Status Byte Breakdown
Bit 0 = Full
1 = All amps/drivers pass, 0 = 1 or more amps/drivers fail.
Bit 1 = Partial
1 = 1 or more amps/drivers pass, 0 = all amps/drivers fail.
Bit 2 = Rotor
1 = Rotor incremented, 0 = rotor failure.
Bit 3 = Stored AC
1 = AC voltage on during tone, 0 = AC voltage off during tone.
Bit 4 = Siren On
1 = Tone generator active, 0 = tone generator inactive.
Bit 5 = System Armed
1 = Instant Status response is active, 0 = Instant Status inactive.
Bit 6 = System Power Up
1 = System power up, AC on, DC good, 0 = system power down, AC off or low
DC.
Bit 7 = Dynamic AC
1 = AC volts on, 0 = AC volts off.

Instant Status Breakdown
The data that is present at the Instant port at the time of any Instant Status response. The Instant Status
response can operate in a number of different ways. In its simplest form, an Instant Status response follows an
Instant Status command (23H) from a Central Control Station.
An Instant Status response can also be initiated by an action within a Remote Siren Station, if Switch position 6
on Dip Switch 1, on the ESC-864 electronic controller is in the "On" position. Any change in the state of any bit in
the Instant Status byte will cause an Instant Status response to occur. In this case, however, Dip Switch 2 on the
ESC-864 electronic controller must be understood. Each bit in the Instant Status byte can be disabled by a
corresponding switch position on Dip Switch 2. Switch positions on Dip Switch 2 are as follows:
Sw 1
AC voltage
On = active, Off = masked.
Sw 2
Intrusion
On = active, Off = masked.
Sw 3
Strobe
On = active, Off = masked.
Sw 4
not used
Sw 5
not used
Sw 6
Full
On = active, Off = masked.
Sw 7
Partial
On = active, Off = masked.
Sw 8
Bias
On = active, Off = masked.
For example, if AC voltage fails and Switch position 1, on Dip Switch 2 is "On", then an Instant Status
response will occur. Likewise, if AC voltage fails and Switch 1 is "Off", the Instant Status response will not occur.
The Instant Status response is transmitted from a Remote Siren Station 3 times, with 15 seconds between
transmissions, unless otherwise disabled. The Transmit Off command (24H) will disable the repeat transmissions,
if it is issued following the receipt of an Instant Status byte. Typically, Instant Status bytes Full, Partial and Bias
are masked off by switches 6, 7, and 8 of Dip Switch 2.
Bit 0 = AC voltage
1 = AC volts on, 0 = AC volts off
Bit 1 = Intrusion
1 = Cabinet intrusion, 0 = No intrusion
Bit 2 = Strobe Error
1 = Strobe error, 0 = No strobe error
Bit 3 = Supervisor Error
1 = Error, 0 = No error
Bit 4 = not used
