Wireless communications for monitoring
alarms
Acscom and Clarion Communications have made it possible to monitor alarm events and send the different levels of risk information to a remote receiver
The installation and operation of effective fire detection and alarm systems is now very much a standard basic requirement in every type of building However, for the disabled and hearing impaired the benefits of such technology have not always been fully accessible

Unmatched power for a PC based maths package, yet an even friendlier user interface: the latest version of Maple looks set to be enthusiastically received.
Now, Pacscom and Clarion Communications have, by using the benefits of wireless communications, made it possible to monitor alarm events and send the different levels of risk information to a remote receiver, such as a vibrating pager, carried by an individual.
This technology is particularly applicable to accommodation facilities such as bedrooms in residential premises for the elderly, university halls of residence and hotels.
Clarion Communications has been at the forefront in the development of wireless systems that comply with the third stage of the Disability Discrimination Act.

BS5839-1:2002, and has accomplished its objectives by using wireless communications technology developed by Pacscom Limited.
Clarion Communications' LifeLine system, which comprises two fire alarm panels and two types of vibrating pager, uses Pacscom's CPT family of RF paging transmitters and CSP 450 RF pager receivers for transmitting and receiving messages.
Pacscoms CPT pager transmitters and CSP450 receivers are low cost modules that have been specifically designed to be installed in OEM products.
These units are self-contained and are fully programmable through a serial port.
User interfaces are RS232, TTL level data or direct audio if modem functions are not required.
Like all Pacscom equipment, these units are approved for use throughout Europe.
The Pacscom CPT is a high performance POCSAG pager transmitter with an RF Power of up to 5 Watt (2Watt UK).
Providing a choice of serial interface or 4 Volt free triggers for fixed messaging, the unit can be configured to any frequency in the UHF frequency 406-475MHz band.
Reflecting the need for guaranteed radio performance checking, the CPT offers a power monitoring feature.
This monitors the transmitted RF power level measured at the final output stage of the transmitter and presents this as a voltage reading on two pins of the standard connector.
Positive feedback confirms that good RF is being transmitted by the unit and, assuming no physical damage to a properly installed antenna, gives a guarantee of the RF power being transmitted.
The Pacscom CSP 450 is a low cost receiver designed for serial data and is available for both VHF and UHF paging networks.
The unit provides Alpha/Numeric serial text data output to displays and up to four TTL switched outputs under message control.
In addition, via an intermediate module high performance switching of quite high currents can be accommodated.
The LifeLine unit is designed to comply with BS5839-1:2002, and provides a single panel interface to the fire alarm panel.
This robust system containing a Pacscom CPT transmitter in a wall-mounted enclosure is factory pre-configured for each customer and as such there are no user interfaces or configurations.
When the main building fire alarm is activated, the failsafe relay contacts alert the Pacscom transmitter to the alarm status and in turn, it alerts either the CSP receivers or the vibrating pager(s).
The system simply sends out pre-defined alarm messages to the vibrating pager, wall mounted display or both upon activation of the fire alarm and continues to alert the vibrating pager or display until the main fire panel is reset.
