Description
The Simplex 4098-9714 Addressable Smoke Detector bundled with the 4098-9789 Addressable Sensor Base represents a high-reliability life-safety kit engineered for advanced, early-stage fire containment across commercial and industrial infrastructure properties. Utilizing patented TrueAlarm analog sensing architecture, this precision photoelectric device digitally transmits environmental smoke density metrics back to a host fire alarm control unit every four seconds. Its low-profile, louvered structural engineering optimizes 360-degree smoke capture dynamics while ensuring a clean, flush integration against ceiling lines.

TrueAlarm Intelligent Drift Filtering & Louvered Capture Design
The core operating mechanism of the Simplex 4098-9714 Addressable Smoke Detector relies on a pulsed infrared LED light source paired with a high-accuracy silicon photodiode receiver. Unlike standard conventional smoke parameters that trip blindly when dust accumulates, TrueAlarm intelligent data processing establishes a continuously shifting reference point. The central panel uses software filtering to track background ambient drift, compensating for dust, pollen, humidity, and component aging over time. This keeps sensing sensitivity tightly calibrated to international safety thresholds, almost eliminating false alarms and unnecessary emergency service fees.
Additionally, the 4098-9789 base keeps system addresses bound permanently to its specific structural terminal position. The physical address is adjusted via internal DIP switches hidden securely beneath the detachable detector head. If a sensor head is removed for cleaning or building construction, maintenance teams can substitute a clean unit without reprograming the entire loop panel, saving substantial site commissioning time.
- 360-Degree Omnidirectional Smoke Entry: Louvered outer housing directs smoke paths into the sensing chamber cleanly from any approach angle while internal screens keep out insects.
- Adaptive Multi-Stage Timing Profiles: Enables facility engineers to program higher sensitivity settings (e.g., 0.2% obscuration) during quiet night hours and lower settings during busy day shifts.
- Comprehensive Peak-Value Data Logging: Allows operators to pull historical drift profiles directly from the panel screen, identifying dirty sensors before they cause loop fault alarms.
Frequently Asked Questions (FAQ)
Q1: Are the Simplex 4098-9714 sensor and 4098-9789 base sold together in this SKU bundle?
A: Yes. This product package includes both the addressable photoelectric sensor head and the matching wired terminal base, giving you a complete field kit ready for site installation.
Q2: Can I substitute a heat sensor into this same base during building construction phases?
A: Yes, absolutely. TrueAlarm standard bases feature fully interchangeable terminal paths, allowing maintenance teams to temporarily swap out smoke detectors for heat sensors to avoid dust contamination without breaking loop addresses.
Q3: Which Simplex fire control panel families are compatible with this detector loop kit?
A: The bundle is fully compatible with modern intelligent addressable systems, including the Simplex 4007ES, 4010ES, and 4100ES network panel series.
Q4: How does the built-in LED indicator behave under different loop conditions?
A: Under normal operating communication, the integral red LED pulses gently to signal active polling. If an alarm condition or a specific device fault is determined by the panel, the LED turns solid red.
Q5: Does this device require an independent external 24V power supply line?
A: No. Operating power and digital communications are drawn directly from the two-wire addressable IDNet/MAPNET loop line, saving substantial installation wiring costs.
Q6: What is the recommended sensor spacing guidance on smooth, flat ceilings?
A: In accordance with standard NFPA 72 guidelines, an initial layout spacing rule of 30 feet (9.1 meters) can be used as a smooth ceiling engineering baseline.
Q7: Where is this premium fire alarm hardware manufactured?
A: This product is part of the premium global security portfolio of Johnson Controls and is manufactured in Mexico.
