Securitas America Inc. SBA-2000 Manuel D’Utilisation

A variety of equipment is used to make up an Angelwatch

 system. The equipment 

actually installed at a site will vary depending on the needs of that particular hospital.  

 

The Angelwatch

 system is based around a small computer running the system soft-

ware. This computer is called the Master Workstation (Model # MWS-1000) and all the 
receivers and Remote Workstations are connected to it. The computer uses Microsoft 
Windows 2000 as an operating system. In addition, the computer is equipped with an 
Uninterruptible Power Supply (Model # UPS-1000) to ensure that the system will 
continue to operate if power is interrupted. 

In addition to the Master Workstation, up to sixteen Remote Workstations (Model # 

RWS-1000) may be connected. The use of Remote Workstations allows use of the system 
and displays alarm conditions from several locations within the facility. 

 

The receivers are connected to the system using an RS-485 serial data network. This 

allows up to 255 receivers to be connected to the Master Workstation. There are three 
types of receivers available for use with the system. The  receivers are powered by 12 
volts DC from custom wall mounted enclosure(s) that contain an Un-interruptible Power 
Supply (UPS) and the necessary hardware engineered for that particular system  

The Internal Locating Receivers (Model # INR-1000) are used to monitor the 

presence and status of the anklets. The number of INR’s varies by site. The INR receiver 
will set an alarm if it loses the signal from the anklet and no other receiver has detected it, 
or the anklet is cut while being monitored. The lost band time is set to 60 seconds at the 
factory, however, this default time can be changed by personnel that have access to the 
Maintenance Commands menu. 

Exit Receivers (Model # EXR-1000) are used to monitor entrances and exits from the 

area in which the anklets are allowed. The Exit Receiver will only set an alarm when it 
detects an anklet within its coverage area indicating that a monitored infant is in an exit 
area. 

Locking receivers (also Model # EXR-1000) do not set an alarm on the system. This 

receiver has the ability to activate a door lock whenever it detects an anklet and is 
interfaced with magnetic door locks. 

There may be occasions where a hospital will want a receiver to do more than set an 

alarm. This is especially true of the Exit Receivers, where hospitals may want them to 
activate a security camera or tie to another security system. Angelwatch

 Receivers have 

a small low power internal relay (form C dry contacts) which is activated whenever an 
alarm is set. The Internal locating receivers (INR1000) activate for all alarms. Exit 
Receivers (EXR1000) activate when that particular exit is violated. 

 

 SmartBand Anklet 

The Angelwatch

 SmartBand Anklet (Model # SBA-1000) is the heart of the system. 

This anklet transmits a code to the receivers that is used to monitor the infant. Alarms are 
set when a band is lost, broken or detected by an Exit Receiver. The anklet is designed 
for a single use and is then discarded.
