| There are four types of alarms used for the security of the house: |
|
| 1.Burglar alarms |
|
| 2.Smoke alarms |
|
| 3.Heat alarms |
|
| 4.Carbon monoxide alarms |
|
| 1.BURGLAR ALARMS: |
|
| Burglar Alarms can be broadly categorized into 2 main groups: |
|
| 1) BELLS ONLY ALARMS: |
|
|
When the alarm is triggered by one of the alarm components, an outside bell or siren is activated. |
|
|
This alarm will undoubtedly inform the burglars that they have been detected and motivate them to leave. |
|
|
| 2) MONITORED ALARMS: |
|
|
Any alarm activation is passed to central monitoring station by your telephone. |
|
|
These Alarm Receiving Centers (ARC) thus alert to any potential burglary. |
|
|
| 2. SMOKE ALARMS: |
|
| There are three types of smoke alarms given below: |
|
| A)Photoelectric smoke alarm |
|
| B)Ionization smoke alarm |
|
| C)Alarms for the Deaf and Hearing Impaired |
|
| A) PHOTOELECTRIC SMOKE ALARMS: |
|
|
Photoelectric smoke alarms see the smoke. |
|
|
They detect visible particles of combustion, e.g. smoldering cigarette smoke. |
|
|
They respond to a wide range of fires, but they are particularly responsible to smoldering fires. |
|
|
Such alarms also respond to the dense smoke given off by foam filled furnishings or overheated PVC wiring. |
|
|
|
|
| B) IONISATION SMOKE ALARMS: |
|
|
Ionization smoke alarms feel the smoke. |
|
|
They detect invisible particles of combustion, e.g. from cooking toast. |
|
|
They activate more quickly for fast flaming fires with little visible smoke. |
|
|
| C) ALARMS FOR THE DEAF & HEARING IMPAIRED: |
|
|
Conventional smoke alarms are not effective in alerting those with hearing impairments. |
|
|
A visual warning device which can be interconnected to the smoke/heat alarm can be obtained. |
|
|
Some models include an intense flashing strobe light in the control panel along with a vibration pad which can be placed under the pillow. |
|
|
The vibration pad will awake the sleeping occupant in an emergency. |
|
|
The control panel will often have an ancillary socket for attaching an additional strobe light ( to give an alarm downstairs during the day) or an extra vibration pad. |
|
|
| 3. HEAT ALARMS: |
|
|
There are some areas in home where smoke alarms may not be suitable, e.g. kitchen. In these areas heat alarms are suitable. |
|
|
| 4. CARBON MONOXIDE ALARM: |
|
|
Carbon monoxide alarms are not smoke alarms. |
|
|
They may be used in addition to smoke alarms for increased warning. |
|
|
You cant see, taste or smell this alarm but low levels of carbon monoxide can make you sick and high levels can kill. |
|
|
Carbon monoxide alarms are commonly used for the detection of fire in the home. |
