Octalarm-T2 / T4 / T8 / T16
16.3.3 Input external reset contact
Input in order to reset the Octalarm by remote control. Just like when pressing the reset key on the
operation panel, the report will be interrupted as soon as the contact is made. The input only reacts to
the closing of the contact. A subsequent report will thus not be blocked in case the contact remains
closed.
16.4 Connection of outputs
All the following outputs are connected through one connection cable to the 12V terminal on top of
the terminal block and another cable to the relevant output terminal. The maximum current
available for all the externally connected devices is 150 mA.
16.4.1 Output external signal light
This output is activated as long as one of the inputs is in a state of alarm and the relevant selection
key is switched on. This output remains active even after the acoustic alarm or the telephone report is
reset. The output can be used for the direct control of a 12 V flashlight or (through a 12 V relay) a large
230 V light on a manifest place indicating the alarm still applies. Switching off only takes place when
the alarm expires or when the selection key concerned is switched off.
16.4.2 External
buzzer
outputs
Outputs for connecting additional acoustic signal devices or for controlling existing alarm systems.
There are two connection options:
•
Output “NO” (Normally Open) will be active in case of an alarm. It can be used for the direct
control of 12 V buzzers. Fitting in a 12 V relay allows you to switch heavier equipment.
•
Output “NC” (Normally Closed). It is active in rest on the contrary, and drops out in case an alarm
occurs. The Octalarm can be connected to another (existing) alarm circuit using a 12 V relay on
this output, functioning through break contacts.
Both outputs are connected simultaneously with the internal buzzer.
16.4.3 External relay output
An external 12 V relay can be connected to this output. This relay can be switched on and off from a
distance by telephone.
16.5 Connection of the telephone line
Connect the Octalarm to the telephone network using the supplied telephone joint plug. Preferably,
reconnect all the remaining telephone equipment to this connector. In case of an alarm, the Octalarm
will interrupt all the connected equipment, so that the alarm is always given priority.
