• Removable sensing chamber for easy maintenance
• 360° visible fire LED
• Supports remote indicator connection
• Magnetic test functionality
• 2-level sensitivity (EN 54-7 compliant at level 1)

Description

DC-9102E Conventional Photoelectric Smoke Detector is a new-generation product with a built-in microprocessor. It provides stable and reliable fire detection using advanced fire judgment algorithms.

When smoke is detected, the detector sends a signal to the control panel via current variation and activates the LED indicator until reset.

It uses light scattering theory and includes drift compensation to maintain consistent sensitivity despite environmental changes such as dust, humidity, and temperature.

Connection and Cabling

• Terminal 1: Positive input from power supply or zone monitor
• Terminal 2: Output to next detector and remote indicator
• Terminal 3: Negative input/output
• Terminal 4: Remote indicator negative

Recommended Wiring: Use 1.0mm² or higher fire-resistant cable in conduit.

Installation

1. Fix the base using screws
2. Align detector with base
3. Rotate clockwise until locked

Application Notes

• Do not connect directly to 24VDC without current limiting
• Default sensitivity: Level 1
• Configurable via P-9910B programmer

Parameter Setup

Parameter	Sensitivity	LED Status
1	Level 1	ON
2	Level 2	ON
129	Level 1	OFF
130	Level 2	OFF

Testing

• Test after installation and periodically

1. Magnetic Test: Use magnet tool near detector
2. Smoke Test: Apply smoke to detector

After testing, reset by cutting power for at least 10 seconds.

Maintenance

• Clean detector at least once per year
• Keep dust cover on until system is active
• Clean sensing chamber if nuisance alarms occur

1. Open detector cover
2. Remove sensing chamber
3. Clean with alcohol or water
4. Reinstall components
