An elevator emergency communications system, often in the form of an emergency telephone (also known as intercom), is a system used in elevators to contact a certain group in case of an emergency.
Overview[]
The emergency communication system can consist of either a phone in the control panel (often hidden in a compartment behind a door, common in the US) or an intercom.
The intercom/phone is usually set to dial the security office/maintenance department or the elevator company (also known as elevator remote monitoring), although there are cases where it is set to dial the emergency number of the country the elevator is located in. In some countries, for example, Australia, the phone button may need to be held down for 5 seconds or more to actually call for help; this is to help prevent accidental false alarms.
For the year of changes and public awareness of the accessibility, some of the intercom will have a indication for the people who has hearing impaired. Comply with ASME A17.1-2000[1] or BFA 2008[2].
Interestingly, in order for the elevator to make a call, it needs to have its own phone number, which has lead to some individuals or telemarketers calling an elevator by accident.
Proper usage[]
- When you are stuck in the elevator
- A medical emergency in the elevator (e.g. cardiac arrest, often in hospitals only)
Incorrect Usage[]
- Chatting to your friends in the lobby
- Prank calls
