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.
