Man-Down Transmitter
1 1 1 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
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.

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
alarm
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).
