1. INTRODUCTION
. INTRODUCTION. INTRODUCTION
. INTRODUCTION
MDT-122 is an automatic personal security transmitter. This
micro-processor controlled transmitter is designed for use by
guards in a prison, by security officers in an organization or
institution, or by employees in a large industrial complex (as an
industrial signaling device for safety). In areas that 1 person is
not allowed to work alone, MDT-122 can be an excellent solution.
MDT-122 and the recommended compatible receiver MCR-308
(or SCP-552 ER, PowerMax, Maestro-1600 or MAX-20W
wireless devices) can be integrated in any alarm system.
MDT-122 is attached to the guard’s pouch / holster.
The transmitter is activated in the following events (see fig. 2):
A. PANIC
When the guard needs help, he presses both buttons
(pressing both buttons is required to prevent an accidental
panic message transmission).
B. MANDOWN
When the guard falls down (automatic transmission when the
unit is tilted down by more than 60°).
C. PULL-CORD
The pull-cord is attached strongly by a clip to the guard’s belt
on one side and is plugged into the transmitter by an easily
detachable plastic pin on the other side. Pulling the cord or
the unit away causes the plastic pin to be detached and to
release an internal switch that activates an alarm
transmission. This may happen when an attacker tries to
draw the unit away from the guard or by the holder, in case of
emergency and difficulty to press the twin buttons for alarm.
D. TEST
When the guard presses the left or right push-button, a test
message is sent to the alarm system and the LED is lit.

Figure 3 - Activating the
Internal Tilt Switch
E. TAMPER EVENT
When the transmitter is opened by an unauthorized person.
When the transmitter is activated, an identifiable alert is
transmitted to the associated receiver. As a result, a siren
sounds, an automatic dialer calls predetermined addressees,
etc., as desired, to provide the required help.
Tilt alarm restoration message is transmitted when the unit
returns to its normal position (vertical) and when the tilt on/off
switch is switched to OFF position.
The transmitter is not activated during the guard’s regular daily
activities (running, jumping, sitting, bending, removing clothes,
going to bathroom and going off and on duty).
If the unit is laid down in horizontal position more than 60
seconds, while the tilt ON/OFF switch is in OFF position, when it
is returned to vertical position 3 beeps are sounded, to remind the
user to return the Tilt switch to ON position (Tilt switch reminder).

. FUNCTIONAL DESCRIPTION. FUNCTIONAL DESCRIPTION
. FUNCTIONAL DESCRIPTION
3.1 Visual and Audible Warning Timing
A built-in tilt sensor activates the unit when the unit is tilted down
by more than 60°(see figure 3). When the unit is activated, it
enters a pre-alarm state for 15 seconds. This period enables the
user to return the transmitter to the normal (vertical) position, to
prevent an unintentional alarm transmission.
During this period an audible warning is sounded by the buzzer
and a visual warning is indicated (by the internal LED). The
buzzer’s sound can be disabled by using an internal buzzer’s
switch (see table 1). Figure 4 presents the timing diagram.
Figure 4 - MDT-122 Functional Timing Diagram
3.2 Low Battery Voltage Indication
The battery is automatically tested every hour, under load
condition. If the battery voltage is low, “low battery” message is
sent every transmission and whenever supervision message is
sent (if enabled, see table 1).
In addition, when the battery voltage is low, the LED blinks while
pressing the left or right push-button switch.
3.3 External Buttons Functions (see fig. 2)
A. Left or Right push-buttons
When the guard presses left or right push-button, a test
message is sent to the alarm system or any other desired
auxiliary function is performed, according to the software
definitions.
When left and right push-buttons are pressed, panic alarm is
transmitted.
B. Tilt ON-OFF Slide Switch
By using this switch, the user can disable the tilt sensor
function (this is necessary when a guard goes off duty or
performs such activities that can activate the transmitter and
create a false alarm). When the unit is delivered from the
factory, the switch is in OFF position.
C. Temp Tilt Off Push-Button Switch
The push-button is located at the top of the unit. It is used for
temporary disabling (5 minutes) of the tilt sensor function,
when it is desired. To re-enable tilt function before the 5
minutes delay expires, the tilt ON-OFF slide switch should be
switched to OFF position and then to ON again.
3.4 Pull-Cord Function (see par. 1C)
3.5 Internal DIP Switches Functions
Table 1 - Internal DIP Switches Functions
Switch Description Default
1 Buzzer ON/OFF ON
2 Pull-cord option ON
3 Supervision ON/OFF OFF
4 Supervision message type (*) OFF (slow)
5 (For future use) -
6 Tilt alarm delay ON/OFF (**) ON
*Supervision Type
This switch should be left in OFF position. In this position the
supervision messages are transmitted every 60 minutes (slow
rate), to save battery power.
** Tilt Alarm Delay Enable/Disable
Fifteen second pre-alarm delay enabled/disabled.
If the “tilt alarm delay” DIP switch is set to OFF position (no
delay) the tilt pre-alarm DIP switch position is disregarded.
3.6 Buzzer Functions
The internal buzzer sounds, as shown in figure 4 and in the
following situations:
A. When someone is tampering / stops tampering with the unit.
B. Whenever the internal DIP switch setting is changed.

4.2 Teaching the Target Receiver
It is recommended to use the MDT-122 with MCR-308 as a target
receiver (for other receiver types, see section 1). Each of the four
MDT-122 alarm types (Panic, Man-Down, Pull-Cord, Test)
activates a different MCR-308 output, to provide any desired
function, like sounding a siren or activating an automatic dialer
(for delivering a prerecorded voice/digital message to
predetermined addresses).
To provide the desired alarms, the target receiver must “learn” to
identify the Man-down transmitter transmission. For the learning
process, refer to the relevant receiver installation instructions
document. If MCR-308 is used as a target receiver, refer to
document DE3191, paragraphs 3-5 and 3-7 to 3-9.
4.3 Test
Simulate all the actions that are shown in figure 4 and verify that
proper buzzer, LED and transmissions functions are performed.

. NOTES AND WARNINGS
5.1 Product Limitations
Visonic wireless systems are very reliable and are tested to high
standards. However, due to low transmitting power and limited
range (required by FCC and other regulating authorities), there
are some limitations to be considered:
A. Receivers may be blocked by radio signals occurring on or
near their operating frequencies, regardless of the digital
code used.
B. Wireless equipment should be tested regularly to determine
whether there are sources of interference and to protect
against faults.
5.2 Compliance with Standards
WARNING! Changes or modifications to this unit not expressly
approved by the party responsible for compliance could void the
user's authority to operate the equipment.
The 315MHz version complies with FCC Rules Part 15.
Operation is subject to two conditions: (1) This device may not
cause harmful interference, and (2) this device must accept any
interference that may be received or that may cause undesired
operation.
The product has been tested and found to comply with the limits
for class B digital device, pursuant to part 15 of the FCC Rules.
These limits are designed to provide reasonable protection
against harmful interference in a residential installation. This
equipment generates, uses and can radiate radio frequency
energy and, if not used in accordance with the instructions, may
cause harmful interference to radio communications. However,
there is no guarantee that the interference will not occur in a
particular installation
