PROTOCOL FEATURES

Control Unit Interrogation and Command:

3 bits of command instruction and the 7- bit address are

issued by the control equipment following an initiating pulse.

Interrupt Warning:

Notification that an XP95 manual call point or XP95 Mini

Switch Monitor (interrupt) has been operated.

Analogue Value Report:

Status continually reported.

Input Bits Reporting:

Field devices advise control equipment of actions they have

taken. For smoke and temperature detectors, these confirm

compliance with the output command bits. Bit information

depends on device type.

Automatic Type Identification:

The device being interrogated replies with a 5 bit type

code, allowing up to 32 device types.

Address Confirmation:

The 7- bit address (up to 126 devices per loop) of the

detector responding is confirmed back to the control unit.

XP95 Device Flag:

Tells the control equipment that more information is available.

Alarm Flag:

For accelerated alarm reporting.

Parity Error Check:

For received message accuracy.

Interrupt or Alarm Address:

Provides fast location of a device in alarm state.

ENGINEERING FEATURES

High Level Integration:

ASICs technology for lower component count.

Zero Insertion Force Base:

For easier installation and maintenance.

Ease of Maintenance:

Snap lock chambers for easy cleaning.

Surface Mounted Components:

For long life and high reliability

Latest Data Reported:

As well as free running data update, device will update

data when the preceding device is being interrogated.

XPERT Card Addressing:

For fast reliable installation and service.

Unobtrusive Design:

For elegant designs in modern buildings.
