System Description
The ADA 100 is a modular, hands-free Emergency Call System with dual audio and visual
alarms and built in supervision capabilities designed to comply with the Americans with
Disabilities Act. The ADA 100 Emergency Call System is a hard wired system needing
only a simple connection to AC power and/or auxiliary DC power to operate. The system
can be operated independently of any other building systems or interfaced with your
existing annunciator or fire alarm system.
Each ADA 100 installation consists of at least one Master Station
,
one or more
Area
Stations
,
Relay Card Cabinet (with one Control Board and one or more Relay Cards, and
Battery Backup Power Supply System. Each Master Station and each Area Station are
mounted using either a Flush Back Box or Surface Mounting Collar. Tamper Proof
hardware and a Tamper Driver (socket only) are also included with each system. Optional
system components include Braille Instructional Signs in 18 gauge stainless steel frames,
Illuminated “Area of Rescue Assistance” signs with universal mounting hardware and
independent battery backup system (also available without battery backup), telephone
dialers (4 number capacity) and remote Area Station mounted strobe lights.
System Operation
All conversations are controlled at the Master Station using the specific “TALK” and
“LISTEN” metal buttons identified for each Area Station location in the system.
Operation of the system is confirmed at both the Master Station and Area Stations by
means of audio and visual indicators. These indicators verify to the security attendant that
the system is fully operational. They identify locations requesting assistance, alert the
security attendant to respond to the request(s) for help from the Area Station location(s),
and establish two-way communications. All conversations at the Area Station are “hands-
free” after the initial system request.
Master Station Operation
When the system is activated by a request for help from an Area Station, a 90 dbA sound
will occur through the Master Station and a steady red LED identified with a specific Area
Station location (engraved label) will illuminate. The security attendant operates the
system by depressing the metal “TALK” button on the Master Station for each specific
Area Station location to establish a dialog with the person in need of help. This will:
•
Silence the piezoelectric alarms at both the Master Station and the Area Station
•
Illuminate the red LED labeled “HELP COMING” at the Area Station
•
Open up a two-way communication channel with the Area Station so that the
security attendant can converse with the person requesting help
•
Depressing the metal “LISTEN” button at the Master Station enables the security
attendant to hear the person’s response
Resetting the system is accomplished
by
turning the reset key at the Master Station. This
will extinguish the “HELP COMING” light(s) at all Area Station(s) and the Master
Station.
