The Honeywell Gate Module is an advanced, field-installable accessory designed to enhance the capabilities and reliability of compatible Honeywell Fire Alarm Control Panels (FACPs). Its primary function is to provide a supervised, resettable output that controls a dedicated release path for a gate or door mechanism, often used in fire-fighter access routes or secured entry points that require automatic unlocking during an alarm event. The module ensures that the gate or door can be reliably released when the FACP detects a fire condition, significantly improving emergency response and evacuation procedures.

Product Parameters (Specifications)

Operating Voltage: Typically 24 VDC (sourced from the FACP's regulated power supply).
Standby Current: Low current draw, generally less than 1 mA.
Alarm Current: Varies, but usually a maximum of 50 mA during activation.
Output Type: Supervised, dry contact, form C relay output.
Contact Ratings: Usually rated for 2.0 A at 30 VDC or 0.5 A at 125 VAC (resistive).
Operating Temperature: $32^\circ\text{F}$ to $120^\circ\text{F}$ ( $0^\circ\text{C}$ to $49^\circ\text{C}$ ).
Relative Humidity: 10% to 93% non-condensing.
Wiring: Utilizes two pairs of supervised wires from the FACP's Signaling Line Circuit (SLC) or dedicated control circuit.
Mounting: Designed to mount in a standard 4-inch square electrical box or directly within the FACP enclosure (model dependent).

Product Advantages

The Honeywell Gate Module offers several key advantages for system integrity and safety:

Enhanced Safety: Provides reliable, automatic gate release during a fire event, ensuring clear access for emergency personnel and safe egress for occupants.
Supervised Operation: The module's output is constantly monitored by the FACP. This supervision ensures that any wiring fault (open or short circuit) on the control line is immediately reported, guaranteeing the system's operational readiness.
Easy Integration: Designed for seamless compatibility with a wide range of Honeywell FACPs, simplifying installation and programming.
Field Programmable: It can be easily configured through the FACP programming interface to meet specific application requirements, such as trigger conditions and activation delays.
Robust and Reliable: Built with high-quality components for long-term reliability and minimal maintenance, meeting stringent industry standards.

Important Precautions (Notes)

Installation: Must be installed in accordance with the National Fire Alarm Code (NFPA 72), local codes, and the instructions provided in the module's installation manual. Only qualified, authorized personnel should perform the installation and wiring.
Power Down: Always disconnect all power sources (AC mains and battery) to the Fire Alarm Control Panel before installing, wiring, or servicing the module.
Wiring: Ensure all wiring is the correct gauge and properly supervised, as specified in the panel and module documentation, to maintain system integrity.
Testing: The system must be thoroughly tested after installation to confirm that the gate release mechanism functions correctly under fire conditions and that all supervisory signals are operational.
Gate Mechanism Compatibility: Verify that the gate or door release mechanism (e.g., magnet lock, strike, or motor control) is compatible with the module's contact rating and operating voltage.

Product Applications

The Honeywell Gate Module is primarily used in applications where controlled, secured access must be overridden automatically in a fire emergency:

Gated Communities and Residences: Automatically opening vehicular or pedestrian security gates to allow fire department access.
Commercial and Industrial Facilities: Releasing security gates or roll-up doors surrounding a facility perimeter.
Secured Data Centers and Server Rooms: Controlling access to critical areas where immediate emergency access is mandatory.
Parking Garages: Releasing barrier gates at entry/exit points to facilitate rapid evacuation and emergency vehicle entry.
