Security Tips and Industry Musings
Smoke detectors, heat detectors, panic buttons and carbon monoxide detectors are some commonly used devices that contribute to the protection of the premises, while at the same time adding an essential layer to the safety of the people who live or work there. We will take a look at the variety of life safety devices in this installment.
Smoke detectors detect the presence of smoke in the atmosphere. When they have detected smoke they will cause the security system to alert the premises with an intermittent siren tone, while sending a signal to the monitoring center. Using atmospheric sampling makes the smoke detector able to read false positives under certain conditions. Dust, water vapor and aerosols are some contaminates that can create false alarms. Care should be taken to avoid areas that may make it easy for these to enter the smoke detector. Avoid areas next to bathrooms and air vents as well as non-air-conditioned spaces. Smoke detectors are the most useful in the air-conditioned spaces of the premises. It is recommended to have at least one monitored smoke detectors
per level of air-conditioned space. As most areas have an existing code requirement s for number and location of smoke detectors which must be met before occupancy is granted, these smoke detectors are largely of a secondary system in nature. As a secondary smoke detection system, the smoke detectors are placed in addition to the currently existing units.
Heat detectors are similar to smoke detectors except that they only detect the heat produced by a fire. Because of this they are typically used for spot detection in areas that a smoke detector would not be appropriate. As heat detectors do not use atmospheric sampling they are not affected by the same conditions that may cause false alarms in smoke detectors. Areas that should be considered for heat detectors are garages, near furnaces/ water heaters, rooms with fireplaces and kitchens.
Carbon monoxide (CO) detectors detect dangerous levels of CO gas in your home or works atmosphere. These devices have gained from rapid improvements over the years. When they were first introduced you could expect 1-2 years of service before they needed to be replaced. Today their life expectancy is rated at 5-7 years. It is recommended to have at least one CO detector on the premises.
Panic buttons allow the user to quickly alert the monitoring center to send the authorities when they are activated. Panic buttons can come in a wide variety of forms depending on the needs and uses of the client. Most commonly encountered are the three panic buttons included on the keypad. One for each of the emergency response agencies. Additionally, there are single alert type buttons. These buttons are set up at install to alert a pre-arranged agency. For older clients we may set up a key fob type button to call the medical services in case of a fall. While for a business we may setup a hard wired button under a counter to call the police in case of a robbery. The variety of panic buttons available allow us to tailor the system to the specific needs of the client and their expected risks.
