Master Reset

A Master Reset is not accessed through the programming menus. It occurs automatically when the

Main Panel power is cycled (both primary and secondary supplies removed and reconnected). It also

occurs when the PCB mounted push button fitted on the rear of the Main Panel main PCB is pressed.

A Master Reset (re)sends all settings to all sub-panels. Settings are otherwise only sent to sub-panels

when they are changed using the programming functions.

When no detectors are isolated the Master Reset settings download will complete within 15 seconds

(even with 32 sub-panels connected). This therefore happens whilst the INITIALISING message is

being displayed. In the worst case (where 32 sub-panels are connected, all loops are fully populated

and all detectors are isolated) this download will take 240 seconds.

In parallel with the settings download the sub-panels will power off their an analogue loops for a

period of 8 seconds [reset] then allow an analogue loop charge up of 15 seconds before

commencement of loop polling.

In Active Mode when the settings download is complete, and polling has commenced, the

Discovery detectors are written to to set their LED ‘flash when polled’ status and their sensitivity

mode. This takes up to 30 seconds.

In Installation Mode the Discovery write does not start until at least 30 seconds of polling has

elapsed so that the presence of the Discovery devices can be first learned.
