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

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.

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.
