9.4 Connecting Call Stations
The fireman call stations can be connected to the rear side pluggable screw terminals (EV-EVAC1,
Fire Mic1) or to the front side DIN connector (5-pole, 180°, Fire Mic2) for EV-EVAC MIC. Pin layout
is as follows:
Pins 1 + 3 = MIC capsule
Pins 4 + 5 = switch input (PTT)
Pin 2 = GND, shield
The subzone call stations EV-P4 are to be connected to the so designated pluggable screw
terminals or to the RJ45 connector. Up to about 30 EV-P4 can be connected in parallel. The RJ45
connectors pin layout is the same as the screw terminals:
1 = BUSY
2 = GND
3 = Capsule (CAP) hot
4 = Capsule (CAP) cold
5 = Key1
6 = Key2
7 = Key3
8 = Key4
The cable length with EV-EVAC1 and EV-P4 can be extended up to maximum 500 Meters. Of
course only well screened and twisted pair cable has to be used such as communications
installation cable F/UTP 4x2x0.8mm or CAT5/6. Due to analog signal type, there will be a high
frequency cut when extending cable length to more than about 200 Meters.
The EV-PAGE call stations (80 channel) are to be connected as well to pluggable screw terminals
as to a RJ45 connector. Up to 8 EV-PAGE can be connected in parallel. The RJ45 pin layout is
also the same as the screw terminals:
1 = +15V DC
2 = GND (0V[15V])
3 = RS485 +
4 = RS 485 –
5 = GND
6 = EVAC
7 = Capsule (CAP) hot
8 = Capsule (CAP) cold
Maximum cable run is 200 Meters. Only well shielded twisted pair telecommunications cable may
be used such as F/UTP 4x2x0.8 or CAT5/6. It is possible to extend the cable run up to 500 Meters,
if the DC power supply (normally 15V DC) will not drop below 14V at any call station. If so, please
add further pairs of wire in parallel to the supply leads. Here is also valid: cable runs with more than
about 200 Meters will cause a high frequency loss.
9.5 Connecting Program/Background music sources and AUX with request contact
The IN PRG cinch connector is the input for program/background music. Line sources with a 0 dBu
(=0.775B RMS) level are to be connected.
The AUX cinch connector is for line sources providing a dry contact for request such as a
spotplayer for instance. Line level has to be 0.775V RMS too. The contact must be wired to AUX
screw terminal and GND.
9.6 Further Control Inputs
To start stored alarm messages (for instance evacuation) the screw terminals EMY1 and EMY2
(against GND) can be used. The message is running as long as the control input is shorted to
GND. All wiring is monitored, this is why 2 resistors have to be added to a switch as shown below:
