An extensive range of ancillary modules has been
specifically designed for use with the MINERVA 8,
16E and 80 range of Fire Control Panels. The
M520 range of ancillary modules provide the
MINERVA Panel with a wide degree of systems
application flexibility. This allows the field
addressable loop from the control panel to both
receive inputs to the system and control outputs
from it.
This broad range of modules allows the scope of
the fire detection system to be significantly
extended beyond a simple fire detector - alarm
sounder based alarm system. The command
modules enable fire doors to be closed, fire
dampers to be controlled, provide an interface to
shut down HVAC equipment. Other applications
include an interface between shopping centre
tenants' premises and the landlords' central
control system.
With the high systems integrity offered on the
MINERVA Panel the command modules can also
be used to control a public address based
building evacuation system.
Features
• Communications and control interface to
MINERVA Fire Panels
• High Systems Integrity
• Allows remote sounder circuits
• Allows loop powering of sounders and/or
beam detector units
• Monitoring of external equipment, e.g. smoke
dampers
• Reduced installation cost
• Removes the need for separate plant control
circuits

The LI520 Mk2 line isolator is used to ensure that
a short circuit fault on the addressable loop will
not cause a total systems failure. LI520 Mk2's
effectively contain the fault to specific areas of the
loop. Line isolators should be used at the
boundary of each zone so that no more than a
single zone is made inoperative during a short
circuit condition. This feature is a requirement of
BS5839 Part 1 1988. The LI520 Mk2 is also fitted
with a amber LED to indicate locally when the
isolator has been tripped.
The maximum number of line isolators per
MINERVA loop is 12. There are also two isolator
circuits built into the MINERVA control panel loop
drivers (one for each end of the loop).
The LI520 Mk2 takes its operating power from the
MINERVA loop.
The module is not addressable and will therefore
not take an address on the loop.

The CM520 module provides the facility to
monitor an external contact, e.g. fire door monitor.
This monitored point can then be used as a
control input for the MINERVA panel which is
activated when the monitored contact is either
open or closed. A delay between the monitored
contact opening/closing and the activation of the
control input can be specified within the control
panel settings. The CM520 takes its operating
power from the MINERVA loop. The module is
addressable and will therefore take one address
on the loop.

The TM520 provides an output that can be
activated based on a delay time. If either the key-
switch on the module is activated, or a predefined
event within the control panel occurs then a timed
delay (set between 10 minutes and 21 hours 10
minutes) is started. When the delay reaches zero
the TM520 output is activated. The unit sounds an
internal buzzer and shows a red LED when the
output is active, and shows a yellow LED when
the timer is counting down. To provide a warning
that the delay is nearly over, the red LED and the
buzzer will pulse 5 minutes before the end of the
delay .
The TM520 requires a separate 24Vd.c. supply to
operate. The module is not addressable and will
therefore not take an address on the loop.

The RM520 provides one volt-free change-over
relay contact rated at 1A @ 24Vd.c. Command
signals to drive the relay are configured in the
MINERVA control panel software with the trigger
point being defined as a detector or other event
programmed into the system. The relay contacts
are monitored and the state (activated/de-
activated) is reported back to the control panel.
The RM520 is also fitted with a red LED to
indicate locally when the relay is operated.
Typical applications for the RM520 include fire
door control or lift control. The RM520 takes its
operating power from the MINERVA loop. The
module is addressable and will therefore take one
address on the loop.
