MP500/4N-8-16 Installation
5.7 INSTALLATION OF THE EP508 EXPANSION
In addition to inside the control panel, the EP508 expansion can also be installed inside a CP/EXP container (certified Grade 3) or a
CP/EP500 container (not certified).
IMPORTANT! the absence of a casing certified Grade 2 or 3 results in the loss of certification.
The tamper of the container must be connected to the SAB of the expansion.
The expansion has terminals for connecting the power supply, detectors, ad signalling devices, etc.
The electric outputs can be transformed into relay outputs – See Paragraph 5.12.6.2.
