The JANUS Line Powered ADA Telephone is a hands-free communication device designed for elevator systems, ensuring compliance with ADA (Americans with Disabilities Act) requirements. It functions as an emergency phone, allowing occupants to communicate with an answering service or designated contact in case of an emergency. The phone is line-powered, meaning it draws its operational power directly from the telephone line, though optional battery and external power supply configurations are available for enhanced functionality or specific line conditions.
Function Description:
The primary function of the JANUS ADA Telephone is to provide reliable, hands-free communication from an elevator car. When activated, typically by pressing an emergency button, the phone automatically dials pre-programmed numbers to establish a connection with an answering service or emergency contact. It features a speaker and microphone for two-way voice communication. The device also includes LED indicators to provide visual feedback on its status, such as "Call in Progress" (Red LED) and "Alarm Received" (Green LED).
The phone supports various programming methods, including calling the elevator phone to program it (Method A) or using the on-board keypad (Method B). Programming allows for setting up phone numbers, an identification code, a new password, and recording a location message. The location message is crucial for informing the answering service of the elevator's specific location.
Optional features include auxiliary outputs (AUX1 and AUX2). AUX1 can be programmed to activate based on the status of the Red or Green LEDs, or when the phone turns ON/OFF, providing flexibility for integration with other elevator systems. AUX2 is designed for phone line monitoring, closing if the telephone line drops below 2 volts, is disconnected, or shorted for more than 15 minutes. This feature requires an optional 12VAC power supply and a jumper on the LM connector.
The device is available in multiple styles:
- Box-Less Style (PNB): Designed for mounting directly on the car station, with a separate red lens cap and bezel for the LED.
- Box Style (PBX): A complete unit mounted in a phone cabinet on the car station.
- Flush Mount Style (PSS/PSL): Designed to be flush-mounted into a cutout on the car station.
- Surface Mount Style (PSM): Designed for surface mounting on a wall.
