A small number of recently manufactured I2000 Emergency Control Panels have suffered a momentary processor failure, rebooted, stopped working altogether or might have caused unwanted faults. The affected ECP boards are identified as being manufactured between April 2007 (date code D07) and September 2009 (date code I09) inclusive.
System Sensor has identified a potential issue with the Notifier FDMR-1 – Dual Input, Dual Output Modules, whereby a manufacturing defect may cause output relays to either fail to activate or fail to de-activate.
A minor issue has been identified with systems running Acclimate and SMART 4 multi-criteria detectors in CLIP mode, whereby multi-criteria devices programmed as sensitivity level 9 will still respond to alarm signals from smoke and heat as per sensitivity level 8, and are therefore unable to enter ‘heat-only’ mode.
NOTIFIER has released BacNet Gateway v3.24 firmware.
This update addresses an issue whereby Noti-Fire-Net performance may be unexpectedly slow during a de-isolate event from an AFP-2800 Fire Alarm Control Panel. It is recommended that all BacNet gateways installed on AFP-2800 networks use v3.24 for best system performance.
Apotential issue when ABS plastic solid Tees are bonded to ASD PVC pipe using traditional PVC solvent (cement).
Solvents are formulated for the type of plastic used to manufacture the pipe, therefore using a PVC solvent to bond PVC pipe and ABS plastic solid Tees may not create a reliable seal, the problem is amplified in refrigerated applications where the colder temperatures are present.
Recommendations for this type of bonding are to:
SYSTEM SENSOR has identified a technical issue with model 2151BAUS conventional photoelectric detectors manufactured in December 2012 that has resulted in the failure of the detector’s optical sensor in a small percentage of devices. A failure of the optical sensor will be indicated at the device as a chamber / maintenance fault, which is presented to the user by the LEDs on the detector no longer flashing.
