When interconnecting 755PSMA2 smoke alarms and using the new 755RB base do all smoke alarms need to have the RB base to be tested remotely?


Only one 755RB base is required to test the interconnected smoke alarms. Hushing of smoke alarms in alarm state  can only be done remotely if the alarm that has triggered the event is the alarm with the 755RB base , If this is not the case then the alarms must be hushed manually from whichever 755 unit has caused the alarm initially.
This is to ensure that alarms are not Hushed remotely without full inspection of areas containing all interconnected smoke alarms which may be sounding due to a genuine issue but not seen from the remote location .

In regards to the METSEPM8000DEMOT , METSEPM8000DEMOK , METSEPM8240DEMO , METSEPM8244DEMO Is there any plan to add additional memory? If yes will it be expandable on the meters installed on the field?

The PM8000 will ship with 512MB of memory. The PM8000 is considered an Intermediate range meter versus the Nexus which would be an advanced range meter. The meter provides a slot for a field installable SD card memory, but is not functional in the first release. A future firmware update will enable this memory card slot providing support for up to 4GB of memory.

Can the new 755PSMA2 smoke alarms be connected to home automation systems, such as C-Bus?

Yes, by using the 755RB optional relay base. The relay base can be connected to an auxiliary input type device such as a C-Bus bus coupler so that when the relay in the smoke alarm base operates, it triggers the system according to its programming. The system may then be programmed to send push notifications to a smart device or to trigger an event like enabling exit lighting, or triggering an “all lights on” function. The remote test/hush input on the 755RB can be connected to a relay on a home automation system (e.g. C-Bus Relay), so that the system can test/hush the smoke alarm as well. 

Which type of switch should be used for the RemoteTest/Hush feature on the 755PSMA2 Smoke alarm?

Any 240V momentary switch, such as a 30MBP Bell Press Switch can be wired to either of the two new mounting bases 755RB or 755RFB up to 20m away. A relay can also be pulsed on momentarily via a security or home automation panel to activate the test/hush function. 

Can the Clipsal 755PFM have a remote switch fitted for test/Hush function?

Yes, but the optional mounting base 755RB (Mounting Base with Integrated 2A Relay and Remote Test/Hush Function ) or 755RFB (Mounting Base with Wireless Interconnect and Remote Test/Hush Function) must be added. The feature can be wired through any momentary switch. Once activated, normal operation resumes after about 10 minutes.

Is there a device that turns my lights on when my smoke alarm goes on?

Yes, if you have a 755PSMA2, you can use the 755RB Base which has a set of built in contacts or you can use a 756 Isolation unit which also carries out the same task.


Can the vertical cable management fingers for 600mm wide NetShelter cabinets be installed into 750mm wide NetShelter cabinets?

A customer may want to install the AR7721, AR7722 or AR7723 into a wide NetShelter SX or SV. 

Product Line: 
NetShelter SX and SV

All models, all serial numbers. 

The Compatibility Chart shows that these cable managers are not compatible with the wide SX or SV cabinets. 

They can certainly be installed into a 750mm wide cabinet. 
AR7721, AR7722 and AR7723 were originally designed for the 600mm wide NetShelter SX cabinets, so in the Compatibility Chart (FA158651) they are listed as compatible with the 600mm wide cabinets only. 
In the SX cabinets a better choice may be the AR7580A (42U), AR7585 (45U) or AR7588 (48U) because they offer far more capacity. 
In the SV cabinets AR7721 and AR7723 are currently the only finger-style vertical cable managers available.

Example of cascading MBP_MSTR in Concept IEC programming language.

Goals and Symptoms

Cascade MBP_MSTR

Causes and Fixes

Below is an example of how to cascade 3 MBP_MSTR's so that only 1 is active at a time. This concept can be expanded to any number of MSTR. Also a listing of the variable declarations is provided.

The first section is just a coil which signifies the first scan of the PLC. After that every 750ms the first MSTR will activate. The second MSTR will not activate until the first has completed or given an error. The final MSTR will activate based on the completion or error of the 2nd MSTR. Also all MSTR's are then reset based on the completion or error of the final MSTR. In the event of an error on an MSTR the error code is moved into a Register (MSTRx_Error_code) so that it can be seen even after the MSTR has been reset.

Can the horizontal cable troughs AR8008BLK and AR8016ABLK be used in conjunction with vertical cable managers AR7580A, AR7585 and AR7588?

We need to know if the tabs on the horizontal cable troughs will mount to the rails when vertical cable managers AR7580A, AR7585 or AR7588 are also installed. 

Product Line:
NetShelter SX Wide cabinets, vertical cable management and horizontal troughs. 

All 750mm wide NetShelter SX cabinets: AR7580A, AR7585, AR7588, AR8008BLK, AR8016ABLK; all serial numbers. 

A customer wants to use both vertical finger-style vertical cable managers and horizontal cable troughs on the mounting rails of a 750mm wide NetShelter SX cabinet. 


Yes, when using vertical cable managers such as AR7580A, AR7585 and AR7588 you can still install the cable troughs which run front to rear: AR8008BLK or AR8016ABLK. 

Additionally, you may also use the roof brush strips AR7714 (5 per pack) to close off the holes in the cable managers and prevent hot air recirculation. 
The finger-style cable managers are a 2-piece item, and both pieces are required to fully populate one vertical mounting rail in the cabinet. 
One set of AR7580A requires 6 roof brush strips. 
One set of AR7585 requires 6 roof brush strips. 
One set of AR7588 requires 6 roof brush strips. Note: the vertical mounting rails for 48U cabinets have 7 thru-holes but the AR7588 only has 6. The center thru-hole in the mounting rails is covered by the AR7588. 

Can the horizontal cable side channel organizer be installed into a 600mm wide NetShelter SX, VX or SV cabinet?

The AR8008BLK and AR8016ABLK are designed to install into the mounting rails of NetShelter SX 750mm wide cabinets. 

Product Line: 
NetShelter Cable Management

AR8008BLK and AR8016ABLK; all ranges and serial numbers. 

Customers need to move cables horizontally from front to rear in a 600mm wide NetShelter cabinet. 

Yes, the AR8008BLK and AR8016ABLK can be installed in the narrower 600mm wide NetShelter cabinets when paired with a cable manager like AR8603A. 
The AR8603A has two large brush-stripped sections that allow cables to feed through. Each of these areas has slots to support up to two of the cable side channels. (4 cable side channels total) 
When the AR8603A are installed in the same U-space in the front and rear of the cabinet cable side channels can run between them. 
Some customers installing the AR8603A in the front of the cabinet may notice that the cable manager will interfere with the door closing when the rails are in their forward most position. This issue can be overcome by installing the cable manager to the rear of the front rails so the cable fingers are facing inward.
