1PoE (Power over Ethernet) does not provide EN 54-16 compliance.
2Microphones with more zone selection buttons: additional 55 mA per MPX10 10-button Expansion Module.
Maximum current consumption with fault sounder level set to 50%. Additional 40 mA if fault sounder is set to maximum level.
3Fault acceptance and clearance only available in emergency mode.
4Special variants are available to order, with more zone selection buttons; see ordering code on page 4.
5ASL PA/VA systems (refer to ASL for connectivity and software compatibility details): VAR4/12/20, VAR8, VAR8-ACU, VIPEDIA-12, iPAM400, iPA400,
VIPET, other VIPA devices.
6ASL protocols supported on the serial connection: ASL Serial, Paging (DMS) and Console (ACU). The protocol is defined by the host, and the MPS will
automatically discover the protocol upon connection.
7Hardware bypass is only provided on inputs 1 and 2 of ASL Voice Alarm Routers.
8IP interface does not provide EN 54-16, ISO 7240-16 or BS 5839-8 compliance at the time of publication of this Installation Guide. Note that Ethernet
connectivity is enabled for the IP variant with an additional IP licence.
9ASL protocols supported over IP: ASL Serial, TRL (Transactionless) and Paging (DMS). The protocol is defined by the host (if any), and the MPS will
automatically discover the protocol upon connection.
