MSA Brand Module Model Fm002A Facilities

Description

The FM002A is a Facilities Module which provides a range of common facilities for all Zero Two Control Modules housed in the Chassis.

The FM002A is plugged into the last slot on the right hand side of a 4, 8 or 16 Channel Chassis.

Chassis may be daisy-chained whereby one FM002A will serve up to 100 Zero Two Modules of any combination.

Common Alarm Outputs for A1, A2, Fault and UA (Unaccepted alarm)

A Master Reset pushbutton, which resets any latched alarm condition which is no longer valid.

An Accept pushbutton which acknowledges

alarms by de-activating the UA outputs and causing the alarm logic outputs and indicators to revert to a steady ‘ON’.

The FM002A can be supplied with or without alarm relays.

A typical sequence of action would be:

If any Control Module in the Chassis goes into an A1 alarm, then a signal will be bussed to the FM002A,

activating the A1 alarm and UA outputs (open collector and relays).

If the ACCEPT button is pressed, the UA outputs will be de-activated both on the Zero Two Module and the FM002A.

Should the Module go into an A2 Alarm, then a further signal will be sent to the FM002A which will activate the A2 outputs and re-activate the UA.

Pressing the ACCEPT button will again de-activate the UA outputs.

Any subsequent alarms from the Modules will have the same effect in re-activating the pre-accepted UA outputs.

Pressing the MASTER RESET button will de-activate any latched alarms, provided that the gas concentration is lower than the alarm set point,

or in the case of a Fire Signal, if these are no longer activated.

Pressing the MASTER RESET button for a period greater than three seconds will illuminate all displays and LED’s on the Modules in the Chassis.
