Combination Smoke and Heat Detector

Model Number: AH-9315 Brand Name: Horing Lih Key Specifications/Special Features: CharacteristicsMultipurpose design: when there is smoke or heat during pre-fire period, field situation will vary due to different environments. This combination design is to ensure that the pre-fire confirmation will not be affected by varying environmentsSmoke gate has a special design to obscure the strong light effectively and allow smoke to come in easily. Water vapor will not gather on the insect guard screen to cause a false alarmFeatures an accumulated water dis-charger to eliminate leakage of water from the water pipes or ceiling which may leak into the detector and cause a false alarmThis detector has passed strict quality control and repetitive testing, hence its quality is stable and highly reliableSpecification
