Code Blue 40905 WM-180 SBL Strobe Light with Wall Mount
Overview
The Code Blue 40905 is a WM-180 SBL (Strobe with no control input) designed as an audible-visual notification device for security and emergency applications. Running on 24V DC power, this model delivers synchronized strobe output with sufficient intensity for indoor and outdoor visible-alarm signaling across commercial buildings, parking facilities, and industrial sites. The 40905 is built for wall and pole mounting, providing flexible deployment options where rapid visual alert dissemination is required.
Key Features
- 24V DC Power Supply: Operates on standard 24V DC, simplifying integration into existing security infrastructure where centralized power distribution is already in place. This voltage is common across access control, alarm panels, and IP-based systems, reducing the need for additional power conditioning.
- IP68 Environmental Rating: Fully sealed against dust and water immersion, meaning the 40905 tolerates spray, submersion, and harsh outdoor conditions without signal degradation. Critical for parking structure perimeters, loading dock entrances, and wet environments where dust or washdown is routine.
- Strobe Light Output: Synchronized flash output provides high-visibility alarm indication across large areas. Strobe frequency and intensity meet standard commercial audible-visual alarm design, ensuring occupants and visitors recognize alarm state in noisy or visually cluttered environments.
- Wall and Pole Mount Flexibility: Dual mounting options—wall-surface and pole-attachment hardware—allow installation at eye level (wall) or overhead (pole, pedestrian gateway, or perimeter fence line). This flexibility accommodates both interior corridor deployment and exterior zone coverage without requiring custom fabrication.
- No Control Input: The WM-180 SBL designation indicates this unit activates strobe output when powered; no external control logic is required. Simplifies wiring in applications where the alarm condition is driven directly by a panel alarm relay or 24V DC switched circuit, reducing programming overhead and failure points.
- Commercial-Grade Construction: Rated for continuous industrial and institutional use, the 40905 withstands temperature cycling, vibration, and salt-air environments typical of critical-infrastructure alarm applications.
Integration & Compatibility
The 40905 integrates into any 24V DC security system architecture—fire alarm panels, access control systems, emergency notification platforms, and standalone burglar alarm equipment. The strobe output is NFPA-compliant for audible-visual alarm applications, meaning it works within code-driven emergency signaling deployments across commercial tenancies. Connect the 24V DC source directly to the unit terminals; no additional relays or drivers are necessary for standard on-demand activation.
Pair the 40905 with existing Code Blue strobe or horn units to create redundant or zone-specific alarm indication. The wall and pole mounts integrate with standard security cabinet and perimeter-fence infrastructure without site-specific modification.
Frequently Asked Questions
Q: What is the strobe frequency of the 40905?
A: The 40905 operates at standard commercial strobe frequency (typically 1–2 Hz per NFPA standards). Exact frequency specifications are available from Code Blue technical documentation; consult the manufacturer if frequency tuning or synchronization with other strobe units is required.
Q: Can the 40905 be used indoors and outdoors?
A: Yes. The IP68 rating ensures the 40905 handles both indoor climate-controlled environments and outdoor exposure to rain, dust, and temperature swings. It is suitable for building entrances, parking structures, loading docks, and perimeter zones.
Q: Does the 40905 require a control relay or can it be wired directly to a 24V DC alarm panel?
A: The 40905 WM-180 SBL has no control input—it activates whenever 24V DC power is applied. Wire it directly to a 24V DC switched circuit on your alarm panel. No additional control module or relay logic is needed.
Q: What mounting hardware is included?
A: The 40905 is supplied with wall-mount and pole-mount brackets. Verify exact hardware contents in the shipping carton; additional fasteners (anchors, lag bolts) may be required depending on substrate material (concrete, wood, aluminum).
Q: Is the 40905 compatible with other Code Blue alarm units?
A: Yes. Multiple Code Blue strobe and horn units can be wired in parallel on the same 24V DC circuit for zone redundancy or building-wide coverage. Ensure your power supply capacity is sized to handle simultaneous activation of all units.
Q: What is the warranty?
A: Consult Code Blue or your supplier for warranty terms on the 40905. Manufacturer warranty is standard; confirm coverage for both labor and parts in your purchase agreement.
The Code Blue 40905 is a straightforward audible-visual alarm device—no fancy electronics, no control logic embedded. That simplicity is its strength in security architecture. When you need rapid, unmistakable visual notification across a large footprint (parking structure, warehouse exterior, perimeter fence line), the 40905's IP68 strobe output does exactly one thing and does it reliably. The 24V DC requirement keeps integration simple on any panel-fed alarm loop.
Technical Highlights:
- IP68 Rating: Full immersion and dust protection means the 40905 survives washing, salt spray, and temperature swings in outdoor deployments without connector corrosion or optical degradation. If you're installing this in a parking structure or coastal facility, the IP68 seal is non-negotiable.
- 24V DC Direct Activation: No control relay, no latching logic—power applied = strobe on. Wiring is a pair of terminals to your panel's 24V switched circuit. Reduces fault points and makes troubleshooting straightforward: if the alarm relay closes, the strobe fires.
- Wall and Pole Mount Dual Options: Wall mounting puts the strobe at eye level indoors; pole mounting elevates it for perimeter zones or large outdoor areas. Both are included, so you don't need to source secondary hardware or custom fabrication.
Deployment Considerations:
- Verify your 24V DC power supply capacity before wiring multiple 40905 units in parallel—simultaneous activation of three or four strobe units will draw significant current, and an undersized supply will sag voltage and reduce strobe intensity.
- The 'No Control' (SBL) designation means the 40905 cannot be remotely silenced or dimmed—it strobe when powered. If you need selectable activation or acknowledge-able alarm cycles, you'll need a control input variant or an external relay module.
The 40905 fits best in large-footprint security designs where rapid, non-negotiable visual alarm is the priority: multi-building campuses, perimeter zones, parking facilities, and industrial yards where a single strobe at a choke point (gate, entrance, dock) must alert occupants across a wide area. Pair it with a Code Blue horn for redundant audio coverage, and you've built a robust NFPA-compliant alarm notification system with minimal wiring and no software overhead.
