Integral sounder volume:
The Alert Point has 2 volume settings – High and Low: this is
determined by the position of the jumper connector
configuration show below.
High: Jumper between centre pin and bottom pin (factory setting)
Low: Jumper between centre pin and top pin
Note: Silencing the Alert Point is possible by not having the jumper fitted, but
no sound will be produced by the integral sounder during alarm, fault or tamper
conditions.
Low battery check:
The Alert Point monitors the output power of the 9V DC
battery in 16 minute cycles. If the battery falls below the
recommended power level the unit will display a fault,
emitting a periodic single beep.
Battery life:
The working life of the 9V DC battery under normal
`standby’ condition is a minimum of 15 months: it is
recommended that this battery is replaced at least every
15 months.
Battery back up:
When the Alert Point is powered by a 12-30V DC power
supply, the 9V DC battery will become a backup if the
external power is lost.
The unit will display a fault until the external power has
been restored.
External detector checking:
The Alert Point is fitted with a 5V6 Zener end-of-line
diode, enabling the unit to check for breaks in the
external wiring loop of all the linked detectors.
Even if external detectors are not fitted, the 5V6 Zener
diode must remain connected to the Alert Point,
otherwise a fault will be displayed.

Alarm Condition:
If the unit is activated in the event of an emergency (depression of
the operating element) it will immediately emit an alarm tone for
the duration selected, an activation flag will drop into view and the LED will
flash red every 8 seconds until the unit is reset.
Resetting Unit:
1.
DIL switch settings: changes will only take effect when the unit
has been powered back up using the master key switch.
2.
Silencing Alarm : If the operating element has been depressed the
reset Key is to be used to reset the unit , returning it to Standby Mode.
Note: the master key switch can be used to silence the alarm but this will turn
the unit ‘OFF’ and the alarm will continue to sound when the unit is turned
back `ON’.
Power Loss:
In the event of any loss of power, the LED will turn red and emit a short
beep every 90 seconds.
The unit will still run safely using the 9V DC battery as a back up. As soon
as power is restored the unit will automatically return to the `standby’
condition.
Low or No Battery: If the unit is reset but the battery is at low power or not attached a fault
will be indicated – the LED will turn red and the unit will emit a short single
beep every 90 seconds.
The unit automatically checks for low battery status every 16 minutes, during
this period if the battery falls into low battery condition (or is disconnected in
the presence of an external power source), the LED will turn red and emit a
short beep every 90 seconds upon detection at the end of any 16 minute cycle.
The battery will either need replacing or reconnecting and the unit reset
before it will return to a standby condition.
Step 1. Ensure that the unit is switched `OFF’.
Step 2. Insert the external power wires into the correct terminals.
Step 3. Connect the 9V DC battery. The battery must be fitted as it
will become a backup if there is a power failure.
Step 4. DIL switch SW4 – should be `ON’ (external power required).
Step 5. Turn the unit `ON’ using the master key switch.
Step 6. The LED will illuminate to a constant green indicating that
the unit is functioning correctly.
