Description

Product Description:

YJJ SS-168/RH-169 Household 9V Independent Smoke Detector Smoke Sensor

Features:

I. Basic Information
Model: SS-168, RH-169 (compatible with the same specification, RH-169 is an upgraded version)
Principle: Photoelectric type (scattering light principle) infrared smoke detection
Structure: Infrared emitter tube + receiver tube + labyrinth enclosure, no smoke will trigger the alarm, smoke blocking will trigger the alarm
II. Core Parameters
Working voltage: DC 9–24V (commonly used 12V)
Static current: ≤8mA; Alarm current: ≤20mA
Output mode: Switching output (relay / level signal), can be connected to the alarm host
Detection mode: Photoelectric type, highly sensitive to smoldering smoke and smoky smoke
Response time: Alarm triggered after smoke concentration meets the standard within 3–10 seconds
Operating temperature: -10℃ to +50℃
Humidity: ≤95% RH (no condensation)
Size: Standard wall-mounted / embedded module, industrial / fire protection universal
Features: Anti-dust false alarm, anti-white light interference, good stability, long lifespan
III. Model Differences
SS-168: Classic old model, stable performance, high cost-effectiveness
RH-169: Optimized labyrinth structure, stronger anti-interference, low power consumption, consistent compatibility, can directly replace SS-168
IV. Applications

Specifications:

Operating voltage DC 9–24V
Static current ≤ 8mA
Alarm current ≤ 20mA
Output mode Switching output Detection
size 10.1 x 10.1 x 6.5 mm3
T90 Response Time ≤ 30s
