Test Fires Activate fault relay.
This feature was provided so that when connected to a shopping mall the main operator needed to
know when a test was been carried out by individual shop units. During a weekly or walk test the fault
relay will change state to warn the centre that a test was in progress rather than a true fire.
Abnormal Comms Detection.
Abnormal comms has always been monitored within the loop code, however when any abnormal
comms is generated by raised background current this will generate a fault on the panel. This is a
requirement for EN54 part 13
Fast Automatics.
The introduction of a more robust response to electrical noise on the loop wiring has slightly slowed
the response of smoke detectors on larger loops. Whilst still within the requirement of EN54, fast
automatics have been introduced to provide an interrupt to speed up the response to an alarm
condition.
Opto Fire and Fault Threshold override.
The thresholds for fire and fault are defaulted to 60 and 10, these two buttons can be used to lower
these thresholds down to 53 and 3 respectively.
FIG 31
Global Weekly Walk tests
If the panel is part of a Network, the customer may require the weekly and walk tests to be transmitted
across the network
– this is defaulted to activate the local panel only.
This feature allows the customer to globally test the system.
