Interconnecting DSW Series smoke alarms
Interconnecting alarms increases householder safety.Ther are a number of important issues regarding interconnection to note:
1. Only use DSW series alarms together.Other brands may operate on a different interconnect voltage and not interact property.
2. The DSW series of smoke alarms put a 8V-9VDC alarm interconnect signal over the I and N wires.All interconnected alarms need to be on a single circuit and must share a common neutral.
3. Up to 40 alarm over 150 metres may be interconnected.
4. Read all instructions supplied with every DSW series smoke alarm,before installation.
|DSW2288 applications and usages
|Technology : Uses no radioactive material,Instead,uses a light emitter and receiver to delect smoke.If no smoke particles are present,no light reaches the receiver.When smoke particles are present some light is refiected or fefracted onto the receiver,triggering the alarm.
Advantages: Are sensitive to large smoke particles associated with smouldering fires.Will provide earlier warming than an ionization alarm in these conditions.
Disadvantages: Slower to respond to fast flaming fires.More prone to dust or insect contamination than ionization alarms.
Where to use: Smoker's bedrooms,Small confined apartments,Near kitchens,Family rooms
Where not to use: Bathrooms,Dust or insect prone areas
