Device Type: Wireless Interconnected Heat Alarm / Thermal Detector (Class A1)
Model / SKU: DHI-HY-HT10A-R8 (wireless interconnected variant of the HY-HT10A series)
Detection Principle: Thermistor-based temperature sensing with a 10-second sampling period
Alarm Threshold: Class A1 fire detection — triggers at +54°C to +65°C (+129°F to +149°F); monitors absolute temperature and rate-of-rise
Alarm Output: Audible and visual alarm; sound output ≥85 dB(A) at 3 m (9.84 ft)
Wireless Interconnect: 868 MHz radio frequency; up to 24 units can be interconnected; radio signal range up to 1,000 m (3,280.84 ft) in open air; when one alarm triggers, all interconnected alarms sound in unison
Silencing Function: Central push-button test and silence; also supports silencing via a working infrared remote controller (not included); silence duration 9 minutes
Indicators: Tri-color LED — Standby: green flash once per minute; Alarm: red flash once per second; Fault: red flash once per minute
Power Supply: 3V CR123A lithium battery (non-replaceable); 10-year battery life; monitoring current ≤15 µA, alarm current ≤60 mA
Operating Environment: Indoor use; –10°C to +55°C (+14°F to +131°F); humidity ≤95% RH (non-condensing)
Physical & Installation: White PC+ABS housing; dimensions φ93.8 mm × H46.9 mm (φ3.69″ × H1.85″); weight 115 g; ceiling mount
Compliance & Certification: CE, UKCA certified; compliant with BS 5446-2:2003
Key Specs: Dahua DHI-HY-HT10A-R8 wireless interconnected heat alarm, thermistor sensor, Class A1 detection (54–65°C), 10s sampling period, ≥85 dB(A) alarm at 3 m, 868 MHz wireless interconnect (up to 24 units, ~1,000 m open-air range), IR remote silence support, 9-minute silence duration, 3V CR123A sealed battery with 10-year life, LED status indication, white PC+ABS housing, φ93.8 × 46.9 mm, 115 g, ceiling mount, CE/UKCA & BS 5446-2:2003 compliant
Usage: Standalone or networked thermal fire detection in residential and light-commercial indoor spaces such as kitchens, garages, boiler rooms, attics, and utility areas where smoke detectors may cause nuisance alarms (e.g., cooking fumes or dust). The wireless interconnect ensures that when one alarm detects a fire, all linked alarms in the network sound simultaneously, providing whole-property coverage and early warning across multiple rooms or floors.
