NOTES CONCERNING EN50131-4 CERTIFICATION

Importantly, jumper C must be kept intact to allow the siren to sound in case of remote power blackout for
the compliance to EN50131-4. Cutting this jumper will cause loss of compliance.
The intermittent sound (control AL2) is an auxiliary signal (it must not be used for burglar and/or tamper
alarm indications).
Note:
The batteries are considered dangerous waste (E.W.C.
160601) and they must be given to an authorised waste
disposal.
