restore will immediately remove the AL 13 from the display, but 7 minutes of constant restore
condition needs to elapse before transmission of the pin 13 restore.
The 7 minute time delay can be configured through the web console by typing a new value 0-7
in the “Mains Fail delay” field. If the “Mains Fail delay” is set to 0, then pin 13 can be used as a
general purpose alarm input. (Subject to ARC acceptance).
Output 1
Output 1 acts as the communications fail output. The mode of operation can be selected
through the F8 button menu. (see config section)
By default output 1 acts as a BSIA form 175 output. (F8=1). This allows the alarm panel to
interrogate path faults as single path or dual path. That is, the output is normally low when
both paths are OK.
By default the output will switch high, following either path fail, once the relevant ‘debounce’
time has expired. (Defaults 2 minutes for IP, 15 minutes for GPRS and 15 minutes for PSTN)
If ATS input (pin 11) is toggled during the fail period, i.e. (panel interrogation) then output 1 will
either pulse low to indicate a single path failure, or remain high to indicate a dual path failure.
The unit also supports inverted mode BSIA175 operation by learning pin 11 to be positive
removed.
