Class 1 Medical Device: Medical Gas Pipeline Systems
For more information & documentation please Contact us.
A 3-core data link connects the alarm to the end of line transmitter, regardless of the number of gases.
Simple modular maintenance:
Control PCB 230vac via Wieland ST18 plug & socket.
Control and transmitter boards designed with pluggable data terminations and signal inputs.
The alarm components can be changed in less than 2 minutes, remove fascia via 2 fixing screws and PCB via 3 further screws and unplug.
Several SAX-6 alarms can be connected to the same end of line components using just 3 cores.
The SAX-6 can transmit a common alarm, using the MEDCON data protocol, for display on the SDX-15 plant alarm system
The SAX-6 can also receive data from the SDX-15 Plant Alarm system.
The SAX-6 area alarm is used to monitor pipeline pressure within a ward, theatre etc. The pressure is monitored by pressure switches in the pipeline downstream from the last AVSU. Pressure is monitored for both high and low pressure (low only for vacuum). The integrity of the cabling between the pressure switches and the alarm panel is monitored, and a fault on this cable will result in a system fault alarm, with all affected alarm conditions going into alarm condition.
The monitoring of the cable requires a termination box to be mounted as close as practical to the pressure switches. As an optional extra, these termination boxes can be supplied with the cables for connection to the pressure switches already fitted, allowing significant savings in on-site work.
To use more than one SAX-6 alarm panel with one set of pressure switches, simply connect all SAX-6 alarm panels to the 3 core screened cable (minimum 0.5mm) from the termination box (either at the termination box itself, or at another SAX-6).
- SAX-6 has 3 LED indicators marked P, M & D on the front panel which indicate the following:
The P LED represents pressure switch inputs.
LED is off the panel has not been set up to detect pressure switch inputs via the end of line transmitter board.
LED is flashing, the SAX panel has been set up to receive pressure switch inputs, but has not been connected correctly to the end of line transmitter board.
LED is on, this indicates that the SAX panel and transmitter board are set up and communicating correctly.
- The M LED represents use with our MEDCON protocol (as with our SDX Plant Alarm System).
LED is off the panel has not been set up to work with our SDX system and NO plug-in upgrade card has been installed.
LED is flashing, then a plug-in card has been installed to enable use with our SDX system, but the 2-core data bus used for such systems has not been connected correctly.
LED is on, this indicates that the SAX panel is working in conjunction with the SDX network and is capable of transmitting the local alarm conditions onto the SDX system.
- The D LED is reserved for units with the main FPGA IC programmed to D type.
The LED is either on or off and is designed to show at a glance whether a unit incorporates the D type chip without having to open each unit up.
The purpose of the chip is to enable 2no panels (each 3 gas max) to provide status to 1no 6 gas central unit using standard boards and cabling.
A 230 vac supply, fused at 3 amps, fed from the essential supply
A 3 core screened cable (minimum 0.5mm) from the alarm panel to the termination board
All screens to be earthed at BOTH ends.
Warranty: alarms returned to our works which have failed due to faulty parts or manufacture will be repaired (or replaced) without charges for parts and labour.
10 year compatibility warranty: Install the SAX-6 with the confidence that equipment will be available to modify or extend the system for at least 10 years.
HTM0201 compliant (also BSEN 737 part 3 and BSEN 4754)
When ordering, please specify the following format:
SAX x y
x = number of gases
y = surface (s), flush (f) or flush deep (fd)
If possible, the hospital in which the alarm is to be installed.
