Power supply.
The connexion has to be done on the "Power" input. Respecting the polarity, the AL-1 circuit requires a 12 VDC power supply correctly filtered. We
recommend you to use a short circuit power supply with low ripple level, as our FE-103 or FE-503 power supplies, which have been developed to
perfectly answer to the circuit needs. Do never use transformer or rectifier to avoid to damage the circuit.
Note: Install a fuse and a switch has it is indicated on the schedule. Both are necessary for the module's protection as well as for your own safety, as
it is required by the "CE" regulations. Consult the corresponding power supply's instruction manual.
Control inputs.
The module has 3 inputs. The length of the cable used in for their connexion has to be as short as possible. If the distance is superior to 50 cm, it will
be necessary to use shielded cable, connecting the braid to the corresponding terminal indicated with the ground symbol. In any case, the maximum
length will be to 2m.
Activation of Start and Box inputs.
indicated with the ground symbol. The activation can be also done through an external voltage signal. In such case, the signal have to be 5. DC.
perfectly stabilized, with the negative connected to the circuit's common negative, terminal with the ground symbol. The activation will be done if the
signal is equal to 0 V.
Activation of the "Alarm-In" shot input.
receives a 12 V.D.C signal. It does not allow the activation closing both terminals, but an external 12 V.D.C signal connected according to the polarity
indicated on the circuit.
The input Against Manipulating
is like to 5 V. Its operation for a switch that controls the closure of the carrier of the alarm, if it is opened without disconnecting the alarm previously,
the switch will release the two contacts for the Box input fire alarm, regardless of the expected time of entry.
Salida O_SiG.
The "O_Sig" output is activated when the relay of the circuit do it, that mean when the alarm is activated, supplying to the output a NPN transistor
signal to opened collector, destined to the activation (for instance), of Cebek telephone dialling circuits, like DA-08.
When it has happened an intrusion without deactivation code, the relay and the "O_Sig" output are activated. In the drawing, there is a connexion of
this output with a dialling circuit to warn about the intrusion, calling to the pre-assigned number, (DA-08 module).
R elay Connexion. T o control sirens or other alarm indicators.
The relay connection does not have to be contemplated like an output, it does not supply voltage. Electrically insulated from the rest of the
circuit, its function is to open or to close its contacts to allow or to interrupt the cross of an electrical signal, like a standard switch with a bulb.
The relay has three terminals: Common, Normally opened in rest (NOT), and Normally closed in rest, (NC).
You have to directly connected one of both load supply cables to the same one, the other one has to be inserted through contacts of the relays,
typically between the Common and NO, as it is specified in the fig 1, internally the relay will cut or valid the electric flux of the cable.
