Magnetic contact with radio transmission

The magnetic contact wireless MAG 4MHCS is a sensor able to detect opening or closing doors or windows
and transmits via radio a alarm signal. It is composed of two distinct elements: a case containing the
magnetic contact and electronic card normally placed on the frame of the fixture and a small permanent
magnet to fit on the mobile element of the fixture. The working is based on the closing and opening of a
sensor capable to operate within a 5mm radius from the permanent magnet.
MAG 4MHCS is battery power supplied and designed to ensure autonomy of 3-5 years, it is always internally
controlled by a meter charge that forwards via radio the battery life time and warns by a beeper and LED,
the alarm of discharged battery.
It’s available a double auxiliary block terminal independent from internal magnetic contact, where it’s
possible to connect a second sensor, eg further magnetic contact, sensor for rolling shutters or other type of
sensor that uses a free NC contact. Internal electrical card manages this independent contact and the event
of case opening and consequent sends a unique radio code.
Other functionalities are: the tamper, which is activated in the event of tampering of the enclosure, the tear
can be activated by removing of the sensor installed, a software periodic supervision that communicates via
radio the battery status, tamper, magnetic contact independent alarm condition.
The radio protocol is a rolling code type, programmable on demand, and unique code programmed in AUREL
for each sensor.
A LED shows radio transmissions, alarms and test.

HOW IT WORKS

Jumpers 1 and 2 (see JP1 and JP2 in picture one) allow to set several kind of works for test and alarm
phase

.

FUNCTION JP1 JP2

RADIO MODE CLOSE OPEN
CALIBRATION FOR MAGNETIC SENSOR CLOSE CLOSE
SUPERVISED OPEN CLOSE
NORMALY WORKING X X

RADIO MODE:

It’s a function used during learning procedure to get the radio code in the matched

receiver and to verify the quality of the radio connection.

CALIBRATION OF MAGNETIC SENSOR:

It’s a function used during learning procedure of the
sensor that helps the installer to place the permanent magnet near the magnetic contact.
It is triggered by the closure of JP1 and JP2, the LED switches on when the magnet closes the magnetic
contact and switches off when the contact opens. No radio transmission is activated.
After five minutes from the starting of the procedure, the sensor will come back to the normal function.
To start again the function, disconnect and fit again JP1 and JP2 contacts.

SUPERVISION FUNCTION:

It sends to the receiver side a signal to give a feedback of the status

battery and the status of the magnetic, tamper , tear contacts.
It’s activated from the closing of JP2 contact, it’s foreseen a transmission each 60 seconds independent from
the alarm signal.

MAIN WORKING:

Normally is activated after the fitting of the battery or when “RADIO MODE” AND

“CALIBRATION OF MAGNETIC SENSOR” functions are finished. The sensor sends the status code when there
is a variation of the operation, eg opening or closing of any contact (see "SPECIFICATIONS OF THE RADIO
CODE). The led switches on for 100 ms to show the transmission. The time transmission is about 0.6 sec.

Acoustic and luminous signal.

Within the MAG 4MHCS are present a buzzer and a red LED with the following functions:
BUZZER: Used to signal low battery and it’s activated when the battery voltage drops below 2.1 volts or at
the procedure for supervision (every 60 minutes).
LED is activated for each radio transmissions (alarm, supervisory radio test). If the case of low battery
(below 2.1 V), it blinks quickly for 2 seconds every 5 minutes. The calibration function of the magnetic
sensor remains on when the magnetic contact is closed.

Standard setting up

Installation:

1) Remove the front cover and the screw securing the card (see fig. 2).

2) Place the bottom of the sensor on the frame of the fixture, making sure to turn the magnetic sensor to
the moving part of the frame where the permanent magnet is placed. Then mark the holes printed on the
bottom box (see fig. 3), 5-6 mm drill with drill and secure the bottom (Fig. 3-4).

3) Remount the card, block with the screw, close JP1 and JP2 contacts (ready for “magnetic sensor
calibration” mode) and mount the battery and the plastic cover.

4) Place the permanent magnet on the mobile part of the fixture trying to match the reference marks in the
case of the sensor and permanent magnet. If the magnet is sufficiently close to the magnetic contact, LED
will switch on indicating the closure of the magnetic contact. However, the sensor will not be installed at a
distance greater than 30mm from the permanent magnet.

Learning procedure and radio test:

Prepare the receiver side in the learning mode.
Activate the "radio mode" of the MAG 4MHCS by closing JP1 and JP2. The radio will operate for about 30
seconds.
Note: The installation of MAG 4MHCS on metal frames can cause radio performance losses. In this case it is
advisable to install the magnetic sensor away from screening components and connect an external magnetic
contact to the auxiliary input (see Figure 5).

Installation with connection to the auxiliary input.

MAG 4HCS has in its internal a double block terminal where you can connect a NC contact.
The figure above shows a typical application of sensors connected in series to help protect a single device
with multiple windows.
The various contacts must be connected in series, the opening of one of them will cause the alarm.
This scheme will not allow the state opening of each frame.
This contact can also be used with any other type of sensor that has a dry contact output NO / NC.

Battery substitution

The substitution of the battery must be carried out when the sensor transmits the low battery alarm by radio
signal or led or buzzer. However the battery is not completely discharged and will ensure a couple of weeks
of working.
To substitute, procede as follow:
remove the top side of the case, replace the 3V mod. CR2032 litium battery being careful to the polarity, see
picture number 6. To obtain a higher time life, five years life time batteries are advised. The accidental
reversal of polarity of the batteries does not cause the breaking of the circuit and discharging them. In the
case of loosing of substances , remove it taking care to not get in contact with them. Throw used batteries
in respect of the normative. See the section 'Information for users'.

Radio code features

MAG 4MHCS implements the Microchip's Keeloq rolling code with Aurel manufacturer code, customizable on
request. The parameters of the protocol Microchip Keeloq are not disclosed and are available on request.
The radio transmitted codes related to different functions of MAG 4HCS are described below. Consider that
the S0-S1-S2-S3 codes refer to the 4-bit encoding used by Keeloq (see the documentation about the
Microchip Keeloq):

MAGNETIC CONTACT: represented by S3 bit and it has high logic level when the contact is opened or low
logic level when the contact is closed.

TEAR AND TAMPER CONTACT: they use the same bit S2 and it goes high when one of the two contacts
is open. S2 goes low when both are closed.

AUXILIARY INPUT: represented by S0 bit and it goes high when the contact is open and low when it’s
closed.

RADIO MODE: all bits (S0-S1-S2-S3)are at “zero” logic level and this function is used for test radio
transmission or learning the radio code in the central unit.
