2.7.2 INPUT
TYPES
Each AZC can be programmed with one of ten different input types (refer Section 4.7).
These types are defined as follows and in Table 2.1.
Input Type 1 : Standard
Standard detector circuit without AVF. Both MCPs and detectors are allowed. Delay
into alarm is 2 seconds.
Input Type 2 : AVF/RAD
Standard detector circuit with AVF. MCPs are allowed and override AVF. AVF
sequence is: 2 seconds before first recognition, 5 second delay, 5 second reset, 2
second ignore, 2 second alarm recognition, 150 second acceptance period.
Input Type 3 : SAD
AS1668 SAD circuit (Supply Air Detector). 0-17V band is alarm with 2 seconds delay
into alarm and 60 seconds delay out of alarm. The detector must be non-latching and
the zone should be programmed as non-latching.
Input Type 4 : AVF/SAD
AS1668 AVF/SAD. 0-17V band is alarm with AVF (as for circuit type 2 AVF/RAD).
Delay out of alarm is 60 seconds. The detector must be non-latching and the zone
should be programmed as non-latching. 60 seconds of continuous non-alarm must be
present on the AZC input before the zone indicates non-alarm.
This input type can also be used with latching detectors that have a high alarm voltage
(up to 17V), when AVF is required (e.g. with IS isolating repeaters). Configure the
zone as latching. When the zone is reset the detector will be reset and the zone taken
out of alarm immediately, overriding the 60 second delay out of alarm.
Input Type 5 : Flowswitch
0-13V band is alarm with 20 second delay into alarm. 13-17V band is normal. The
detector is non-latching and the zone should be programmed as non-latching. 20
seconds of continuous alarm must be present on the AZC input before the zone
indicates alarm.
Input Type 6 : Standard/No MCP
Standard detector circuit without AVF. MCPs are not allowed and 13-17V band is
interpreted as fault to provide line leakage fault indication. The delay into alarm is 2
seconds. The delay into fault for 13-17V band is half a second.
Input Type 7 : AVF/RAD/No MCP
Standard detector circuit with AVF as for Type 2 AVF/RAD except that MCPs are not
allowed and 13-17V band is interpreted as fault to provide line leakage fault indication.
The delay into fault for 13-17V band is half a second.
Input Type 8 : Fast Supervision
13-17V band is alarm with half a second delay into alarm. 0-13V band is fault
providing both short circuit and open circuit fault detection. This is typically used for
sub-panel monitoring with sub-panel alarm relay in series with 15V zener diode. The
delay into fault for 0-13V band is half a second.
