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
Sw 2
Sw 3
Sw 4
Sw 5
Sw 6
Sw 7
Sw 8
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
Bit 1 = Intrusion
Bit 2 = Strobe Error
Bit 3 = Supervisor Error
Bit 4 = not used

REMOTE SIREN RESPONSE DEFINITIONS

Status Byte Breakdown
1 = All amps/drivers pass, 0 = 1 or more amps/drivers fail.
1 = 1 or more amps/drivers pass, 0 = all amps/drivers fail.
1 = Rotor incremented, 0 = rotor failure.
1 = AC voltage on during tone, 0 = AC voltage off during tone.
1 = Tone generator active, 0 = tone generator inactive.
1 = Instant Status response is active, 0 = Instant Status inactive.
1 = System power up, AC on, DC good, 0 = system power down, AC off or low
DC.
1 = AC volts on, 0 = AC volts off.
