Wireless Devices Lock Out

DESCRIPTION

All wireless devices are locked out for extended periods of time on a SmartLine system. Transmit LED on Extended Receiver board(s) stay on.

NOTE: The SmartLine Master Interface receiver does not lock out devices and polling between the SmartLine Master Interface and the monitoring software continues as normal. Calls received by the SmartLine Master Interface will operate normally

CAUSE

A high level of noise induced on the extended receiver bus occasionally prevents calls from wireless devices from being acknowledged by the SmartLine Master Interface. As a result the Extended Receiver boards lock out devices while the system is waiting for a response.

RESOLUTION

An upgrade to the SmartLine Extended Receiver boards preventing the lock out from occurring is available to resolve this issue. Contact SmartLink regarding replacements of the SmartLine Extended Receiver boards.

To temporarily un-lock the system, activate a programmed wireless device within range of the SmartLine Master Interface receiver. This will cause the entire bus to reset (including any locked out Extended Receiver boards).

NOTE: Replacing the Extended Receiver boards or resetting the system will not cause any programming options to be lost.

Master Interface Does Not Recognise Universal Pendants

DESCRIPTION

Universal Wireless Pendants can not be programmed into the SmartLine System and/or don't generate alarms on SmartLine when activated, even though other wireless devices are recognised correctly.

CAUSE

SmartLink's range of Universal Wireless Pendants use 56-bit coding where as the previous range of devices use 40-bit coding. The Master Interface receiver component of the board developed in September 2002 is only compatible with 40-bit SmartLink devices.

NOTE: Consult the Master Interface PCB (Printed Circuit Board) for confirmation on the development date.

RESOLUTION

The latest SmartLine Extended Receiver boards can be interfaced with the SmartLine Master and are compatible with both the 56-bit and 40-bit wireless device range. Program the Universal Pendants via the Extended Receiver(s). Locate an Extended Receiver in close vicinity to the Master Interface to ensure all devices are recognised as the master receiver cannot process any new 56 bit coded devices.

Master Will Not Communicate to Computer

DESCRIPTION

Communication cannot be established between the computer (running Monitoring software) and the SmartLine Master unit.

CAUSE

A variety of problem might exist that can result in a loss of communications between the SmartLine master unit and the computer. The most common are the use of incorrect communication cables and the lack of a proper power supply.

RESOLUTION

Ensure correct power is present and a Null Modem cable is used and has not inadvertently been changed for a normal computer cable.

Receivers Not Working Properly

DESCRIPTION

Receivers are not functioning properly.

CAUSE

Correct power not supplied to receivers. System behaviour is not predictable.

RESOLUTION

Ensure that full power is available at the receivers and that the 0V of power to the master is bridged to 0V of the receivers, bypassing bridge rectifier.

Master Sometimes Not Receiving Reed Switches Closing Messages

DESCRIPTION

The master unit sometimes does not receive the reed closing messages.

CAUSE

Door opening and closing too quickly to handle 700ms lockout on same signal rejection software inside master.

RESOLUTION

Reprogram reed switch for at least 1 sec delay between open/close signals being sent.
