Pin inputs
Of the 16 alarm pin inputs, all behave as general purposes inputs with the following exceptions:
• Pin 1 must be used for Fire alarm when ACK NAK
outputs are used for Fire panels. The signalling
unit, when configured, provides an acknowledge
and not acknowledged indication via use of
outputs 2 (FUNC) and 3 (FIRE).
• Pin 4 can have an RPS output or a Keyswitch
associated with it. (See output 2 RPS or a
Keyswitch (N/A for FIRE config)).
• Pin 11 acts as an ATS input as per the
requirements of the BSIA form 175 document.
This applies only when output 1 is set to BSIA
mode. N/A when configured for Fire.
• Pin 13 acts as an AC fail input and therefore has
a default 7 minute delay before a Pin 13 alarm is
transmitted. It also has a 7 minute delay before
a reset is sent. On presenting an alarm condition
to Pin 13, the unit’s display will show the alarm
immediately but 7 minutes of constant alarm
condition needs to elapse before transmission.
Similarly, restoring Pin 13 will immediately
remove Pin 13 from the display, but 7 minutes
of constant restore condition needs to elapse
before transmission of Pin 13 restore.
• The 7 minute time delay can be configured
through the web portal or app by typing a new
value up to 99 (mins) 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).
• Pins 1 – 16 can be set up for End of Line and Dual
End of Line interconnection monitoring see
descriptions on end of line monitoring.
Default outputs
Output 1 (COMMS)
Output 1 acts as the Communications fail output.
The mode of operation can be selected through the
configuration menu (see Configuration section).
1. BSIA form 175 output
This allows the alarm panel to interrogate path
faults as single path or dual path. By default the
relay output will switch, following either path
fail, once the relevant timer has expired.
If ATS input (Pin 11) is toggled during the fail
period, e.g. (panel interrogation) then Output 1
will either switch back to indicate a single path
failure, or remain operated to indicate a dual
path failure.
The unit also supports inverted mode BSIA175
operation by learning Pin 11 to be positive
removed.
2. Single path fault
Will operate when either path is in fault.
3. Dual path fault
The relay will operate when both the IP
and Mobile path are in fault.
4. IP Path fault
To be used in conjunction with Output 2
for the Mobile path.
