The Metro controller is capable of
monitoring up to 250 Metro remote
addressable gas detectors. Together they
form the Metro system designed to protect
people from flammable and toxic gas
hazards commonly found in car parks,
tunnels or other areas where automotive
vehicles may operate.

The Metro controller provides automatic control
of ventilation systems that maintain gas levels at
or below a safe level. Where gas levels rise above
maximum exposure limits the Metro system raises
alarms to instigate site evacuation. By integrating
the gas monitoring system and ventilation control
not only are harmful gases kept to safe levels but
building running costs are also minimised.
The system allows for two separate radial
circuits up to 1km (3000 feet) long using industry
standard cable. Each circuit provides power and
communications for up to 125 detectors.
Each system is able to monitor 250 toxic, 125
flammable or a mix of 80 toxic and 80 flammable
detectors. The AC system design ensures no
booster power supplies are required to achieve
long cable runs, greatly simplifying the system
specification, installation and operation.
Equipment installation and commissioning is kept
as simple as possible. A wall-mounting bracket is
provided to which the slim line controller is fitted.
All cables and conduits enter the lower side of the
controller via the pre-formed knockouts. Clearly
marked terminals ensure cabling connections are
rapidly completed.
Once the controller and detectors are installed
and powered up, the controller automatically
recognises which detectors are fitted. Adjustment
of detector settings can be made via an infrared
remote control unit as required.
With up to 250 addressable gas detectors
fitted to a system, each with 4 alarm levels, up
to 1000 alarm events can be detected by the
controller, all of which are logged for later review.
Grouping, voting and activation of up to eight fully
programmable relays can be set up via the
push-button interface or optional PC software.
Each relay can be configured for normally
energized/de-energized, latching/non-latching
and on/off delay operation. Manual override
switches for all relays are included as standard
in the controller. In addition system operation
may be forced remotely via a Remote Override
Box if required.
Easy to specify, install and operate, used as a
standalone gas monitoring system or as part of
a wider building management system, the Metro
gas detection system ensures people are kept safe
from gas hazards and building operating costs
are minimised.

General Specification
Use etro addressable gas detector control system for monitoring of flammable and toxic gas hazards commonly found where motor vehicles operate such as car parks,
M
tunnels or warehouses. Provides central monitoring of detector status, local annunciation and automatic control of ventilation and evacuation systems. Suitable for use as an indoor standalone solution or as part of a larger distributed control system
Operation
Display Ultra-cleardisplay with automatic backlight operation for dark environments. Details relay and detector status, first alarm indication with scrolling history of events, as well as providing alternate pages for review of relay output and fault histories
Other Indication
Ultra bright alarm and power LEDs
Response Time
All factory set alarms are instantaneous i.e. time weighted function is disabled. Instantaneous alarm response time 33 seconds (maximum). Time weighted alarms may be set from 1 minute to 8 hours. Alarms may be set between 10% and 90% of full scale
Audible Alarm 85dBA at 1m / 90dBA at 1 foot, user hush facility with re-activation on subsequent events. Can be permanently disabled for ‘silent’ operation
User Interface T hree level access for normal user, supervisor and service engineer. Normal user: Accept/reset of alarms or review of current events only
Supervisor (via key locked door): As above plus configuration/system interrogation using concealed pushbuttons
Service: As above with access to all terminal compartments via removable isolation plates
System Override Automatic/manual operation of all relays via manual override switches (service function) or via Remote Override Box
ZHC2 Infrared Remote Control Supplied with each system the ZHC2 allows convenient set up and configuration of all field devices. Field configured detector information is then downloaded
into controller to configure all inputs
Installation Details
Highlights
The Metro controller should be mounted with
the display at eye level using the mounting
bracket provided.
All cable entries are made from the bottom via
pre-formed M16/M20 and 3/4" NPT
knockouts as appropriate to the method of
cable installation.
The system electrical supply should be made via
a lockable fused isolator suitable for the overall
power requirements.
5 core, AC rated, 1mm2 (17AWG) minimum,
with overall screen should be used for
installation. Cable may be channelled though
conduit depending on site practice. Continuity of
the screen should be maintained throughout the
system for maximum resistance to RFI.
