2. Fire Supervisory Response On Short Circuit Or Open Circuit Selection

(new program field 3*13)

Field 3*13 allows the installer to select whether a short circuit or open circuit fault will initiate a

supervisory response on zones programmed for fire supervisory response (response type 18).

3*13 0 = trouble on open / supervisory on short;

1 = supervisory on open / supervisory on short

When field 3*13 is set to "0" (default), zones programmed for fire supervisory response provide

trouble on open / supervisory on short. When field 3*13 is set to "1", zones programmed for fire

supervisory response provide supervisory on open / supervisory on short response.

3. Extended waterflow and fire supervisory delay (new program field 3*18)

Field 3*18 allows the fire waterflow (response type 17) and fire supervisory (response type 18) zone

delay programmed in field 3*16 to be extended.

3*18 0 = no extended delay; 1 = delay in 3*16 times 4

When field 3*18 is set to "0" (default), the delay programmed in field 3*16 applies. When field 3*18 is

set to "1" the delay programmed in field 3*16 is multiplied by 4 (allowing delays up to 120 seconds).

4. Manual/Automatic fire Waterflow alarm silencing (new program field 3*14)

Field 3*14 allows the installer to select whether zones programmed for fire waterflow response

(response type 17) can be silenced manually (security code + OFF) or can be silenced automatically

when waterflow ceases.

3*14 0 = manual silencing only; 1 = automatic silence when waterflow ceases

When field 3*14 is set to "0" (default), waterflow zones can be silenced manually only, by entering the

security code + OFF. When field 3*14 is set to "1", waterflow zones will silence automatically when

waterflow ceases (provided that no other fire alarms are present).

Note that if field 3*14 is set for "1", entering security + OFF will not silence waterflow alarms while

water continues to flow.

5. Clarification of Duress Trigger Operation

The Installation Instructions currently state that the silent panic/duress trigger goes HIGH when a

silent panic or duress alarm occurs, and remains high until the security code + OFF is entered. This is

true when a silent panic alarm is initiated via a hardwired or polling loop zone. However, if the duress

alarm is initiated via console key depression, the silent panic/duress trigger remains high for about 2

seconds only, then returns to the low state.
