Annex D - Lps 1277 Conformance Statement - WebWayOne WebWay IP/GPRS Installation Manual

WebWay IP/GPRS & WebWay GPRS/PSTN Installation Manual
Annex D – Conformance statements relating to LPS 1277
Compliance with clause 7.2.1 of EN54-21
This installation and user documentation provides the general description of the equipment including the functions relating to the
relevant parts of EN54 and associated ancillary functions.
The product complies with CISPR A (Commercial) with any combination of interfaces fitted.
The product complies with CISPR B (Domestic) when either the PSTN ATS interface or the DCM is fitted.
Alarm transmission and acknowledgement times – EN54-21:2006
In order to comply with requirements of EN54-21 7.4.1 a hard wired fire alarm input must use pin 1 to ensure that in the event of
the fire alarm being triggered at the same time as any other event, the fire alarm will be transmitted first.
Where the WebWayOne SPT is installed in a separate enclosure to the fire alarm system and using a serial interface for the
transmission of the fire alarm and fire fault conditions, then the interface must operate in compliance with the requirements of
EN54-21 clause 5.3b4.
Availability classification
In all configurations the WebWay Alarm Transmission System will identify paths and ATS that do not meet availability classification
A4 as specified in EN 50136-1-1.
The WebWay Alarm Transmission System provides management information systems so that ATS's not meeting the necessary
performance levels can be identified and steps taken to resolve the causes. WebWayOne issues regular reports for Alarm
Companies to maximise the availability of al ATP and ATS
Fault detection and reporting - General
The WebWay IP/GPRS and GPRS/PSTN shall detect all appropriate fault conditions within the times specified in EN 50136-2-1.
These include failure of the interconnection between the SPT and the CIE. Typically fault conditions are detected in less than 10
seconds and reported within the normal alarm transmission times.
Input and output signal requirements
The specification of the various inputs and outputs to the WebWay SPT are as follows:
Ethernet interface – in compliance with the relevant industry standards for a 10BaseT Ethernet interface
GSM/GPRS interface – in compliance with the statutory requirements for this type of interface.
Serial panel interface – RS232 configuration – compliant with the electrical specification for this type of interface (RS232 –
V24/V28) at the data rate for the panel configuration used.
Serial panel interface – RS485 configuration - compliant with the electrical specification for this type of interface (RS485/RS422) at
the data rate for the panel configuration used.
Serial panel interface – TTL configuration – compliant with a TTL type interface running on a 3.3V supply rail but tolerant to 5.0V
logic levels.
Hardwired outputs – open collector outputs requiring an external pull up load. Maximum current sink per output is 30mA. Maximum
voltage, output terminal to ground is 30VDC.
Hardwired inputs 1 to 8 – In 'End of Line' mode the inputs will detect and report open circuit, short circuit, alarm and restore states.
Hardwired inputs 9 to 16 -
Open circuit loop >100k
Short circuit loop <5R
Alarm state 10k +/-5%
Restore state 14k7 +/-5%
Tamper 5R < loop < 10k-5%
10k+5% < loop < 14k7-5%
14k7+5% < loop < 100k
Hardwired inputs 8 to 16 – Maximum input voltage is 30VDC. Input threshold high to low is 2.0VDC. Input threshold low to high is
4.0VDC.
Tamper, battery fail and mains fail inputs – same as for hardwired inputs.
