b) General emergency activation input
Supervised inputs for voltage-free dry contact connection (N.O.): Restart and
Emergency.
So that the link can be supervised, the connection of the dry contact to the equipment
must be carried out by means of two external 10K resistors (supplied with theΩ
equipment), placed at the output of the fire panel as indicated in the illustration 6.
Function: When the general emergency entrance (EMG) is activated by means of a
contact closure (0V), the equipment will automatically change from working mode to an
emergency state, and emitting the voice evacuation message through all zones of the
system. When the reset input (RST) is activated, the equipment will exit the emergency
operation mode and return to the idle state (PA).
It can be configured so the EMG input makes the combinated function. See 3.2.3
NOTE: To avoid non-desired activation problems the system does not allow the alarm
activation inputs to complete the sequence EMG, RST, EMG instantly. The second
consecutive activation will leave about 2 seconds of margin.
c) State output
These outputs are dry contacts that indicate if the equipment is in emergency or failure
state when they are closed. (N.O.)
They allow a maximum current of 350mA and a voltage of 350V.
d) RS-485/MODBUS Interface
Communication port on RS-485 half-duplex base for communication with fire control
panel. It needs to be connected by 2 twisted wires (A, B) plus a GND wire.
This port is habitually not activated, it needs a firmware actualization.
2.2.3 Speaker line outputs, zones
The equipment has 6 zone outputs. Each line connection has two terminals + and –
for the speaker connection in 100V or 70 V speaker lines.
The total power of the equipment can be distributed in the departures of zones
according to the design of the installation without exceeding the maximum limit per
output: Zones 1 and 2 500W, Zones 3,4,5,6 120W.
The connection is made by means of a 2-pin female euroblock connector and 5.08mm
pitch (supplied with the equipment). The cable section range for each pole of this
connector is: 0.5 2.5mm2 (22 12 AWG).→ →
NOTE: Output voltage (up to 100 V) can be dangerous, so a correct isolation of the
speaker lines in necessary. Test that there are not short circuits, fake contacts or ground
