1. INTRODUCTION
1. INTRODUCTION
1. INTRODUCTION1. 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.
The MDT-122 alarm signal can be received by a compatible
receiver, like MCR-308, and 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
(pressing both buttons is required to prevent an accidental
panic message transmission).
B. MANDOWN
When the guard falls down (automatic transmiss ion 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 si de. Pulling the cord or
the unit away causes the plastic pin to be detached and to

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.

3.1 Visual and Audible Warning Timing
A built-in tilt sens or activates the unit when the unit is tilted down
by more than 60
enters a pre-alarm state for 30 seconds. This period enables the
user to return the transmitter to t he 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.
MDT-122 is returned to
normal position after 30 sec.
(see figure 3). When the unit is activated, it

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 activiti es 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
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.

3.2 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.
In addition, when the battery voltage is low, the LED blinks while
pressing the left or right push-button switch.

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
three MDT-122 alarm types (Panic, Man-Down, Pull-Cord)
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 t ransmission. 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 act ions t hat are shown in figure 4 and veri fy that
proper buzzer, LED and transmissions functions are performed.
5.1 Product Limitations
ResponseLink wireless systems are very reli able and are tested
to high standards. However, due to low transmi tting power and
limited range (required by FCC and other regulating authorities),
there are some limitations to be considered:
Receivers may be blocked by radio signals occurring on or
A.
near their operating frequencies, regardless of the digital code
used.
Wireless equipment should be tested regularly to determine
B.
whether there are sources of interference and to protect
against faults.
5.2 Compliance with Standards
WARNING!
approved by the party responsible for compliance could void the
user's authority to operate the equipment.
Changes or modifications to this unit not expressly
The 433.92MHz 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 ac cept 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 cla ss B digi tal devic e, pursua nt 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
