NFS-640 Installation Manual P/N 51332:B2 07/27/2004 81
Appendix D Canadian Applications
D.1 Standalone Application
D.1.1 NFS-640 with KDM-2
If using KDM-2 as the primary display for NFS-640, an ACS series annunciator must be mounted
adjacent to the panel or within NFS-640 enclosure.
D.1.2 NFS-640 with NCA
Network Control Annunciator (NCA) with 640-character, multi-line display complies with ULC
requirements when used as the primary display for NFS-640.
D.2 Local Network Application
To meet ULC requirements, the network’s Manual Controls may only be operated from one location at
any given time.
When panels networked (using NCM Network Control Modules), employ AKS-1 Key Switch on each
panel’s Primary Annunciator to enable its functions. NCA may be a Primary Annunciator when AKS-
1B is installed. Refer to the NCA Manual for more information.
An NCA or Network Control Station (NCS) may be employed as a Display and Control Center. In the
event that communication fails between the panels and the Control Center, the panels will continue to
function in local/standalone mode.
D.3 Automatic Alarm Signal Silence
If selecting this feature for a system requiring annunciators, consult the Authority Having Jurisdiction.
D.4 Annunciator Applications
1. In Canada, the ACM series annunciator modules must be used to annunciate the fire alarm input
points/zones only, if no multi-line sequential display is installed.
2. For Canadian applications, the following LED colors must be employed:
• Red must be used to indicate active alarm inputs.
• Yellow must be used to indicate supervisory, burglary or trouble signals.
• Green must be used to indicate the presence of power or an activated output.
D.5 Releasing Devices
Supervision for shorts is required; use REL devices and type code REL CKT ULC.
(With on-board NACs, use REL-2.2K; with FCM-1 modules use REL-47K. Refer to Section 4.5
“Releasing Applications” for details.
