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 FlashTM or FlareTM system, the 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).
PAGE 5
PPD Maintenance & Technical Manual 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.
PAGE 6
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.
PAGE 7
PPD Maintenance & Technical Manual DON’T Don’t - Submerge the PPD in water or expose it to pounding rain. Don’t - Cover the unit with your hand or metal objects while transmitting. Don’t - Wear or store the PPD without the pull-pin completely inserted. Don’t - Replace batteries unless you are a certified maintenance technician. Don’t - Remove the marking labels on the transmitter. Don’t - Drop or otherwise abuse the transmitter.

PPD Maintenance & Technical Manual 3.0 BATTERY SPECIFICATIONS AND REPLACEMENT 3.1 Battery Life Specification and Considerations DC Power Source +9V nominal battery Duracell, MN1604, Alkaline DC Current Consumption 110 mA +/- 20 mA (during full transmission) The end of life of the PPD is defined as the point at which the battery voltage drops to 7.0 VDC. At this voltage, the transmitter will still transmit reliably ten times at low temperatures.
PAGE 9
PPD Maintenance & Technical Manual C) Optional Features (Man-Down) The man-down feature reduces battery life due to the increased standby current drain and due to the fact that the unit will “wake up” every time it is tilted and start emitting tones. The number of times the unit is tilted is a variable beyond the manufacturer’s control, so a battery life specification is more difficult to define.

PPD Maintenance & Technical Manual Replacement of Battery Following Low Battery Detection: Serial Numbers Less Than 5599 If the battery is being replaced due to low battery detection, the PPD must be reset before returning it to operation. Before reconnecting the new battery, plug the PPD programming board into the programming connector slot within the battery compartment. Make sure the programming board jumper is in the position shown in Figure 3.2c.

PPD Maintenance & Technical Manual 4.1 Transmitter Specifications Model No: B76060 Supply Voltage 9 VDC (Duracell MN1604) Current Drain: 110 mA when active, 16 microamperes standby. Temperature -40 Deg C to +60 Deg C Operating Frequency Range 420-470 MHz Channel Resolution 6.25 kHz Output Power 17.0 dBm +/- 2 dB, measured into 50 Ohm Load Impedance 50 Ohm Modulation 2-FSK Average Deviation 2.
PAGE 15
PPD Maintenance & Technical Manual 4.2 Digital Modulation The digital modulation used in the Senstar-Stellar PPD unit is a tri-level 2-FSK format; i.e., the carrier frequency is part of the modulated waveform. The base band waveform is redrawn below for a sample ID word 366f (hex). Transmitted data waveforms are generated by the microcontroller (Atmel AT90S2313) and fed to the quad digital-to-analog converter (DAC - MAX533-pin 15).

PPD Maintenance & Technical Manual 4.3 RF Output This section details critical timing and power ramping waveforms. The waveform below indicates the RF power levels versus time from the initial alarm activation to the end of the transmission sequence.

PPD Maintenance & Technical Manual 4.4 PPD Detailed Hardware Description The following describes design goals for each of the functional unit elements in the PPD. This section provides typical performance characteristics of each unit element. These are not implied or guaranteed requirements and are intended for reference purposes only. 4.4.1 Synthesizer The PPD synthesizer covers the frequency range from 420 – 470 MHz in selectable channel increments of 6.25 KHz.
PAGE 18
PPD Maintenance & Technical Manual 4.4.2 Voltage Controlled Oscillator (VCO) The VCO was implemented using a Motorola MRF917 BJT in a Colpitts oscillator configuration. The design provides a tuning frequency range of 420 – 475 MHz. For interference and EMI reasons, the VCO and VCO buffer circuits are enclosed in a shield that clips to the PCB. The VCO varactor diode input is driven by the output of the PLL loop filter, setting the instantaneous transmitter frequency.
PAGE 19
PPD Maintenance & Technical Manual 4.4.5 Driver Stage The driver amplifier was implemented using a NEC/CEL NE85639. The driver amp has approximately 9-11 dB of gain at its output. The driver amplifier uses a software settable bias circuit. During the factory test, the microcontroller will set the bias level of the driver amplifier by varying the quad DAC output voltage accordingly (MAX 533-pin 2) while measuring the bias current and/or output power.
