When the unit is powered ON there are LED’s
located on several of the subassemblies within the
cabinet that will become illuminated to indicate the
ON condition. The function of each of these indica-
tor LED’s are listed in Table 3.

The ALARM Form-C relay contacts are located on
the back panel of the unit as shown in Figure 7.
These screw terminals are intended for connection
to the customer’s supervisory and data acquisition
system. Both normally open and normally closed
contacts are available. The system will alarm when
an over current or high temperature event occurs in
a channel module or power amplifier. Also, a DAC
overflow condition can cause the alarm contacts to
change state.

The NFPA style booster system is designed to be
compliant with the national public safety in-building
codes issued in the International Fire Code (IFC
2009) and the National Fire Protection Association
(NFPA-72 2009). The booster system accom-
plishes compliance when used in conjunction with
an appropriate battery backup unit. An optional
battery backup unit is available from Bird Technolo-
gies, model number 6160-H-48-NG. Detailed
installation and operating instructions for the bat-
tery backup unit are included with the backup unit
when it ships from the factory.

The system consists of a signal booster unit as well
as the optional battery backup unit which can pro-
vide up to 24

 

hours of emergency battery operation

for the booster. The NFPA compliant signal booster
is designed to easily interface to fire alarm panels.
Five alarms are provided which are accessible
through a convenient terminal block location. The
terminal block provides a common access point to

the alarm signal relay contacts. Available alarm
functions include;

SB Failure - this is a summed alarm that is active
when any number of fault conditions arise within
the booster unit such as when an over current or
high temperature event occurs in a channel module
or power amplifier. Also, a DAC overflow condition
can cause the alarm contact to change state.

Loss of AC Power - active when the booster
switches from operating on the AC power supply to
operating on the DC battery backup voltage.

Low Battery Capacity - the source of this alarm is
the battery backup unit and it indicates that the bat-
tery backup voltage level has dropped significantly.
The optional battery backup unit is capable of pro-
viding at least 24 hours of continuous backup
power for the booster.

Charge Fail - the source of this alarm is the battery
backup unit and it indicates failure of the battery
charger. If the battery charger looses AC power
this alarm will be active. It will also indicate when
the battery will not properly charge.

Antenna Malfunction - indicates there is a loss of
cable connection integrity between the signal
booster unit and the remote antenna line sensor.
The alarm terminal strip uses screw terminals for
ease of connection. Route the alarm wires through
one of the access holes in the bottom of the box,
strip about 3/16” of insulation from each end,
loosen the screw terminal, insert and retighten.
Use #20 or #22 gauge insulated wire.

All five of the alarms use “supervising” alarm cir-
cuits. A supervised circuit includes technology that
will detect open or shorted circuits regardless of
