BreezeACCESS Version 4.3 Operations and Administration
Manual Revision: 4.0
Alarm Parameters (GU)
The GU module serves also as the alarms control unit for the
BreezeACCESS system and auxiliary equipment. It has dry contact
connections to 4 external alarm inputs (Alarm In 1 through Alarm In 4),
that turn on upon contact closure. It also receives alarm indications
from BreezeACCESS power supply module (Alarm In 7 through Alarm
In 10), that turn on to indicate a power failure or over temperature
problem in any of the two optional power supplies. PS1 alarms refer to a
power supply module inserted in the left-most slot of the chassis. PS2
alarms refer to a power supply module inserted in the right-most slot of
the chassis. Alarm In 5 (GPS Antenna Status) is generated internally in
the GU module, and it is turned on to indicate that proper PPS (pulse
per second) timing signals are received from the GPS antenna.
The GU module can also control 3 Alarm Out relay, where each relay
has a common contact, a normally open (NO) contact and a normally
closed (NC) contact.
The Alarm Parameters menu allows access to the following sub-menus:
Alarms In Names.
Alarms Out Names.
Automatic Alarms Out Definition.
Alarms Out Control.
Show Alarm Parameters.
Alarms In Names
The Alarms In Names menu allows names for each of the four external
alarm indications that can be connected to the AL IN connector to be
defined. These names can reflect the specific environment in which the
module is being used (e.g. “Smoke Detector 1” or “Main Door”).
Each Alarms In Name can contain up to 31 printable ASCII characters
(case sensitive).
The default names are Alarm In 1 through Alarm In 4.
Alarms Out Names
The Alarms Out Names menu allows names for each of the three
external devices that can be connected to the AL OUT connector to be
defined. These names can reflect the specific environment in which the
module is being used (e.g. “Alarm Light 1”).
NOTES:
Over Temperature alarm indication is only supported by the AC power supply module.
In installations with a single power supply module, the GU module doesn’t function
(and therefore will not provide an alarm indication) upon total failure of the power
supply or upon failure of the 5 V module.
