PPD Maintenance & Technical Manual
1.0 INTRODUCTION
The Senstar-Stellar personal protection device (PPD) is a body-worn radio transmitter, which
emits an alert signal when activated. The PPD is intended to be worn on the belt of the user.
When used in a facility equipped with the Senstar-Stellar Flash
transmitter notifies security staff an alarm transmission has occurred and reports the location of
the user on a computerized map of the facility (Flare ONLY). Each PPD is identified by a unique
ID code. The PPD is activated by pressing the red button on the front of the unit. The unit may
also be equipped with an optional 'man-down' module and/or a tamper detection lanyard.
The PPD is activated by pressing the red button on the front of the unit. Optional activation
methods include removing a lanyard/pull-pin assembly and an automatic “man-down” mode that
is initiated based on the tilt angle of the transmitter.
This manual contains operating instructions for the PPD unit, care and maintenance instructions,
as well as a detailed theory of operations.

2.0 OPERATIONS AND MAINTENANCE
2.1 Operating Instructions
2.1.1 Wearing the PPD
Always wear the PPD on the belt in a location that permits easy access to the push button or pullpin. It is recommended the unit be used with the optional carrying holster for added protection.
Insert the PPD into the pouch with the logo-end first taking care to line up the button with the
hole in the pouch. The significance of this is to avoid covering the antenna (mounted under the
logo) with your hand when reaching down to press the activation button. The performance of the
unit is not degraded if worn under clothing. If the unit is equipped with an external antenna, do
not wrap the antenna around the PPD – leave it hang vertically from the end of the PPD.
The leather holster is equipped with a loop over the top of the unit to secure the PPD. To remove
the PPD from the holster, unsnap the retaining loop and pull on the end of the PPD (in new
holsters, this pulling action may need to be accompanied by a push on the step of the housing
that is exposed in the push-button area). The holster is secured to the belt using an integral belt
loop. This loop is secured to the holster using polarized snaps. These snaps are polarized such
that they can only be removed by prying the snaps open with the fingers positioned under the
snap end of the belt loop. This takes a little practice. The purpose of the polarized snaps is to
prevent the unit from being pulled off the belt by force. To close the belt loop snaps, reverse the
motion used to open them.
2.1.2 Activation
The PPD is activated by pressing the red button on the outside of the unit. For optimum
reliability, feel for the raised centering dot on the button before pressing. The unit transmits a
unique ID code once each time the PPD is activated. It takes approximately one quarter (.25) of a
second for the transmitter to complete the alarm sequence once the unit is activated. The alarm
will be detected by the computer monitor within .5 seconds of activation.
Low Battery Detection (Automatic Activation)
The PPD continuously monitors its battery voltage. If the battery voltage drops below a predefined threshold, the unit automatically emits a low battery transmission to inform the head end
software that a particular ID transmitter has a low battery. [NOTE: This requires that your
facility has purchased the OPTIONAL low battery detection software.] The PPD is still capable
of transmitting ten times after reaching the low battery threshold. After the automatic low battery
transmission has occurred, the PPD will append a low battery transmission after each subsequent
alarm activation to remind the head end operator. Units in low battery mode should be taken out
of service. Battery replacement is a maintenance function.

PPD Maintenance & Technical Manual
Pull-Pin Option
Pull-pin version PPDs are activated by completely removing the pull-pin from its jack on the top
of the PPD. The pull-pin is equipped with a flexible lanyard to make activation easier. The
lanyard can be looped over a belt clip to force the PPD to alarm if it is ever removed from the
wearer. Re-inserting the pull-pin in does not prevent the transmitter from sending the alert signal.
Always return the pull-pin to its mating plug in the PPD housing so that the unit is armed and to
prevent the pull-pin from becoming lost. Do not cover the PPD with your hand when activating –
simply press the button or remove the pull-pin.
Man-Down Option
If the PPD is equipped with a man-down option, it will automatically activate if the unit remains
tilted too long. The default length of time of continuous tilt is 15 seconds. Consult the factory if
you wish to alter this time period – it can be programmed by the system administrator at your
facility. The default tilt angle threshold is 45 degrees. Consult the factory if you wish to alter this
tilt angle – it can be programmed by the system administrator at your facility. To help prevent
false alarms, the unit emits a warning tone once the 15 second timer begins counting. If the unit
is returned to vertical, the warning tone is silenced and the timer is reset. If the unit remains tilted
continuously for 15 seconds, the PPD will automatically activate an alarm transmission. The
default mode is to transmit one time only following a man-down condition. Consult the factory if
you wish the unit to continue to transmit – it can be programmed by the system administrator at
your facility.
2.1.3 Testing
Senstar-Stellar recommends staff test the PPD at the beginning of each shift. Your facility
administrator will develop a procedure for you to warn the security staff that a test transmission
is under way and for the security staff to communicate to you that the unit has passed. Follow
their established procedures. The battery is designed to support testing the basic PPD (no mandown option) three times per day for one year before battery replacement is required.
2.2 Do’s and Don’ts
DO
:
DO - Always wear the PPD on your belt.
DO - Always position the PPD on your belt such that the red button or pull-pin is accessible.
DO - When activating the alarm, feel for the bump in the center of the red button before pressing.
DO - Always wear the transmitter with the logo face facing away from your body.
DO - If your PPD fails to transmit upon activation, turn the unit into maintenance immediately.
DO - If you accidentally press the red button or remove the pull-pin, contact security
immediately to report the false alarm.
