Complete Security Essex provides and installs smoke detectors for your home. We provide the following smoke detectors:
- Optical smoke detectors are most widely used and is more suited to detecting a slow burning fire which gives off larger smoke particles. It acts as a light detector.
- Ionisation smoke detector, which are beginning to be phased out, detect a quick burning fire which generates more heat and thinner smoke particles.
- The Aspirating smoke detector draws air from an area via a network of pipes which have sampling holes.he ASD can detect very small amounts of smoke and has a high sensitivity. The smoke is drawn through the holes in the pipes and back to a central aspirating detector. This is a common choice for areas such as computer suites, telecommunication room’s etc where the earliest possible warning of a fire is crucial to protect such sensitive equipment.
- The combined detector looks for both heat and smoke, this is seen as a replacement for the ionization detector. Some panels can be programmed to make a combined detector a heat during the day and smoke at night time.
The manual call point:
The red box on the wall that everyone is familiar with. In the event of a fire a person would break the glass in the unit which in turn activates the fire alarm. Most commonly found at all exits to the outside of a building.
Comes in two variants and are most commonly found in kitchens, boiler rooms or un clean environments. They come as Rate of Rise which detects a rapid increase in temperature or fixed temperature which will only activate after the room temperature exceeds a pre determined temperature set into the detector.
The alarm sounder:
Normally red and alerts occupants audibly to a fire. These can be supplemented by visual alarms ( flashing beacons ) where areas can be normally noisy i.e. factories or DDA compliance. General sound level required is 65 DBa or 75 DBa in a room of sleep at bed head level. The sounder can also be integrated with a smoke or heat detector making it an ideal option for bedrooms where the owner might not want to see a red sounder on the wall.
Normally used in large areas such as warehouses. The beam detector can emit a beam reaching up to 100m in length from one end of a building to the other and can cover 1500m2 with a single unit. The beam is optical and when obscured by smoke (obscuration) will activate the fire alarm.
A wall mounted transmitter can be mounted up to 25m high (or 40m in P systems with Fire Brigade response time is within 5 minutes). This emits a beam to another wall mounted receiver at the other end of the building or a reflective plate which bounces the beam back to the other unit.
