Replacement keys 
The reset/test key is an industry-standard ‘Burgess TOK 1’ type. Replacement keys are widely available from 3rd-

party suppliers, or as a complete replacement switch and two keys from Scope (part code K23FBA-123).

Troubleshooting  

Symptom 

Possible Cause(s) 

Remedial Action 

Display shows 

 

Interference caused by other 

equipment using the same 

frequency. 

Conduct a radio survey to establish the source of 

the interference, then either remove/modify the 

interfering equipment or change the F-Link system 

to use a clear frequency channel (see 2.1 on page 

5). 

 fault and/or 

alarms not getting 

through. 

External interference. 

As above. 

Inadequate current available 

from power supply. 

Ensure the power supply can provide at least 

500mA (½ Amp) at 10v-30v DC, and/or fit a 

separate PSU.  
(If the F-Link cannot draw enough current quickly 

enough when it needs to transmit then this can 

stop signals getting through). 

Site attenuation (signal being 

blocked by walls etc.) 

Conduct a radio survey to establish achievable 

coverage and the optimum aerial type and location.  

Depending on the survey results, relocate/upgrade 

aerials as required (see 3.1.1 on page 9). 

Zone “stuck” on / not 

resetting. 

Zone input still active. 

Restore the zone input (short for normally-closed 

zones and open for normally-open zones). 

Zone is designed to latch (output 

mode set to Latched). 

Reset the F-Link using the keyswitch. 

Intermittent transmission 

problem. 

See under “LINK FAIL” above. 

 fault. 

There is a fault on the 

interconnect wiring or the 

equipment being monitored by 

the FP-Link input (e.g. a local 

PSU). 

Rectify the fault on the other equipment/wiring.  If 

nothing is connected to the FP-Link input, check the 

680  end-of-line resistor is securely fitted to the 

FP-Link terminals in the relevant F-Link unit.
