Masthead Relay Unit
LGMRU4x4
The masthead relay unit does everything
that a masthead unit can do but also
provides 4 alarm and tamper relay outputs.
This model is primarily intended to connect
directly to a dome camera’s pre-set inputs
but may also be used to connect to DVR’s
and alarm systems where a smaller number
of relay outputs are required.
A switch change converts the product to an
8 alarm output without tampers if required.
Expansion cards are available to increase
the number of alarm outputs up to a
maximum of 32.
