The MP-WDC series amplifiers can be powered either at 100-
240VAC 50/60Hz through the IF-8P4ETH/0 chassis, or at
24VDC through an individual power strip for each amplifier
module.
Each amplifier incorporates short-circuit/overload protection on the speaker line, as well as thermal protection to prevent failure
due to overheating.
Optionally, the IF-8P4ETH/0 can have 4 analog audio inputs by incorporating the IF-PIA4 module, and 10 input contacts and 4 output
contacts by incorporating the IF-PCT module.
It is possible to expand the capacity of the IF-8P4ETH by adding IF-8P4/0E slave units (4 additional amplifiers per slave unit, up to a
maximum of 10 IF-8P4/0E units). To do so, the IF-8P4ETH/0 must be equipped with the optional IF-PLINK module (not included).

Safe handling with batteries:
•Warning! Improper use of battery may lead to explosion. Replace the batteries with the same or equivalent type only.
•Batteries may endanger life if swallowed. If a battery is swallowed, seek medical assistance immediately.
•Before inserting the batteries, check whether the contacts in the device and batteries are clean and, if necessary, clean
them.
•Only use new batteries.
•Do not use rechargeable batteries
•Never try to recharge normal batteries. There is a risk of explosion!
•Never expose batteries to heat sources (e.g. radiators) or direct sunlight. There is an increased risk of leakage!
•Never short-circuit the batteries.
•Never throw batteries into a fire.
•Do not disassemble or deform batteries.
•If the equipment is not going to be used for long periods, remove the battery.
•Remove leaking batteries from the device immediately. If battery acid leaks out it is essential to avoid contact with the skin,
eyes and mucous membranes! If the acid does come into contact with skin, immediately rinse the affected areas with plen-
ty of clear water and consult a doctor immediately. There is a risk of acid poisoning and acid burns!
•Remove exhausted rechargeable battery from the device immediately! There is an increased risk of leakage
•Do not throw used batteries into the household waste. The batteries must be deposited in a collection point for used bat-
teries.
4. PLACEMENT OF THE BATTERY
From the PA Manager software it is possible to create message time schedules and volume time schedules, and send these schedules
to the equipment. In this way, a server PC is not necessary to activate the time schedules, but the equipment activates them
automatically.
For this purpose, the equipment incorporates a RTC (Real-Time Clock) whose function is to maintain the current time. To keep the
RTC powered even if the equipment is turned off, a 3V lithium battery type CR2032 supplied with the equipment must be inserted.
It is advisable to replace the battery of the equipment at least every 5 years.
Battery placement procedure:
1) Disconnect the power supply to the equipment.
2) Open the battery compartment by
removing the screws that hold it.
3) Insert the battery respecting
the polarity indicated in the
drawing in figure 3.
4) Once in place, reinsert
the battery module.

6.3.Connection of loudspeaker lines
The equipment has four channels (one for each amplifier) for the connection of loudspeakers with 100V line transformer.
Each channel has 2 loudspeaker line outputs marked A and B. The rated power of the amplifier is split between both line outputs.
This allows the connection of redundant speaker lines for the same zone.
When working with 100 V lines, it is necessary to remember the following:
The loudspeakers must be provided
with a line transformer.
The total connected power will be the
sum of the powers absorbed by the
loudspeakers and must be between 50%
below and 10% above the rated power of
the amplifier.
The IF-8P4ETH/0 allows monitoring the status of the loudspeaker lines and determining their status (open line, short circuit, low
impedance, high impedance or line in good condition). If a line fault is detected, it automatically disconnects from the corresponding
amplifier, while notifying the system of this occurrence.
Each channel also has a connection for a backup amplifier. The backup amplifier automatically replaces a failed amplifier when the
IF-8P4ETH/0 detects the failure. The backup amplifier must have a power rating equal to or greater than the power
rating of the largest of the amplifiers it is to replace.
The monitoring functionalities, both speaker line and amplifier, are activated and configured using the PA Manager or PA Manager
Configurator software.

6.4.Input contacts INPUT CT 1, 2 and 3
The unit has 3 input contacts (INPUT CT 1, 2 and 3).
Functionality and idle status (NC/NO) are configured through the PA
Manager software. They can be configured as general purpose
contacts, or in evacuation systems, as emergency mode activation
contacts, evacuation message activation...
If desired, the system can monitor these contacts (short circuit or open
line detection).
The detection time of the activation pulse of the input contacts is
configurable through the PA Manager software (0-50-100-200-200-
300-400-400-500-500-1000-1500-2000 milliseconds).
Follow figure 20 for connection. If you wish to monitor the contact,
follow figure 21.
6.5.Output contacts OUTPUT CT 1A, 1B, 2A, 2B, 3A y 3B
The unit has three output contacts. Each contact has two terminals (A
and B). By default, they are configured as dry contacts, through a 3k3
resistor.
Functionality and idle status (NC/NO) are configured via the PA
Manager software. They can be configured as general purpose
contacts, or in evacuation systems as fault notification contacts,
Emergency Mode activated indicator...
For connection follow figure 22.
ATTENTION:
Max. DC charging current: 150 mA.
Max. charging voltage DC or AC peak: 350V.
6.6.FAIL contacts
Relay indicating system failure.
The COM contact linked to the NO contact indicates that there
are no alarms in the system. If, on the other hand, COM is tied to
NC, it indicates equipment shutdown or alarms detected.
Maximum DC load current: 150 mA.

6.7.CAN bus
The IF-8P4ETH/0 communicates with the IF-8P4/0E units via a CAN bus. The data transmission rate between the IF-8P4ETH/0 and the
IF-8P4/0E slave units is 500 kbit/s (default rate).
With the other CAN peripherals in the installation (MD-30C*, ME-200C*, NS-CAN... desks) the baud rate should be 33.333 kbit/s,
which allows a longer distance to be reached when connecting the peripherals to the IF-8P4ETH/0. For this reason, to communicate
with the MD-30C, ME-200C and NS-CAN peripherals, the baud rate of the IF-8P4ETH/0 must be set to 33.333 kbit/s, as explained in
section 8. EQUIPMENT START-UP.
In installations where IF-8P4/0E devices coincide on the same CAN bus
with other CAN peripherals (MD-30C*, ME-200C*, NS-CAN...) it is
necessary to install the external speed adapter model CAN-AV (code
A465AV) to match the transmission speed between devices.
* Attention: To connect MD-30C or ME-200C microphone desks, the IF-
8P4ETH/0 must have the accessory module for auxiliary audio inputs model
IF-PIA4 (code M249PIA) installed.
