What it actually does

This base is used to:

• Mount Siemens smoke / heat detector heads
• Provide electrical connection to fire alarm loop
• Maintain communication between detector and fire panel
• Enable quick detector replacement (plug-in design)
• Support addressable system communication

System Role (Simple)

Fire alarm control panel
→ addressable loop wiring
→ detector base (S24230-B150-A1)
→ detector head (smoke/heat sensor)
→ sends alarm signal back to panel

Key Features

• Plug-in detector mounting design
• Secure twist-lock detector head interface
• Loop-powered addressable communication
• Easy maintenance and detector replacement
• Reliable screw-terminal wiring connection
• Compatible with Siemens Cerberus / SIGMASYS systems

Typical Applications

• Commercial fire alarm systems
• Industrial safety monitoring
• Office buildings and warehouses
• Hospitals and public facilities
• Airports and transport infrastructure
• Siemens addressable fire detection networks

Advantages

• Fast detector installation and replacement
• Stable communication with fire alarm panel
• Reduces wiring complexity in ceiling devices
• Standardized Siemens fire system compatibility
• Long-term reliability in safety-critical systems

Important Notes

• Not PLC module ❌
• Not sensor itself ❌ (it is only the base)
• Not relay ❌
• It is a fire alarm detector mounting + interface base ✔

Precautions

• Must be used only with compatible Siemens detector heads
• Incorrect wiring may cause loop faults or device missing errors
• Dust or poor contact can cause intermittent alarm/trouble signals
• Must follow fire code installation spacing (NFPA / local standards)
• Installation should be done by certified fire alarm technicians
