The green NORMAL status bar is a steady light, which
changes to a red flashing bar during HIGH and LOW
PRESSURE faults to draw attention to the failure.
Pressure fault conditions are accompanied by a two
tone audible warning. See table 6.
The audible warning continues until either the MUTE
switch is operated or the gas pressure returns to
NORMAL. If the MUTE facility is operated and the alarm
condition remains, the audible warning will re-sound
after 15 mins and a further MUTE selection will be
required. Should a further alarm condition occur after
the panel has indicated a fault and has been muted, the
audible warning is re-Activated.
Operation of the TEST switch changes all status bars to
flashing and sounds the audible two tone warning.
When the slave relay connection is interconnected to
either a Medipoint Digital central alarm system or other
suitable system, the contacts are closed when all gas
services are indicating NORMAL. In the event of any
alarm condition, the relay contacts open, breaking the
circuit to the remote system. The relay contacts remain
open until all alarm conditions return to the NORMAL
status. There is also a line contact monitor integral to
the board available across the N/O and C contacts. This
function is selected within the on screen setup menus
see section 3.
The green POWER ON LED is normally illuminated and is
extinguished in the event of an electrical power failure.
The red SYSTEM ALARM LED is normally extinguished and
illuminates flashing together with an audible warning in
the event of any of the following failures:-
• Alarm contact line fault.
• Electrical power supply failure.
• Internal alarm circuit failure.
When a line contact fault is detected, the NORMAL
status bar changes to red (steady). The SYSTEM ALARM
LED illuminates (flashing) accompanied by an audible
warning.
Operation of the TEST switch changes all gas status bars
to Red (flashing). If there is a faulty sensor or wiring
present the flashing rate will be at half speed. This
facility is designed to aid fault diagnosis. The Medipoint
125 medical gas alarm logic is detailed in Table 6.
