(100-240Vac 50/60 Hz) and 24VDC.
Pre-recorded messages resident in the equipment,
remotely updatable by Call Point software via IP, located
in internal Micro SD memory (16 GB).
DSP and monitoring functions.
DSP functions:
Volume, bass and treble controls or 10-band graphic
equalizer via Call Point software.
Surveillance functions:
-Loudspeaker line monitoring: (open line, short circuit,
low impedance, high impedance or line in good
condition.
-Monitoring of the amplifier status, analysing the audio
signal to detect whether the power amplifier has gone
into protection or is switched off.
-From the pre-recorded messages stored in the
equipment.
Digital audio reception via IP connection.
Receiving and sending control data via IP connection.
CAN bus communication with peripherals (NS-CAN and
NSD-CAN, ME-200C*, MD-30C*).

Handling batteries properly:
•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
plenty 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
batteries.
3. PLACEMENT OF THE BATTERY
From the Call Point software it is possible to create message time schedules and volume time schedules, and send these schedules
to the equipment. In this way, it is not necessary a server PC to activate the time schedules, but it is the computer that activates
them automatically.
To do this, the equipment incorporates an RTC (Real-Time Clock) whose function is to maintain the current time. To keep the RTC
powered even if the equipment is turned off, we must place a 3V lithium battery type CR2032 supplied with the equipment.
It is advisable to replace the equipment battery at least every 5 years.
Battery placement procedure
1) Disconnect the power supply to the equipment.
2) Unscrew and pull out the battery module.
3) Insert the battery according to the polarity shown in
figure 3.
4) Once it is in place, reinsert the battery module.

4.3.INPUT CONTACTS 1, 2 and 3
The device has three input contacts.
Functionality and idle status (NC/NO) are configured via the configuration 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 via the Call Point or Call Point Configurator software
(0-50-100-200-300-400-500-1000-1500-2000 milliseconds).
Follow figure 6 for connection. If you want the system to monitor the contact (short-circuit or open line detection), follow the
diagram in figure 7.
4.4.OUTPUT CONTACTS 1A, 1B, 2A, 2B, 3A and 3B
The equipment has three output contacts configured as dry contacts. Each contact has two terminals (A and B).
Functionality and idle status (NC/NO) are configured via the Call Point or Call Point Configurator 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 8.

4.5.BUS CAN
Data communication bus between the equipment and CAN peripherals (NS-CAN, NSD-CAN, MD-30C* and ME-200C*).
* If MD-30C or ME-200C microphone desks are to be connected, the IF-7WDCETH must be fitted with
the accessory module model IF-MER (code M240MER).
The default CAN communication speed set in the IF-7WDCETH is 33,333 kbit/s, which allows communication with NS-CAN, NSD-
CAN sensors and MD-30C or ME-200C microphone desks.
4.5.1. Connecting NS-CAN or NSD-CAN peripherals to the IF-7WDCETH
For CAN bus connection follow
figure 9. The use of a twisted pair,
shielded cable AWG24 is
recommended.
4.5.2. Connection of CAN microphone desks (MD-30C and ME-200C) to the IF-7WDCETH
ATTENTION: ONLY IF THE IF-7WDCETH IS INCORPORATED WITH THE OPTIONAL IF-MER MODULE
(LOCAL ANALOGUE INPUTS FOR MUSIC AND PAGING AND SURETY PAGING RELAY)

4.6.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
(Figure 11).
Maximum DC charging current: 150 mA.
Maximum DC or AC peak load voltage: 350V
4.7.Connection of loudspeaker lines
The equipment has a 100V high impedance speaker line connection.
Connect the speaker line between the "0" terminal and the "100V" terminal.
When working with 100 V lines, the following must be remembered:
The loudspeakers must be equipped with a line transformer.
The total connected power shall be the sum of the powers absorbed by the loudspeakers and should be between 50% below
and 10% above the rated power of the amplifier.
