4.5 Fire/Security Applications
4.5.1 General Operation
The NFS2-3030 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 module (listed for security applications)
with the
SECURITY
-L,
SYSTEM
MONITOR
, or
AREA
MONITOR
Type Codes, and wire as shown in
Figure 4.6. Activating these types of modules lights the
SECURITY
LED, and displays a security
alarm condition on the primary display. The panel sounder will sound until you acknowledge the
Security alarm. You can also program additional sounders or output devices to activate with the
security alarm initiating device. These type codes are designed to indicate an alarm in one or more
of the following situations:
(a) on an open or short circuit
(b) on a ±50% change in resistance value from the End-of-Line resistor value
(c) on loss of communication with the device.
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 perform acknowledge, signal
silence, and system reset from the control panel.
Damage can result from incorrect wiring connections.
4.5.2 General Security Requirements
The following security requirements must be met:
•
Use AMPS-24/E power supply.
•
Shielded cable must be used on all input/output wiring associated with security functions.
•
SLC Loop Shielding (refer to the SLC Wiring Manual).
•
Security Module I/O Circuit Shielding - terminate the shield at earth ground at the junction box
containing the module.
•
When employed as a Protected Premises Unit, the NFS2-3030 cabinet door must be wired with
an STS-1 Tamper Switch that is monitored by the control panel.
