Recommendations for the recording of remotely notified alarm conditions (BS 8243:2010 - Annex G.1 and G.2)
Alarm conditions can be categorised for analysis in accordance with Annex G if the SPC system is configured so that the entry timer is less than 30 seconds, and the dialer delay is set to 30 seconds.
See the following sections:
Requirements for systems using dedicated alarm paths (BS EN 50136-1-2, 1998)
The SPC system should be configured to do an automated test call to the ARC.
The SPC system should be configured with a 'Fail to Communicate‘ output.
See the following section:
Requirements for equipment used in systems with digital communicators using PSTN (BS EN 50136-2-2, 1998)
Fault Output
The SPC system should be configured with a 'Fail to Communicate‘ output.
See the following sections:
Retransmission Attempts
Retransmission attempts (Dial Attempts) are configured in this manual:
A minimum of 1 and a maximum of 12 retransmissions are allowed.
Intrusion and hold-up - System design (DD CLC TS 50131-7, 2008)
Setting and unsetting
SPC system is configurable in such a way that the setting is completed by 'Final Exit'.
It is possible to configure the SPC so that a WD (Warning Device) is activated momentarily on setting.
See the following sections:
Intrusion and confirmed hold-up alarm (BS8243:2010 Designation of hold-up alarm (HUA) signals for sequential confirmation)
SPC system is configurable in such a way that the following scenarios, when triggered more than two minutes apart from any hold-up zone or hold-up device (HD), will report a confirmed hold-up alarm event (HV for SIA and 129 for CID) to the CIE:
If a hold-up zone and a tamper zone or a panic zone and a tamper zone activation occurs within the two minute period, this will also send a confirmed hold-up alarm event.
A confirmed hold-up will not require an engineer restore even if engineer restore is enabled. A confirmed hold-up event is logged in the system log.
