System Power Indicator
A green colored SuperBrite
®
LED located directly beneath the system “RESET”.power
key switch indicates system power. When the system is operating normally, the LED will
be illuminated.
Communication Controls
There are two large (7/16”) flat metal buttons under headings labeled “TALK” and
“LISTEN” for each Area Station location in the system. The name of each Area Station
location is permanently engraved on the Master Station next to the specific buttons for that
location. Optional engraved directories identifying each Area Station are also available to
provide for future system growth or changes without having to power down the system, or
to dismantle or exchange the Master Station. These controls are only active when help has
been requested from an Area Station location. Communications from the Master Station
may be made to one or more Area Stations at the same time in order to maximize response
to emergency situations in the event that they are of a more building wide nature.
System Reset Control
A keyed switch with momentary “RESET” position is provided on the Master Station to
reset the entire system following a request(s) for help. The normal position of the key
switch is straight up or ON. The ON position of the key switch is the only position in
which the key may be removed.
If a fault occurs, the system is designed to stay “on line” and continue to provide
emergency call capability from each Area Station without the system needing to be RESET.
Area Station Indicators and Controls
The Area Station communicates directly with the Master Station. Depressing the 3”
“PUSH FOR HELP” button initiates a request for assistance from the Master Station, and
permits hands-free (from the Area Station) two-way communications between the Master
Station and Area Station(s).
Visual Indicators
The Area Station utilizes two red colored SuperBrite
®
LEDs to visually indicate that a
request for help has been generated from the Area Station location and that the “HELP
REQUESTED” LED is acknowledged from a security attendant at the Master Station.
Permanently engraved and backfill painted acknowledgement labels (“HELP
REQUESTED” and “HELP COMING”) are located next to each LED.
Audio Indicators
The Area Station utilizes a piezoelectric alarm to generate a 90 dbA signal through the
Area Station to aurally indicate to the caller that a request for help has been generated. It
will remain active until the security attendant at the Master Station initiates a response by
depressing the metal “TALK” button on the Master Station.
Communication Controls
A large (3”) domed stainless steel button surface engraved with the words “PUSH FOR
HELP” backfill painted in red is used to initiate a request for help from an Area Station.
