Maple Armor FW2821 Addressable Supervised Input/Output Control Module (24VDC 2A Output)

Description

The Maple Armor FW2821 Addressable Input Output Module is a versatile, high-capacity life-safety interface engineered to control external notification circuits, damper actuators, and releasing solenoids while simultaneously supervising confirmation feedback contacts. Designed to operate seamlessly on the Signaling Line Circuit (SLC) of Maple Armor FW2105 and FW2107 panels, the Maple Armor FW2821 Addressable Input Output Module requires only a single address to deliver both output power switching and input status tracking. Fully compliant with UL 864 10th Edition and CAN/ULC-S527 standards, the Maple Armor FW2821 Addressable Input Output Module provides an uncompromising solution for controlling and monitoring critical building automation and fire protection equipment.

Supervised 2A Output Delivery & Real-Time Contact Feedback Verification

The primary engineering advantage of the Maple Armor FW2821 Addressable Input Output Module is its combined output switching and confirmation architecture. When triggered by the central panel, the module switches its 24VDC output circuit to activate bells, horns, strobes, door holders, or smoke dampers. Simultaneously, the built-in IDC channel monitors auxiliary dry contacts (such as microswitches or damper end switches) to verify that the commanded physical mechanical action has successfully completed.

To ensure high operational integrity, the Maple Armor FW2821 Addressable Input Output Module continuously supervises the external 24VDC power feeder as well as the output field lines. If an open line, short circuit, or auxiliary power loss occurs, a trouble report is instantly transmitted back to the central panel. Digital addressing via the FW2411 electronic programmer prevents addressing errors and speeds up commissioning across large multi-zone facilities.

• Combined Output & Confirmation: Powers external notification loads up to 2A while validating mechanical equipment status via feedback contacts.
• Full Line & Power Supervision: Actively monitors field wiring and auxiliary power lines against opens, shorts, and power failure.
• Single Address Economy: Provides dual I/O functionality under a single SLC address, optimizing total panel loop capacity.
• Clear Diagnostic Indication: Dual LEDs provide local visual feedback for normal polling, active output firing, and input confirmation.

Frequently Asked Questions (FAQ)

Q1: What is the primary function of the Maple Armor FW2821 Addressable Input Output Module?
A: The FW2821 provides a supervised 24VDC output circuit (up to 2A) to switch notification appliances, fire doors, or dampers, while simultaneously monitoring a dry-contact feedback input on the same single SLC address.

Q2: Does the module require an external 24VDC power supply?
A: Yes. While internal electronics and digital communications run off the SLC loop, an external supervised 24VDC power supply is required to power the connected output loads.

Q3: How does the feedback input circuit work on the FW2821?
A: The input circuit monitors a Class B dry contact (terminated with a 10 kΩ EOL resistor) to confirm that equipment—such as a motorized fire damper or fan starter—has physically operated.

Q4: How is the address assigned to this I/O module?
A: The digital address is programmed into the module’s non-volatile memory using the Maple Armor FW2411 handheld programmer prior to installation.

Q5: What mounting backboxes are compatible with the FW2821?
A: The module mounts flush to standard North American 4-inch square electrical junction boxes (minimum 2-1/8 inch depth) or surface mounts using Maple Armor FW800/FW801 plastic boxes.

Q6: Which fire alarm control panels support the FW2821?
A: It is fully compatible with Maple Armor Series 2 control panels, including the FW2105 standard multi-loop panel and the FW2107 dual-hazard agent releasing panel.
