device into the alarm state via
sensitivity adjustment. Device then
reports alarm as if an actual alarm
occurred. Associated outputs follow.

Associated outputs follow.
Test: Manual_Activate - Test
This provides a remote switch that
upon activation/deactivation of the TRI,
the MXL reads the module-device
address provided and performs the
operations outlined above. This use is
primarily for, but not limited to, testing
intelligent duct detectors.
The Walktest Menu
A Walktest of the MXL System enables
a qualified technician to test the opera-
tion of input points on the MXL with or
without disabling the entire fire alarm
system. Testing can be silent or with
audible feedback for:
The entire System
An ALD loop (60 subaddresses)
An XLD-1 loop (30 subaddresses)
A CZM-4 module (4 zones)
A conventional zone (individual
CZM-1B6 or CZM-4 zone)
MOI (MID)
AnaLaser zones
The Walktest menu has eight items
from which to choose. You must enter
your 1-5 digit password before you can
use the Walktest functions.
WARNING: A device placed in
Walktest is disconnected from its
usual functions. Alarm causing devices
in Walktest do NOT cause alarms until
the MXL is out of the trouble of
Walktest.
In both the silent (SIL) and audible
(wAUD) Walktest modes, information
is displayed on the Control Panel LCD
and printed on the printer (if a printer is
installed). The audible (wAUD) mode
also provides audible feedback to the
technician with the testing of each
input device. Audible feedback is NOT
included on circuits with zone coded
audibles. A system with only zone
coded audibles ALWAYS results in a
silent Walktest.
Suggested Walktest Procedure
In order to reduce the chance of
problems, the following procedure
must be followed before performing
the Walktest.
Inform the person in charge of the
MXL fire alarm system that a
Walktest is to be performed and
that part or all of the fire detection
system will be disabled. It is also
advisable (or may be required) to
notify the fire department of the
test.
