Power Requirements
The ADA 100 Emergency Call System has an input voltage of 120 VAC, converting to
24VDC @ 1 amp. This connection is made at the systems Relay Card Cabinet which
houses the system’s electronics.
The ADA 100 Emergency Call System also features a 24VDC battery backup system
supplying 1.0 amps for each group of ten (or multiples of 10) Area Stations to ensure
auxiliary power in the event of a power outage. Larger power supplies are included with
larger systems.
System Components
Master Station
The Master Station is a 16 gauge (0.062) 304 brushed stainless steel vandal resistant unit
that is the heart of the system from which all calls are controlled. Each Master Station
contains a 90 dbA piezoelectric audio alarm, red, green and amber colored LEDs as visual
indicators, a system RESET key switch, and engraving identifying each Area Station
location. The size of the standard (1-5 areas) flush mounted Master Station is 11” x 11”.
Master Station size depends on the number of Area Stations in the system. Consult the
manufacturer for larger Master Station dimensions.
A Master Station can accommodate up to 60 Area Stations. The baseline Master Station
accommodates 1-5 Area Stations. The next larger size Master Station accommodates 6-10
Area Stations. The next larger size Master Station accommodates 11-15 Area Stations,
then 16-20 Area Stations and so forth, up to 60 Area Stations. Multiple Master Stations
may be used to accommodate larger systems. Master Stations should be mounted in an
appropriate and secure area (manned location) typically adjacent to other security
equipment.
Area Station
Area Stations are 9” x 9” 16 gauge (0.062) 304 brushed stainless steel vandal resistant
units that are used to communicate directly with the Master Station. Each Area Station
features a 90 dbA piezoelectric audio alarm, red colored LEDs as visual indicators and a
large (3”) domed stainless steel engraved and backfill painted panic button labeled “PUSH
FOR HELP”. Area Stations should be mounted in areas where they are visible and easily
accessible by anyone needing help.
Relay Card Cabinet
The standard size Relay Card Cabinet (12” x 12” x 4”) holds up to 10 Relay Cards, one per
each Area Station in the system. Larger systems will use larger cabinets with more Relay
Cards.
Relay Card
The Relay Card is the electronic brain for an Area Station; one card is supplied for each
Area Station used in the system.
