Configuration; Alarm Dependency (Zone Coincidence Detection); Non-Latching Detection Zones - Numens 4001 Series Installation And Service Manual

8. CONFIGURATION

Various functions can be configured. For configurable functions, follow the sections below.
8.1.

Alarm Dependency (Zone Coincidence Detection)

Alarm Dependency requires two detection zones to report a fire before the Fire Alarm relay operates.

Alarm Dependency has not been assessed for compliance with EN 54-2.

Alarm Dependency only operates the Fire Relay.

If one of the paired detection zones is disabled, the Fire Relay will not operate.

Non-latching detection zones should not be configured for Alarm Dependency.
8.1.1. Configuration
To configure Alarm Dependency, complete the following steps:
1) Enter Access Level 3.
2) Press the FAULT RELAY button. Check that the FAULT RELAY LED is on and the ACK LED flashes.
3) Press the ACK button to confirm. Check that the ACK LED is off.
4) Use the NEXT button to step through the Zone pairs for Alarm Dependency (Zones 1 & 2, Zones 3 & 4,
Zones 5 & 6, etc). Check that the associated LEDs (B 1 & B 2, B 3 & B 4, B 5 & B 6, etc) are on.
5) When the Zone pair is selected, confirm the selection by pressing the ACK button. Check that the
associated "A" LEDs are on.
6) If required, repeat steps 2 ~ 4 for additional Zone pairs.
7) Press the FAULT RELAY button to exit Alarm Dependency configuration. Check that the FAULT RELAY
LED is off, the ACK LED is off, and the A and B CONFIGURE LEDs are off.
8.1.2. Cancel Configuration
To remove Alarm Dependency, complete the following steps:
1) Enter Access Level 3.
2) Press the FAULT RELAY button. Check that the FAULT RELAY LED is on and the ACK LED flashes.
3) Press the ACK button to confirm. Check that the ACK LED is off.
4) Use the NEXT button to step through the Zone pairs for Alarm Dependency (Zones 1 & 2, Zones 3 & 4,
Zones 5 & 6, etc). Check that the associated LEDs (B 1 & B 2, B 3 & B 4, B 5 & B 6, etc) are on.
5) When the Zone pair is selected, confirm the selection by pressing the ACK button. Check that the
associated CONFIGURE "A" LEDs are off.
6) If required, repeat steps 2 ~ 4 to cancel the configuration of other Zone pairs.
7) Press the FAULT RELAY button to exit Alarm Dependency configuration. Check that the FAULT RELAY
LED is off, the ACK LED is off, and the CONFIGURE "A" and "B" LEDs are off.
8.2.

Non-Latching Detection Zones

Detection zones can be configured not to latch incoming fire signals.

Non-latching Detection Zones do not comply with EN 54-2.

Incoming fire signals for non-latching detection zones will activate Alarm Zones, but
will not activate the Alarm Relay(s).

Faults are non-latching. The Fault Relay will not activate.
8.2.1. Configuration
To configure Non-latching Detection Zones, complete the following steps:
1) Enter Access Level 3.
2) Press the ALARM RELAY button. Check that the ALARM ZONES LED and the ACK LED flashes.
3) Press the ACK LED to confirm. Check that the ACK LED flashes and the ALARM RELAY LED is on. The
CONFIGURE "A" LEDs will display any detection zones that are currently configured for non-latching
operation.
4) Use the NEXT button to step through the Zones. The CONFIGURE "B" LED will show the Detection Zone
