38 fault records for this panel, each labelled with its review status and, where one is cited, the source document it comes from. Protec Algo-Tec 6500 analogue addressable fire alarm control panel.
The "Alarm Fault" LED on the 6500 panel's indicator strip. This is one of the labelled LED indicators on the 6500 control panel's front fascia, confirmed directly from Protec's own product photography. The brochure documents that this indicator exists and its exact label, but — being a sales brochure, not an installation or commissioning manual — it does not describe the underlying cause, the specific conditions that trigger it, or the clearing procedure. Those details require the panel's installation/commissioning manual, which sits behind Protec's Client Support Portal login and was not accessed for this entry.
The "Alarm Routing Fault" LED on the 6500 panel's indicator strip, covering the alarm signalling/routing path (e.g. to an ARC or monitoring centre). This is one of the labelled LED indicators on the 6500 control panel's front fascia, confirmed directly from Protec's own product photography. The brochure documents that this indicator exists and its exact label, but — being a sales brochure, not an installation or commissioning manual — it does not describe the underlying cause, the specific conditions that trigger it, or the clearing procedure. Those details require the panel's installation/commissioning manual, which sits behind Protec's Client Support Portal login and was not accessed for this entry.
The "Aux Supply Fault" LED on the 6500 panel's indicator strip, covering the panel's auxiliary power supply. This is one of the labelled LED indicators on the 6500 control panel's front fascia, confirmed directly from Protec's own product photography. The brochure documents that this indicator exists and its exact label, but — being a sales brochure, not an installation or commissioning manual — it does not describe the underlying cause, the specific conditions that trigger it, or the clearing procedure. Those details require the panel's installation/commissioning manual, which sits behind Protec's Client Support Portal login and was not accessed for this entry.
The "Fire Protection Fault" LED on the 6500 panel's indicator strip, covering fire protection outputs (e.g. suppression or protection-related outputs) configured on the system. This is one of the labelled LED indicators on the 6500 control panel's front fascia, confirmed directly from Protec's own product photography. The brochure documents that this indicator exists and its exact label, but — being a sales brochure, not an installation or commissioning manual — it does not describe the underlying cause, the specific conditions that trigger it, or the clearing procedure. Those details require the panel's installation/commissioning manual, which sits behind Protec's Client Support Portal login and was not accessed for this entry.
There is a low resistance between loop '+' and loop '-'. The fault threshold is 200Ω (Issue E) or 120Ω (Issue F). This fault can also occur if more than ten loop device repeater LEDs are turned on at the same time.
The loop driver processor has reported a fault. Take the reporting panel offline then back online to attempt to clear it; if it persists, report the fault to Protec technical support.
There is a high resistance in the loop wiring. The fault threshold is 80Ω (Issue E) or 50Ω (Issue F), though the manual adds that "any value greater than 32 is considered high" (no unit given). The loop current calculator in the commissioning software should be used to confirm the system is designed correctly.
The loop has a short in its wiring — most likely in the wiring between loop side 'A' and the first device with an isolator, or between loop side 'B' and the last device with an isolator.
Two master panels have been detected on the network — either two panels were assigned as master in their configuration data (correct via the PC commissioning software), or a double break in the network wiring left two panels acting as master and one has failed to relinquish control on restoration (re-initialise the network at the original master panel).
The network has initialised with two panels sharing the same number; correct this using the PC commissioning software. Neither panel is allowed to transmit an event, so each will eventually also display a Slave CTS fault.
The "Network Fault" LED on the 6500 panel's indicator strip, covering the panel-to-panel network connection used when multiple 6500 panels are networked together. This is one of the labelled LED indicators on the 6500 control panel's front fascia, confirmed directly from Protec's own product photography. The brochure documents that this indicator exists and its exact label, but — being a sales brochure, not an installation or commissioning manual — it does not describe the underlying cause, the specific conditions that trigger it, or the clearing procedure. Those details require the panel's installation/commissioning manual, which sits behind Protec's Client Support Portal login and was not accessed for this entry.
The "Power Fault" LED on the 6500 panel's indicator strip, covering the panel's own power supply. This is one of the labelled LED indicators on the 6500 control panel's front fascia, confirmed directly from Protec's own product photography. The brochure documents that this indicator exists and its exact label, but — being a sales brochure, not an installation or commissioning manual — it does not describe the underlying cause, the specific conditions that trigger it, or the clearing procedure. Those details require the panel's installation/commissioning manual, which sits behind Protec's Client Support Portal login and was not accessed for this entry.
The "System Fault" LED on the 6500 panel's indicator strip. This is one of the labelled LED indicators on the 6500 control panel's front fascia, confirmed directly from Protec's own product photography. The brochure documents that this indicator exists and its exact label, but — being a sales brochure, not an installation or commissioning manual — it does not describe the underlying cause, the specific conditions that trigger it, or the clearing procedure.
