7.2 CONFIGURING CIRCUITS (AZCS)
7.2.1 GENERAL
When the configure circuits option is selected, the LCD displays a message, and then
automatically selects AZC 01, or the last AZC programmed. For the selected AZC it displays
a list of attributes which can be programmed, and the option that is currently selected for that
attribute. The list may be stepped through by use of ! " keys. As each attribute is
selected, the options for it are displayed on the bottom line.
Attributes include:
Alarm Text; Mode; Delay; Voltage Band B1; Voltage Band B3; Delay 1; Delay 2; Instant
Alarm Text.
When all the desired attribute options have been selected, press "ACK" to save the data,
and then use "NEXT" or "PREV".
7.2.2 ALARM TEXT
The Alarm text (detector type) selected is displayed as part of the Alarm message on the
LCD and printer. The software makes allowance for the fact that MCPs may be connected
to a circuit with detectors. For example, if an AZC has both smoke detectors and MCPs on
it, then the alarm text should be Smoke.
An AZC Alarm (see Section 7.2.5) will be displayed as a "SMOKE" Alarm, but an AZC
Instant Alarm (MCP) will be displayed as a "MANUAL" Alarm (see below).
Of the 9 options of alarm text, 1-7 have default text as shown on Fig 7.1.1 (i.e. 1 smoke, 2
heat, etc) but 8 and 9 are blank. All are programmable as described in Section 6.4.3.
The default alarm text is "SMOKE".
Instant Alarm Text
The Instant Alarm text is also programmable with the same options. The default is
"MANUAL".
7.2.3 MODE
The electronics on the 8 Zone Module which interfaces to an AZC (i.e. detector circuit) has a
15mA current limited supply from +22V, and a pull up resistor to +22V. These are software
controlled (i.e. turned on or off) and different combinations are used for different applications,
giving five modes of operation as follows.
Select the correct mode for the particular type of detectors being used on the AZC (refer to
Appendix A2).
Mode 1 Standard
15mA current limit from +22V supply.
2k7 EOL.
Suits most detectors.
Mode 2 High Current
15mA current limit from +22V supply.
2k7 EOL.
