Modular RF Nexus Modem
The diagnostic/charger is a fully self-contained, fully
automatic microcontroller based system.
When the installation is completed and the unit is powered,
the system is automatically functional. There is no need to
have the AC present at this time, only the battery needs to be
connected. The unit goes directly in lockout mode and waits
for AC to be restored.

Alarms are acknowledged by pushing the “TEST” switch less
than one half second. This action turns off the audible alarm.
Alarm indication can only be restored by correcting the fault
or by a system re-initialization.
Manual forced tests are initiated by pushing and holding the
“TEST” switch more than one second. The 1 minute test will
start.
System initialization is done by holding the “TEST” switch
for at least 6 seconds

2.4 Diagnostic
2.4.5.1 Lamp capture sequence
Any fault condition produces an audible warning, if activated, that
consists of an intermittent beep, one second on, one second off.
The capture sequence is initiated only by a reset of the system.
This is done by holding the “TEST” switch for at least 6 seconds.
The reset also initializes the main counter. After 12 periods of 30
days, lamp capture data is renewed. This renewal takes place to
compensate for system variations when the unit ages. Renewal is
not allowed if there is a lamp failure alarm.

Every 30 days, while in charging mode, the sequence generator
will generate a command to energize the transfer relay on the
emergency lighting circuit for a variable test period depending on
the yearly sequence.

2.4.1 Open or short battery circuit
The status indicator displays steady red LED if the battery circuit
is opened or shorted.
2.4.2 Transfer module
When a transfer is initiated (brown-out, manual test or auto-test),
and the system fails to energize the lamp circuits, a system failure
is detected and the bi-color displayed a load disconnect indication.
2.4.3 Battery failure
This is a multi-function indicator all related to battery condition.
The status indicator displays 1 red blink and a pause of 5 seconds
when a wrong battery (ex: 12V battery on a 6V system). It will
also be displayed if the battery has failed a timed or forced test
(reached LVD level before the end of the test).

If the battery fails to complete the discharge test, the charger
will display a battery failure and the test will abort
The 30 days automatic test sequence is reset every time the
lamps have been turned on included the manual test.
3.2 Lamp disconnect (battery energy saver)
When in energy mode, because of a power failure or a brown-out
condition, lamps can be turned “OFF” by pushing the “TEST”
switch. If LVD has not been detected, lamps can be turned back
“ON” by again pushing the “TEST” switch.
3.3 Audible alarm
This option can be activated or not in the field. Refer to the
drawing on Figure 1 page 3 for positioning.
3.4 Remote diagnostic (Nexus)
2.4.4 Charger monitoring
The status indicator displays 2 red blinks and a pause of 4 seconds
if the charging current does not fall within limits corresponding to
the charger command state.
Charger compatible with the Nexus communication system that
allows to monitor, in real time, the status of each unit from a
computer.
2.4.5 Lamp testing (incandescent
only)
The test is fully automatic and because of that, there are some
limitations. To maintain accurate data, some conditions are to be
fulfilled prior to acquiring values from an all-good lamp circuit:
• The battery has to be at or nears full power. The program will
delay data capture for a minimum of 48 hours following any
discharge or reset.
• The charger will also wait for the charger to be in hysteresis
mode. Both conditions must be fulfilled.

4.4.1 Wireless Nexus option
4. Electrical specifications
1.
When provided with the Wireless Nexus RF option, the unit
will automatically join the local Nexus RF Mesh network on
power-up. All diagnostic functions will be then monitored
through the network by the centralized Area Controller.
2.
The Wireless Nexus system operates in the 915MHz ISM
band providing superior penetration through building
materials and ensuring network integrity.
3.
A yellow/green flashing status LED indicates an uncommissioned unit waiting to join the network.
4.
For commissioning and networking details see the Wireless
Nexus manual.
4.1 Lamp filament detection
Resolution is 10% of the full-load circuit or 10 watts in a 100 watt
load (i.e.: one lamp out of ten). No more than 5% voltage drop is
allowed in the remote lead wires.
IMPORTANT: Reset the system after a load change. See section
2.3 (Test / Silence test button) for explanation.
4.2 LVD
Low voltage battery disconnects automatically shuts down lamp
load and circuitry when battery reaches 87% of nominal battery
voltage preventing deep discharge and permanent damage to the
battery.
4.4.2 Wiring Diagram for AD charger
See picture Figure 4 (Typical wiring diagram) on next page
4.3 Voltage drop protection
When remote fixtures are connected to emergency lighting units of
less than 50 volts, circuit runs must be sufficient size to maintain a
proper operating voltage to all lamps. The maximum allowable
voltage drop should no exceed 5%. For more information, please
contact the factory.
