alarm) (location) (date & time of alarm) plus indication as to whether any
further alarms exist, indicated by ‘MORE: PRESS

Function
For certain types of fault (TYPE MISMATCH and DUPLICATE ADDRESS) the built-in LED indicators
on the sensor(s) and/or module(s) for which the fault occurred will show 1-second-ON/1-second-
OFF pulses (possibly with intervening short pulses).
The built-in LED indicators on all other sensors and modules should either give short pulses or be
OFF altogether.
6.1.5
Panel ‘DEVICES MASKED’ Status
This is indicated when some or all of the sensors or modules of the system have been disabled by
means of the MASK/UNMASK operation (see Section 3.14 for details).
If the panel is a NETWORK MASTER panel this status is shown whenever devices are masked on
the network as a whole. For other panels it is shown only if devices connected directly to that panel
are masked.
The DEVICES MASKED condition continues to be shown until superseded by a higher-priority condition
or until cleared by removing all devices from a MASKed status. If an Alarm or Fault occurs and is
subsequently cleared and RESET is pressed, then if appropriate the panel reverts to showing the
SENSORS MASKED status.
The indications of the panel and external equipment are as follows:
LAMP indications:
MAINS HEALTHY (green):

SENSORS MASKED LAMP (amber):
