Installation
Secondary Power Source (Batteries)
Observe polarity when connecting the battery. Connect the battery cable to J12 on the main circuit board using the plug-in connector and
cable provided. The battery charger is current-limited and capable of charging sealed lead acid batteries. The charger shuts off when the
system is in alarm.
WARNING: SULFURIC ACID
!
BATTERIES CONTAINS SULFURIC ACID WHICH CAN CAUSE SEVERE BURNS TO THE SKIN AND EYES AND CAN
DESTROY FABRICS. IF CONTACT IS MADE WITH SULFURIC ACID, IMMEDIATELY FLUSH THE SKIN OR EYES WITH
WATER FOR 15 MINUTES AND SEEK IMMEDIATE MEDICAL ATTENTION.

2.3 Input Circuits

The SFP-5UD has five IDCs (Initiating Device Circuits) and the SFP-10UD has ten IDCs. Each circuit is compatible with System Sen-
sor's i smoke detectors which generate a maintenance signal when the detector becomes dirty and a separate supervisory 'freeze' signal
3
when ambient temperature falls below the detector rating of approximately 45
ohms (700 ohms per zone for linear heat detection). Do not use 2-wire smoke detectors on input zones used for linear heat detection. The
field wiring for each zone is supervised for opens, shorts and ground faults. All conditions are visually and audibly annunciated.
Each circuit is configured for Style B (Class B) operation and will accept i
as conventional 2-wire or 4-wire, 24 VDC smoke detectors. Refer to the Notifier Device Compatibility Document for a list of compatible
devices.
