Supervisory Configuration
If DIP switch #3 - “Supervisory on Zone 4” is selected (see "Setting Mode of Operation" on page 27) IDC
#4 will act as a supervisory circuit. Jumpers SUPV1 and SUPV2 control how the NACs respond.
1.
No jumper is cut -
Both NACs activate for supervisory conditions on IDC #4.
2.
SUPV1 jumper is cut -
NAC #1 activates with an alarm on IDC #1, IDC #2, or IDC #3.
NAC #2 activates with a supervisory condition on IDC #4 only.
3.
SUPV2 jumper is cut -
NAC #1 and NAC #2 will not activate for supervisory conditions; panel piezo will sound.
Note:
Do NOT cut both SUPV1 and SUPV2 jumpers.
Optional modules react to supervisory conditions as follows:
If a 4XZMF (4412ZM) Zone Relay Module is used, Relay 4 will activate for supervisory conditions.
If an RZA-4XF Remote Annunciator is used, the fourth LED (red) will annunciate supervisory
conditions.
To locate jumpers on the board, see Figure 1 on page 9.

Alarm Relay
One Form-C dry contact alarm relay is provided in the basic panel for controlling supplementary devices.
Contacts are rated 2 amps at 30 VDC and 0.5 amps at 30 VAC (resistive) and are non-silenceable when
an alarm occurs.
Trouble Relay
One Form-C dry contact trouble relay is provided in the basic panel for controlling supplementary devices.
It is rated 2 amps at 30 VDC and 0.5 amps at 30 VAC (resistive) and will restore to normal when the trouble
condition is cleared.
Note:
Power connected to these relay contacts must come from a power-limited supply. Power may be obtained from
TB2 Terminals VU, VR or VNR, or a UL-listed power-limited power supply.
