Elevator Ultra-Thin Fire Box with Fireman’s Switch (Bottomless Box): Emergency Fire Core from Nanjing Zhuye Elevatorparts

The Elevator Ultra-Thin Fire Box with Fireman’s Switch (Bottomless Box) is a critical emergency fire protection component for elevator systems, specifically designed to house and protect the fireman’s switch—enabling firefighters to quickly activate the elevator’s fire service mode during emergencies. As the “key gateway” of the elevator’s fire protection system, this ultra-thin bottomless box is installed in fire-safe areas (e.g., elevator lobbies, fire control rooms) to ensure the fireman’s switch is easily accessible yet protected from misoperation or damage. The Elevator Ultra-Thin Fire Box with Fireman’s Switch (Bottomless Box), exclusively supplied by Nanjing Zhuye Elevatorparts (a professional and trusted distributor of high-quality elevator components), fully complies with international fire safety standards (EN 81-76, GB 7588) and is perfectly compatible with mainstream elevator fireman’s switch specifications. Featuring an ultra-thin design (thickness ≤ 30mm), high flame-retardant performance, and easy installation, this fire box provides reliable fire protection guarantees for elevators in residential buildings, commercial complexes, office towers, hospitals, and other buildings worldwide.
Nanjing Zhuye Elevatorparts adheres to the core philosophy of “safety first, quality-oriented” and implements strict quality control over the elevator ultra-thin fire box. Each fire box undergoes a multi-stage pre-delivery inspection, including flame-retardant performance testing, impact resistance verification, corrosion resistance detection, and dimension accuracy trials. The product adopts high-strength flame-retardant ABS material (V0 flame-retardant grade), an ultra-thin integrated structure, and a secure lockable cover: the flame-retardant material effectively resists open flames and heat spread, meeting the 90-minute fire resistance requirement; the ultra-thin design (thickness ≤ 30mm) saves installation space and adapts to narrow wall spaces; the lockable cover prevents non-emergency misoperation while allowing firefighters to quickly open it with a dedicated key. Its bottomless design facilitates wiring and integration with the wall, and the standardized interface ensures seamless matching with the fireman’s switch and elevator control system.

Step-by-Step Usage Guide for Elevator Ultra-Thin Fire Box with Fireman’s Switch (Bottomless Box)

To ensure the reliable operation of the elevator’s fire protection system and extend the service life of the ultra-thin fire box, follow the professional guidelines provided by Nanjing Zhuye Elevatorparts for installation, operation, and maintenance:

1. Professional Installation & Commissioning

Installation must be performed by certified technicians familiar with elevator fire systems. Prior to installation, confirm the compatibility of the fire box with the target elevator’s fireman’s switch model using the detailed compatibility manual provided by Nanjing Zhuye Elevatorparts. The steps are as follows:
  • Safety Preparation: Cut off the elevator’s main power supply and the power supply of the fire control system, and hang a “Maintenance in Progress—Do Not Power On” sign at the power switch. Select the installation position according to fire safety specifications (usually 1.5–1.8m above the ground, in a well-lit, unobstructed area of the elevator lobby). Clean the installation wall surface to remove dust, oil stains, and debris.
  • Box Installation: Since it is a bottomless box, first route the fireman’s switch wires through the wall opening to the installation position. Align the ultra-thin fire box with the wall opening and fix it firmly to the wall using expansion screws provided by Nanjing Zhuye Elevatorparts. Ensure the box is installed horizontally with no tilt, and the cover can be opened and closed smoothly. The gap between the box and the wall should be ≤ 2mm to avoid dust accumulation.
  • Switch Assembly & Wiring: Install the fireman’s switch into the ultra-thin fire box and fix it with dedicated screws. Connect the switch’s wiring to the elevator control system and fire alarm system according to the wiring diagram and Nanjing Zhuye’s technical guidance. Ensure the wiring is tight, correctly polarity, and wrapped with fire-resistant tape. After wiring, install the lockable cover and test the lock’s functionality (ensure it can be opened smoothly with the dedicated key).
  • Post-Installation Testing: Restore the power supply of the elevator and fire control system. Conduct comprehensive functional tests: use the dedicated key to open the fire box cover, activate the fireman’s switch, and confirm the elevator correctly enters fire service mode (e.g., returns to the designated floor, keeps doors open). Test the cover’s closing and locking performance to ensure it is tightly sealed. If the switch fails to activate the fire mode or the box is loose, recheck the installation and wiring immediately.

2. Daily Operation & Routine Inspection

Regular inspections are crucial to early detection of fire box faults and ensuring the elevator’s fire protection function is effective. Maintenance personnel should incorporate the following checks into their daily patrols:
  • Daily Visual Inspection: Check the external state of the ultra-thin fire box. Ensure the flame-retardant shell is free of cracks, deformation, or damage; the lockable cover is intact and tightly locked; the “Fireman’s Switch” label (attached to the box surface) is clear and legible. Wipe the box surface with a dry, lint-free cloth to remove dust and stains.
  • Weekly Functional Check: Use the dedicated key to open the fire box cover (record the inspection time) and check the fireman’s switch for looseness or damage. Test the switch’s button response (ensure it is sensitive and can be reset automatically). After inspection, close and lock the cover tightly to prevent dust or water intrusion.
  • Monthly Parameter Monitoring: Check the installation screws of the fire box for looseness and retighten them if necessary. Inspect the wiring through the bottomless opening (without disassembling the box) to ensure no aging, wear, or loose connections. For boxes installed in humid areas, check the shell for corrosion and apply anti-corrosion agent if needed.

3. Regular Maintenance Schedule

Systematic maintenance can effectively extend the service life of the elevator ultra-thin fire box. Follow Nanjing Zhuye Elevatorparts’ recommended maintenance plan:
  • Quarterly Maintenance: Disconnect the power supply of the fire control system, open the fire box cover with the dedicated key, and thoroughly clean the box interior and the fireman’s switch surface with a dry cloth. Apply a small amount of lubricant to the lock core to ensure smooth opening and closing. Check the flame-retardant performance of the shell (no discoloration or deformation indicating flame-retardant failure).
  • Semi-Annual Performance Test: Conduct a comprehensive performance test, including flame-retardant integrity, lock functionality, and switch compatibility. Simulate a fire scenario to verify that the fire box does not deform or burn under high-temperature conditions (short-term test using a temperature tester). For boxes in harsh environments (high humidity, high dust, or frequent human contact), increase the test frequency and replace the lock core if it becomes stuck.
  • Annual Professional Overhaul: Arrange a professional inspection with Nanjing Zhuye Elevatorparts’ certified technical team. Disassemble the fire box (by professional personnel) to inspect the internal structure for aging or damage. Replace worn components (e.g., lock core, screws) with genuine parts. Conduct a full-range calibration of the fireman’s switch and fire box assembly to ensure they meet the original factory safety standards.

Recommended Replacement Cycle for Elevator Ultra-Thin Fire Box with Fireman’s Switch (Bottomless Box)

As a core fire protection component bearing long-term environmental erosion and potential impact, the elevator ultra-thin fire box has a specified service life. Timely replacement is critical to avoiding box failure, which may lead to inaccessibility of the fireman’s switch during emergencies, affecting fire rescue efficiency and endangering lives and property.

1. Standard Replacement Cycle

Under normal operating conditions (indoor environment, temperature -10–60℃, humidity 10%–90%, no severe impact or corrosion), the recommended replacement cycle for the elevator ultra-thin fire box (bottomless) is 8–10 years. This cycle is determined based on Nanjing Zhuye Elevatorparts’ long-term field data, including material aging tests, flame-retardant performance degradation analysis, and actual operation feedback.

2. Adjustments for Special Scenarios

  • Harsh Environments: For elevators in high-humidity coastal areas (salt spray corrosion), high-dust construction sites, or buildings with frequent temperature fluctuations (e.g., unheated warehouses), the replacement cycle should be shortened to 5–7 years. Harsh conditions accelerate the aging of the flame-retardant material, corrosion of the shell, and failure of the lock core, significantly reducing the fire box’s reliability.
  • Low-Frequency Use & Protected Scenarios: For elevators in well-maintained buildings (e.g., high-end office towers, luxury residential buildings) with clean environments and low foot traffic, the replacement cycle can be appropriately extended to 10–12 years—only if Nanjing Zhuye’s professional inspection confirms that the flame-retardant performance, lock functionality, and structural integrity are all intact.

3. Immediate Replacement Conditions

Replace the ultra-thin fire box immediately if any of the following issues occur, regardless of service life:
  • The shell is severely cracked, deformed, or burned, failing to protect the fireman’s switch; the flame-retardant performance is compromised (confirmed by professional testing).
  • The lock core is stuck or damaged, making it impossible to open the cover quickly during emergencies; the cover cannot be tightly locked, leading to dust or water intrusion.
  • The installation structure is loose or damaged, posing potential safety hazards of the box falling; the gap between the box and the wall exceeds 5mm, affecting protection performance.
  • The box cannot be compatible with the fireman’s switch after elevator maintenance or upgrade, and modification is not feasible.
In conclusion, the Elevator Ultra-Thin Fire Box with Fireman’s Switch (Bottomless Box) supplied by Nanjing Zhuye Elevatorparts is a high-quality, reliable fire protection component tailored for elevator systems.
