4.1 ESC-864 (Controller)
The ESC-864 Controller is the microprocessor-based core of the IPS. The ESC-864 houses the following:
local pushbuttons and LED indicators,
the ESC-864 controller circuit board,
the tone generator,
as options:
digital voice,
landline or RF link interfaces,
radio receiver/transceiver.
4.1.1 Local Controls and LED Indicators
Local control is available at the front panel of the ESC-864, as described below.
Local Control and Indicator Functions
Control or
Indicator
Control or Indicator Function
CLR Stops warning tones prior to completion of programmed time. Some tones "ramp down"
prior to turning off.
WAIL Siren tone. Initiates a slow rise, high-pitched tone for four seconds, followed by a softer,
winding-down for one second. This sound pattern continues for as long as the timing
duration is set.
ATK Siren tone for National Attack. Initiates a faster rise, high-pitched tone for one second,
followed by a winding down tone for one second. This sound pattern continues for as long
as the timing duration is set.
ALRT Siren tone for Alert. Initiates a quick rise then steady tone for as long as the timing
duration is set.
AIR HORN
Siren tone. Initiates a pulsing buzzing tone which blasts in intervals of 1.6 seconds for as
long as the timing duration is set.
HI-LO Siren tone. Initiates a highly pitched tone with a "Dee" sound for 0.8 seconds, followed by
a lower-pitched "Doo" sound for 0.8 seconds. This sound pattern continues for as long as
the timing duration is set.
WHP Siren tone for Whoop. Initiates a high-pitched, repetitive rise-only sound for three seconds,
then stops. This sound pattern continues for as long as the timing duration is set.
