Personal Alarm System for Emergency Response
PAS is an ultrasonic emergency notification/communication system. The location of an individual moving throughout a facility is immediately determined when he or she activates their Personal Alarm Transmitter (PAT) device. Through integration with an overall security management system, the location of the individual requiring assistance can be graphically represented on a map-type display at a central location.
How It Works
One or more receivers are installed in each room or hallway that the system is required to cover. Upon activation, the transmitter carried by an individual emits a continuous ultrasonic signal. Receivers will only alarm when they receive a transmission containing specific frequencies in an established pattern. This eliminates false alarms from items such as keys, metallic items, and HVAC systems. The signal is Omni-directional, eliminating the need to point or direct the transmission.

Immediate Detection and Location
Accurate location identification
Timely response to an individual in distress
Audio output for assessment purpose
Flexible Activation Options
Push button activated
Pull pin activated
Pull ring activated
Man-down option available
PAS transmitters are discreet, compact and rugged and can be worn on the belt either with a belt clip or in a holster, or as a pendant. Transmitters can be activated by button press, pull-pin, pendant pull-ring or self-activated in a man-down situation. Receivers are flush-mounted in the wall or ceiling and provide an alarm output, auxiliary alarm output and a visible LED that illuminates when an alarm is received
The PAS receiver decodes the modulated ultrasonic signal emitted by the PAT. An alarm contact, auxiliary contact and LED activate each time an alarm is received and remain latched when an activated transmitter is within range. The receiving range is factory adjusted for a nominal distance of 15 m (50 ft) radial, 30 m (100 ft) diameter, and can be field-adjusted as required.
The PAT is activated by pushing a latching alarm button which has been specifically designed to prevent accidental activation. Additional methods are available as options, including pendant pull ring, pull-pin and “man down” (“man down” provides automatic transmission whenever an individual is in a prone position for a period of time). A breakaway lanyard is supplied with the PAT/C (compact unit) while sturdy pocket/belt clips enable a variety of carrying positions.
PAT Test Unit
The PAT test unit allows customers to regularly test the PAT units and maintain confidence in the operation of the system.
