ManDown Sensor

1. Introduction

The ManDown Sensor has a built-in tilt device, which can detect if the person holding it is in
a horizontal position, such as lying on the floor.
The sensor will automatically send an alarm when its position corresponds to horizontality
after a certain time. Pressing its central bed button will activate a help call at any time.
It can be held, for instance, as a necklace by an elderly person or as a safety device by a
lone worker in a hazardous environment.
The ManDown Sensor will be part of a social alarm system. It can be associated with a
Carephone receiver, linked to a social alarm call center through the telephone line, or with a
NurseCall system.

2. Description

The ManDown Sensor can be delivered with an operational frequency of 434 MHz or 869
MHz. It is equipped with a LED indicator that will flash every ten seconds to show that the
sensor is active. This LED indicator will flash green if the battery is ok or red if the battery is
low. Pushing the central red button will send a help call to the social alarm system, followed
by a short beeping sound.
Caution!
A help call is sent only after the central red button has been released. The user should be
aware that pressing the central red button must be short. If the central red button is being
pressed longer that five seconds, the sensor will be turned off, and no help call will be sent.
See chapter 4.2. Turning off the sensor.
