The Altronix AL602ULADA(J), AL802ULADA(J), AL1002ULADA(J) NAC Power Extenders and R1002ULADA Rack Mountable NAC Power Extender are versatile devices designed to extend Notification Appliance Circuit (NAC) power and provide synchronization capabilities for fire alarm systems. These units can be used with or without specific synchronization modules from various manufacturers, offering flexibility in system design. Multiple units can be synchronized using either a built-in sync mode or an external synchronization module. It's important to note that only notification appliances with synchronization capabilities can be synchronized. The units can operate with either one (1) or two (2) outputs from the Fire Alarm Control Panel (FACP).
Function Description:
These power extenders are primarily designed to provide additional power for NAC devices such as horns, strobes, and horn/strobes, extending the reach and capacity of the FACP's NAC outputs. They can be configured for Class A or Class B hookups, supporting up to four (4) Class B circuits or two (2) Class A circuits. The devices can also be configured to combine one (1) Class A and two (2) Class B circuits.
A key feature is their synchronization capability. They support built-in sync protocols for Amseco, Gentex®, System Sensor®, and Wheelock® two-wire synchronizable devices, eliminating the need for an external sync module in these cases. In these built-in sync modes, Input 1 is typically used to activate visual notification appliances (strobes), and Input 2 is used to activate and silence audible notification appliances (strobes). Input 1 must be activated in all configurations.
For non-synchronizable NAC appliances, it's recommended to use separate output circuits for audible (horns) and visual (strobes) devices. DIP switches can be set for visual appliances to follow Input 1 [IN1] and audible appliances to follow Input 2 [IN2] when using two FACP outputs, allowing for silencing of audible notification appliances. If only one FACP output is used, all DIP switches should be set to follow Input 1 [IN1]. The outputs can be programmed for various NAC drive signals, such as Code 3 or march time sequence.
When using multiple NAC Power Extenders from an FACP, the units are designed to follow (replicate) the coded sequence generated by a manufacturer's sync module. One or more units can be triggered by connecting the FACP module's output to Input 1 and Input 2. The input circuit can be terminated with an End-of-Line (EOL) resistor or connected to the next unit's inputs for cascading. If the FACP lacks synchronization capabilities and the sync mode is not used, notification appliance synchronization will not be provided.
Important Technical Specifications:
- Synchronization Protocols: Built-in support for Amseco, Gentex®, System Sensor®, and Wheelock® two-wire synchronizable devices.
- Input/Output Configuration:
- Up to four (4) Class B outputs.
- Two (2) Class A outputs.
- Combination of one (1) Class A and two (2) Class B outputs.
- Input Control: Outputs can be controlled by Input 1 or Input 2, determined by DIP Switch 4.
- Output Modes:
- Input to Output Follower Mode: Output follows the signal received from the corresponding input (e.g., FACP Sync module), maintaining synchronization.
- Temporal Code 3 Mode: Enables Temporal Code 3 signal generation output. Accepts steady or pulsing input.
- Steady Mode: Generates a steady output signal. Accepts steady or pulsing input.
- Supervision: Loop integrity supervision is maintained.
- Dry Contact Input Wiring: Features IN1+, IN1-, IN2+, IN2- terminals for dry contact inputs, along with RET1+, RET1-, RET2+, RET2- for returns. Also includes C "DRY1" NC and C "DRY2" NC for normally closed dry contacts, typically for addressable control module trigger outputs (Non-Supervised Class E).
Usage Features:
- Flexible Hookups: Supports various Class A and Class B configurations to meet different system requirements. For Class A, NAC Loop 1 starts on Output 1 and terminates on Output 3 (SW1 ON), and NAC Loop 2 starts on Output 2 and terminates on Output 4 (SW2 ON). For Class A/Class B combination, only one switch (SW1 or SW2) needs to be ON for Class A termination.
- Synchronization Options: Can utilize built-in sync protocols or external synchronization modules, providing adaptability for different FACP types and device manufacturers.
- Multiple Unit Triggering: Designed to allow multiple NAC Power Extenders to be triggered from a single FACP or sync module, expanding system capacity.
- Single FACP Output Use: If only one FACP output is available, both Input 1 and Input 2 can be connected to it, activating both visual and audible notification appliances simultaneously.
- DIP Switch Configuration: Easy configuration of output modes and input control via DIP switches. Each output (OUT1-OUT4) can be programmed independently.
- Compatibility: Designed to work with various manufacturers' synchronization protocols (Amseco, Gentex®, System Sensor®, Wheelock®).
Maintenance Features:
- Wiring Integrity: Instructions emphasize connecting wires on different sides of screws to maintain loop integrity supervision and advise against looping continuous wire around screws.
- Troubleshooting: The application guide provides clear diagrams for different hookup configurations, aiding in proper installation and potential troubleshooting.
- Documentation: The guide serves as a supplement to the respective Installation Guide, providing additional information for application and configuration.
Enclosure Dimensions:
- AL602ULADA, AL802ULADA, AL1002ULADA (BC400): 15.5" x 12" x 4.5" (393.7mm x 304.8mm x 114.3mm).
- AL602ULADAJ, AL802ULADAJ, AL1002ULADAJ (BC600): 18" x 14.5" x 4.5" (457.2mm x 368.3mm x 114.3mm).
- R1002ULADA (Rack Mountable): 3.25" x 19.0" x 26.5" (82.6mm x 482.6mm x 673.1mm), shown with Z Bracket attached.
Important Considerations:
- 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.
- For synchronization modes, the same synchronization mode must be selected for all outputs.
- Altronix is not responsible for typographical errors.
- Lifetime Warranty. Made in U.S.A.
