23.19 ATS levels and attenuation specifications
ATS (Alarm Transmission System) Levels
The following table lists the ATS levels required for the panel when communicating
over:
GSM to Alarm Reporting Centre (ARC)
PSTN to Alarm Reporting Centre (ARC)
Ethernet to SPC Comm receiver software
GPRS to SPC Comm receiver software
Attenuation of PSTN
For a PSTN dialer, a CW1308 Internal Telecom or equivalent cable should be used
to connect the modem to the phone line. The cable length should be between 0.5 –
100m.
Attenuation of Ethernet
For Ethernet, a Cat 5 cable should be used with its length between 0.5 – 100m.
Attenuation of GSM
The field strength of the GSM signal needs to at least -95dB. Below this level the
modem will flag a low signal fault to the panel. This is handled in the same way as
other faults on the system.
Monitoring and watchdog of PSTN (SPCN110) and GSM (SPCN310)
A failure of the interface between the PSTN modem and the panel will be detected
after 30 seconds, after which an ATS fault will occur.
A failure of the interface between the GSM modem and the panel will be detected
after 30 seconds, after which an ATS fault will occur.
