Applications
NFPA 72 Proprietary Fire Alarm Systems
4.5 NFPA 72 Proprietary Fire Alarm Systems
When connected and configured as a protected premises unit with UDACT or UDACT-2, the NFS-
320/E will automatically transmit General Alarm, General Trouble, and General Supervisory
signals to a listed compatible Protected Premises Receiving Unit. See the
UDACT Manual
or
UDACT-2 Manual
for compatible receiving units. A simplified drawing of connections between the
receiving unit and the NFS-320/E protected premises unit is shown in Figure 4.4.
Connect the receiving unit to the protected premises unit as shown in Section 4.3 “NFPA 72 Central
or Remote Station Fire Alarm System (Protected Premises Unit)”.
For information on installing and programming the Receiving unit, refer to the documentation for
that control panel.
4.6 Fire/Security Applications
4.6.1 General Operation
The control panel can be used as a combination Fire/Security system when installed and operated
according to the instructions in this section.
For security applications, program one or more monitor modules (listed for security applications)
with the
SECURITY
Type Code, and wire as shown in Figure 4.6. Activating this type of module
lights the
SECURITY
LED, and displays a security alarm condition on the control panel LCD display.
The panel sounder will sound until the Security alarm is acknowledged. You can also program
additional sounders or output devices to activate with the security alarm initiating device. The
SECURITY
Type Code is designed to indicate an alarm as follows: (a) on an open or short circuit; or
(b) on a ±50% change in resistance value from the End-of-Line resistor value.
A tamper switch installed in the cabinet door will indicate a door tamper condition whenever the
door is open. If the control panel indicates a Security alarm, you can acknowledge, silence, and
reset the condition from the control panel.
When the system resets, a 30-second exit timer starts. During this time the tamper switch and all
Security alarms are ignored. There is no entrance delay timer.
NOTE:
NFS-320/E/C is not approved for use in security applications in Canada.
