Chassis Intrusion Input
The chassis intrusion input is an active high input intended for
detection and signaling of unauthorized tampering with the
system. When this input goes high, the event is latched in Bit 6
of Status Register 4, and an interrupt is generated. The bit
remains set until cleared by writing a 1 to CI clear, Bit 1 of
Configuration Register 3 (05h), as long as battery voltage is
connected to the V
BAT
input. The CI clear bit itself is cleared by
writing a 0 to it.
Rev. A | Page 27 of 56
The CI input detects chassis intrusion events even when the
ADM1026 is powered off (provided battery voltage is applied to
V
BAT
) but does not immediately generate an interrupt. Once a
chassis intrusion event is detected and latched, an interrupt is
generated when the system is powered on.
The actual detection of chassis intrusion is performed by an
external circuit that detects, for example, when the cover has
been removed. A wide variety of techniques may be used for the
detection, for example:
A microswitch that opens or closes when the cover is
removed.
A reed switch operated by magnet fixed to the cover.
A hall-effect switch operated by magnet fixed to the cover.
A phototransistor that detects light when the cover is
removed.
The chassis intrusion input can also be used for other types of
alarm input. Figure 49 shows a temperature alarm circuit using
an AD22105 temperature switch sensor. This produces a low-
going output when the preset temperature is exceeded, so the
output is inverted by Q1 to make it compatible with the CI
input. Q1 can be almost any small-signal NPN transistor, or a
TTL or CMOS inverter gate may be used if one is available.
