ACA-10N
02/Eng/01-2012
Instruction manual
1. General
The ACA-10N is an alarm device with 10 alarm inputs, allowing
connection of signallers like a horn, a flashing light, HBA (Interior
Alarm) and a telephone selector contact. Setting an alarm delay
and suppression time is possible as well as continuous monitoring
of charge and discharge current. Every 24 hours the battery
capacity is checked and an alarm is released at capacity drop
below a set value.
• Optional: ACA-OM8 module for 8 outputs.
These outputs can be used as additional telephone selector
contacts.
2. Mounting
The ACA-10N is mounted by 4 screws. Ensure that no moisture can penetrate through the screws.
The cabling must be entered through the couplings and should be kitted properly.

Initial operation - Instruction manual ACA-10N
4. Initial operation
Before starting up the ACA-10N, the positive
connector of the battery should be placed
(See 8. Wiring diagram).
The jumper on the bottom PCB makes it
possible to set the alarm at alternately horn
and flashing light (position
) or at
).
continuous horn alarm (position
Also the alarm delay and the alarm
suppression must be set by the two setting
potentiometers on the cover PCB (see figure).
The alarm delay can be set from 0-120 seconds. The alarm suppression can be set from 0-30
minutes. 24 hours after initial operation of the ACA-10N the battery will be subjected to a test. In
order to change the moment of the battery check you will have to start up the battery test by
pressing the
key for 3 seconds just at the moment the test ought to start.
The cover of the ACA-10N contains a form for completion (see figure).
The form can be used to enter one’s own alarm input designations. All
the possible signalisations of the pilot lamps also are indicated near

Explanation
HORN OFF: The key switch allows you to switch off the horn or flashing light for
good. The HBA and the telephone selector contact remain being activated.
ALARM SUPPRESSION: an alarm can be suppressed by pressing this key for a
while. Suppressed are: horn, flashing light, HBA and telephone selector contact. The
suppression time can be set from 0-30 minutes.
ALARM TEST: This key can be used to activate alarm signallers such as horn,
flashing light, HBA and telephone selector contact. Pressing this key the alarm test is
switched on. Pressing the key once more the alarm test is switched off. It is
impossible, however, to switch off the alarm in this way.
BATTERY TEST: Use this button to test the battery (test takes about 1.5 minutes).
To stop the battery test the button must be pressed a second time. Should the test
result of the battery be that its condition is below standard, an alarm signal is
activated immediately afterwards. The alarm can be removed by pressing the battery
test button again. Holding the button down for 3 seconds also resets the 24-hour
timer to 0 and ensures the battery to be tested automatically again after 24 hours. So
it is important to execute the test at the right time.
SWITCHING ON and OFF: Inputs are disconnected by turning a key and holding
down the alarm suppression button at the same time. The input is then disconnected.
The alarm remains switched off, when turning the key back after that.
The inputs are disconnected in the same way as they are connected or by holding
down the alarm suppression button for a period of 3 seconds.

the cause of the alarm is not solved within the time

the alarm input was interrupted before. The time of
interruption must at least have been as long as the
‘alarm delay time’.
HORN OFF: A flashing LED indicates that the horn and flashing light
signallers are switched off by the key switch. The HBA and the
telephone selector contact remain being activated.
ALARM or ALARM TEST: A flashing LED indicates activation of the
alarm test and enables you to check the signallers. A continuous lighting
up of the LED indicates that the alarm input is interrupted and releases
an alarm. (at once or after an alarm delay time).
BATTERY PICTURE:
• In normal operation the charging current is indicated. There are three
stages, viz. discharging (red), condition of rest (yellow) and charging
(green).
• During the battery test one of the three LED’s blinks. At the same
time the battery voltage is measured indicating three stages:
insufficient (red), poor (yellow) and good (green). The battery test
lasts 1.5 minutes. In case the battery voltage is below average at the
time of testing, an alarm will be released (all LED battery indications
start blinking).

7. Functioning
Normal operation does not release an alarm. The signallers can be tested by pressing
.
Pressing the key once more stops the testing procedure.
The battery can be tested by pressing
. Holding it down for 3 seconds sets the 24-hour-timer
at 0 and ensures an automatic battery test after 24 hours. All alarm situations offer the possibility
to switch off horn and flashing light permanently by means of the key switch.

One or more alarm inputs are interrupted.

Interrupted alarm input:
at insufficient battery voltage when testing the battery.
at lack of power.
Made visible by continuous lighting up of the
LED. From that moment onwards the alarm
delay time is also started. After elapse of the delay time the signallers are activated. Switching off
the signallers immediately interrupts the alarm for a while, which makes it possible to repair the
technical failure. When an alarm signalisation at the alarm input disappears after a while, the pilot
lamp will start burning in long intervals and short blinks indicating that not long ago there was an
alarm. The message can be undone by pressing its button.
During an alarm the battery cannot be tested. The signallers are supplied by the main power,
which avoids discharge of battery.

Battery alarm:
Made visible by the three blinking LED’s of the battery indication
passed on without delay. To remove the alarm the

key should be pressed (the 24-hour-timer
will continue operating without being modified). A poor battery capacity releases an alarm at a next
battery test.
• No main supply:
The lack of main voltage is indicated by a combined red LED (discharging) of the battery indicator
, an active ALARM LED
and suppressed ALARM buttons
that light up
continuously.
The ACA-10N and the signallers are supplied by the battery power. The battery power will last for
at least 1 hours (battery empty). After restoring the main power, it will take about 12 hours to
recharge the battery. An empty battery resets the 24-hour-timer.
Attention: in case all alarm inputs are suppressed / disconnected, there will be no main voltage
alarm.
