4 Common Elevator Security And Safety
In this article, you will learn about 4 common elevator security and safety. The security system should begin at the entrance to the building. Elevators must also provide a complete building security scheme. In addition to being, it provides safe and most reliable operation.
Elevators can be integrated with each other to building security systems such as communication systems, monitoring systems, fire emergency systems, access control systems, and emergency power systems.
1- Monitoring Systems:
Monitoring systems are used to provide great safety to the people of an elevator. These systems as simple as a mirror mounted inside the cab so that people see the interior what is done inside before they entering in the elevator.
They may also be much complex as a two-way intercom system and video surveillance along with microphones that connect to the building to provide much safety. Therefore, major systems today using a closed circuit television for the visual as well as audio surveillance.
2- Communications Systems:
Most of the major systems can provide quick communication to the people when they find inside the non-working elevator. Some systems also provide a telephone in the car that directly links the elevator to the elevator repair company. While other systems operate automatically through a direct modem Link to the other maintenance company.
3- Fire Emergency Systems:
Fires seldom start in a well maintained modern elevators systems. Unfortunately, the elevator is much vulnerable to fire originating in any building. Elevator codes require door to resist fire, elevator hoistway and enough heat for people to evacuate the building.
Nevertheless, the elevator is not designed to operate several conditions like explosion, fire, water, heat. Elevators can never be used to evacuate tenants from buildings because the elevator hoistway can act as a chimney for smoke. Therefore, anyone in the elevator would be at much risk for smoke inhalation.
4- Emergency Power Systems:
For the proper safety of passengers during an electric power failure. Many buildings have emergency power systems that supply continuously electricity to lower the elevators to the designated floor. Other systems may only provide energy to operate lights, fans, and intercoms. Most hydraulic elevators have a battery-operated lowering option.
The minimum recommended emergency power supply for elevators is the capacity to move one elevator at a time at normal speed. The elevators must be able to handle a capacity load at normal speed.
In this design, the power supply is connected so that only one elevator may be operated at a time. The system is manually controlled with a selector switch. After passengers are released from the elevators, one car remains in service until full power is restored.
