MCMAS5

1. GENERAL
EL.MO.’s MCMAS5 is the new conventional detectors input module for AS protocol analogic loop systems.
Born from the experience and from the studies of our R&D team, it can boast several strengths:
•
Easy to install.
Easier wirings thanks to the removable terminal board;
•
Compact.
Compatible with optional 503 flush mount box;
•
Versatile.
Can be powered up from an external power supply unit or directly from the loop;
•
Suitable for power group monitoring.
Where there is no dedicated serial line for monitoring power supply units directly from
a control unit, MCMAS5 can monitor the fault status of the PSU through a LED and by bouncing the alarm to the control unit.
Since the fault is signalled by lack of power on the fault line, any line interruption is treated as a fault as well.

Also see the Declaration of Conformity at the end of this manual, or download it from the www.elmospa.com website.
4. INSTALLATION
Install MCMAS5 on AS protocol loops only.
WARNING: in order to avoid false alarms or electronic components damage, make sure panel and
loop are disconnected from power during wiring, installation and maintenance operations.
4.1 Overview and wiring diagram
Wire as shown in pic. 1. Diagrams labeled b, c, d and e show tipical wiring examples for some different kind of commonly used
detectors: follow the wiring instructions on your detectors’ technical manual.
Detectors’ line needs a 3650 Ω end of line resistor (included) which is to be installed inside the casing of the last detector of the line.
For further data on how and when to wire supply line terminals, see section 4.4
