outputs configured for:

• Four (4) Class A (Fig. 6).
• Up to eight (8) Class B.
• Combination of Class A and Class B outputs (Fig. 7).

Please make sure corresponding outputs are programmed appropriately.

CO and Fire Alarm Applications Requirements:
The FireSwitch108 shall be configured for all NAC Outputs to indicate one of the following types of Alarms and Events:

1. All NAC Outputs configured to indicate only Fire Alarms
2. All NAC Outputs configured to indicate only CO Alarms
3. All NAC Outputs are configured to indicate both CO Alarms and Fire Alarms.

If Item 1 is employed – Only Fire Alarms to be indicated, then the Trouble Relay connection to the FACP shall be Programmed to indicate “FIRE Trouble”at the FACP Display.
If Item 2 is employed – Only CO Alarms to be indicated, then the Trouble Relay connection to the FACP shall be Programmed to indicate “CO Trouble” at the FACP Display.
If Item 3 is employed – Both CO Alarms and Fire Alarms to be indicated, then the Trouble Relay connection to the FACP shall be Programmed to indicate “CO and Fire Trouble” at the FACP Display.

3. Combination CO and Fire Alarm Connections:
To comply with requirements of applicable UL and NFPA standards Fire Systems (UL 864), CAN/ ULC-S527-99 Control units for Fire Alarm Systems, NFPA 72, and NFPA 720 audible and visual notification appliances have to be used on different circuits. Systems have to be monitored by a supervising station and emergency response provided in accordance with NFPA 720.
For CO Alarms, the system must be monitored by a supervising station with emergency response.
CO combination mode settings are not accessible through the IP interface. In CO alarm mode the unit will indicate CO alarm which will be superseded by fire alarm if the fire alarm is initiated. In order for CO alarm mode to operate, horns and strobes have to be wired separately. The outputs for strobes should be programmed for 1e mode. The outputs for horns should be programmed for 2e mode. FACP has to initiate output 2 only during CO alarm and Output 1 and Output 2 during fire alarm conditions. To silence the horns during a fire alarm condition Output 2 has to be turned off, but Output 1 has to stay on. During CO alarm (Input 2 initiated only) horns will generate CO alert sequence (Temporal 4 pattern) and strobes will flash every second. During fire alarm conditions (Input 1 only or Inputs 1 and 2) strobes will flash and horns will generate a Temporal3 pattern unless silenced.
The FACP to INP1, and INP2 wiring connections are to be in a conduit within 20 ft.

System Sensor – Horns must be set for a coded output.

4. Non-Synchronizable NAC Appliances:
When using NAC appliances not designed to support synchronization features, it is recommended to use separate output circuits for audible notification appliances (horns) and visual notification appliances (strobes).
Program the FireSwitch to follow Input 1 [IN1] and for audible notification appliances to follow Input 2 [IN2]. This will allow, when using two (2) outputs from the FACP, to support the silencing of audible notification appliances. When using only one (1) FACP output, program to follow Input 1 [IN1]. The unit outputs can each be set for the desired NAC drive signal, such as Code 3 (Output Programming Selection Table, pg. 9). Non-synchronizable Audible Appliances will follow the sequence when the feature is selected.

5. Using Multiple NAC Power Extenders from an FACP:
FireSwitch is designed to follow (replicate) the coded sequence, generated by a manufacturer’s sync module. Up to eleven (11), FireSwitch108 units can be synchronized when interconnected with a host FACP. Connect the output of the FACP module to Input 1 and Input 2 Terminate the input circuit with the EOL (FACP), connecting it to terminals marked [RET +] and [RET –], or continue the input circuit, connecting to terminals marked [RET +] and [RET –] to [INP +] and [INP –] of the next unit when multiple units need to be triggered.

In case FACP does not have any synchronization capabilities and the sync mode is not used, the notification appliance synchronization will not be provided.

CAUTION: Do not connect any notification appliances on the control circuit interconnecting FACP outputs (sync module outputs) and inputs of NAC Power Extenders. Applications that do not employ a synchronization module or FACP with synchronization protocol will not provide NAC synchronization between NAC Power Extenders.

6. Synchronizing NAC Power Extender Using Built-In Sync Protocol:
FireSwitch units include built-in protocols to support Amseco/Potter, Gentex®, System Sensor® or CooperWheelock® two-wire synchronizable devices, therefore an external sync module is not required (OutputProgramming Selection Table, pg. 9). In these modes, Input 1 is always used to activate visual notification appliances (strobes), and Input 2 is used to activate and silence audible notification appliances (strobes) (Table, pg.9).
Note: Input 1 has to be activated in all the configurations.

7. Synchronizing multiple NAC Power Extender units (up to twelve):
Method 1 allows up to twelve (12) units to be synchronized (Fig. 10, pg. 17).
Method 2 allows up to four (4) units to be synchronized (Fig. 11, pg. 18).

When connecting, keep wires on different sides of the screw terminals in order to maintain loop integrity supervision.
DO NOT LOOP CONTINUOUS WIRE AROUND THE SCREW.

For this application set Dip Switches for INP2 to the “ON” position on all units, except the one triggered by FACP

8. Using a Single FACP Output:
When only one FACP output is available, you may connect both Input1 and Input2 to it.
Wire [RET1+] and [RET1–] to [INP2+] and [INP2–].
Both visual and audible notification appliances will be activated simultaneously (Fig. 13, pg. 20).

DIP Switches 1-4 Settings:
Dry contact INP1 configuration set SW1 and SW3 to the ON position.
Dry contact INP2 configuration set SW2 and SW4 to the ON position.
When connecting INP1 to the sync output of the FireSwitch unit for synchronization purposes set SW1 to the ON position and SW3 to the OFF position. For INP2 to the sync output of the FireSwitch unit for synchronization purposes set SW2 to the ON position and SW4 to the OFF position.

| SW1| SW2| SW3| SW4
---|---|---|---|---
INP1 – Dry NC| ON| –| ON| –
INP2 – Dry NC| –| ON| –| ON
INP1 – Sync| ON| –| OFF| –
INP2 – Sync| –| ON| –| OFF
