The DM520 is used to interface a single zone of
conventional detectors onto the MINERVA
analogue addressable loop. This provides a cost
effective and easy method of extending existing
conventional systems or a future upgrade path for
new conventional systems. The DM520 is also
fitted with a red LED to indicate locally when the
associated conventional zone has entered an
alarm condition. The DM520 requires a separate
24V d.c. supply to operate. The module is
addressable and will therefore take one address
on the loop.
Technical Specification
Powered: 24V d.c.
Temperature Range: -10°C to 70°C
Operating Humidity: up to 95% RH non-
condensing

DM520 - Conventional Detector Module
The MDM521 module is used to interface
conventional detection zones onto the MINERVA
analogue addressable loop in a similar way to the
DM520. The MDM521, however, can be
configured to interface up to 8 zones of
conventional detectors rather than the DM520's
single zone. The module has an LED for each of
the 8 zones which will show red when the zone is
in alarm and yellow if the zone is in fault. This
module provides a cost effective method of
interfacing several conventional zones onto an
addressable loop.
The MDM521 requires a separate 24Vd.c. supply
to operate. The module is addressable and will
take as many addresses as there are zones being
monitored (i.e. between 1 and 8).

module
MDM521 - Multi-DM Module
The SM520 module is used to provide an output
to alarm sounders or visual warning devices in
response to a control signal from the control
panel. The devices are controlled directly from the
SM520 on the addressable loop rather than from
outputs on the control panel, thereby significantly
reducing wiring costs. The output wiring to the
alarm devices is fully monitored and the module
has the capability to drive up to a maximum of
500mA alarm device load. If higher alarm device
loads are required then an SB520 sounder
booster module must be used in conjunction with
the SM520. The SM520 requires a separate
24Vd.c. supply to operate. The module is
addressable and will therefore take one address
on the loop.

SM520 - Sounder Driver Module
The SB520 sounder booster module is used in
conjunction with the standard SM520 to drive one
or more alarm sounder devices from the
addressable loop rather than directly from control
panel outputs. The SB520 is required when the
alarm sounder load to be driven from the SM520
is greater than 500mA. Using the SB520
increases the sounder load capacity to 15A.
The SB520 requires a separate 24Vd.c. supply to
operate. The module is not addressable and will
therefore not take an address on the loop.

SB520 - Sounder Booster Module
The LPS520 module provides control outputs for
alarm sounders in the same way as the SM520
module, except that no external power supply is
required as the sounders draw their power
directly from the addressable loop. A maximum of
4 LPS520 modules can be used per loop, each
driving a maximum of 6 Banshee sounders.
The LPS520 takes its operating power from the
MINERVA loop.
The module is addressable and will therefore take
one address on the loop.
