SA-DACT FCC information
Cautions
• To ensure proper operation, this dialer must be installed according to the enclosed
installation instructions. To verify that the dialer is operating properly and can successfully
report an alarm, it must be tested immediately after installation, and periodically thereafter,
according to the enclosed test instructions.
• In order for the dialer to be able to seize the phone line to report an alarm or other event
when other customer equipment (telephone, answering system, computer modem, etc.)
connected to the same line is in use, the dialer must be connected to a properly installed
RJ-31X jack. The RJ-31X jack must be connected in series with, and ahead of, all other
iv P/N 3102351-EN • REV 005 • ISS 28DEC18
equipment attached to the same phone line. Series installation of an RJ-31X jack is
depicted in the wiring diagram. If you have any questions concerning these instructions,
you should consult your telephone company or a qualified installer.
Testing
When programming emergency numbers or making test calls to emergency numbers, remain
on the line and briefly explain to the dispatcher the reason for the call. When system
maintenance, testing or modifications could result in the transmission of signals from the fire
alarm system to a supervising station, consult the supervising station to determine the best
time to send these signals (i.e., “off-peak” hours).
Compliance
• This dialer complies with Part 68 of the FCC rules and the requirements adopted by the
Administrative Council for Terminal Attachments (ACTA). A label attached to the dialer
contains, among other information, a product identifier in the format US:AAAEQ##TXXXX.
If requested, this information must be provided to the telephone company.
• The plug and jack used to connect the dialer to the premises wiring and telephone network
must comply with the applicable FCC Part 68 rules and requirements adopted by ACTA.
The dialer must be connected to a compliant RJ-31X or RJ-38X jack using a compliant
cord. If a modular telephone cord is supplied with the dialer, it is designed to meet these
requirements. See installation instructions for details.
• A ringer equivalence number (REN) is used to determine how many devices you can
connect to a telephone line. If the total REN value for all devices connected on a telephone
line exceeds that allowed by the telephone company, the devices may not ring on an
incoming call. In most (but not all) areas the total REN value should not exceed 5.0. To be
certain of the total REN value allowed on a telephone line, contact the local telephone
company.
• For products approved after July 23, 2001, the REN is part of the product identifier in the
format US:AAAEQ##TXXXX. The digits ## represent the REN without a decimal point.
Example: 03 is a REN of 0.3. For earlier products the REN is listed separately.
• If the dialer is harming the telephone network, the telephone company will notify you in
advance that temporary discontinuance of service may be required. If advance notice isn’t
practical, the telephone company will notify you as soon as possible. You will also be
advised of your right to file a complaint with the FCC, if you believe it is necessary.
• The telephone company may make changes to its facilities, equipment, operations, or
procedures that could affect the operation of the dialer. If this happens, the telephone
company will provide advance notice in order for you to make necessary modifications to
maintain uninterrupted service.
• If you are experiencing problems with the dialer, contact the manufacturer for repair or
warranty information. If the dialer is harming the telephone network, the telephone
company may request that you disconnect the dialer until the problem is resolved.
P/N 3102351-EN • REV 005 • ISS 28DEC18 v
• The dialer contains no user serviceable parts. In case of defects, return the dialer for repair.
• You may not connect the dialer to a public coin phone or a party line service provided by
the telephone company.

Notes for Figure 16 and Figure 17.
[1] For Class A wiring, isolator modules and isolator detector bases are required to prevent wire-to-wire shorts on
the signaling line circuit wiring from adversely affecting other segments of the loop. Do not install more than 50
addressable devices between isolators, per NFPA 72.
[2] For Class X wiring, isolator modules and isolator detector bases are required to prevent wire-to-wire shorts on
the signaling line circuit wiring from adversely affecting any devices of the loop.
Loop card LEDs
There are two LEDs on the card for each SLC that indicate SLC communication status. See
Figure 18 and Figure 19 for LED functions and location.
The installation location of the card on the panel determines what panel SLC the LEDs are
associated with for VS4 that support dual SLC cards and provide two installation locations.
See Figure 20.

Alarm, trouble, and supervisory relay wiring (TB3)
The control unit provides three pre-programmed common event relays for alarm, supervisory,
and trouble events. These relays are not field configurable.
• The trouble relay changes over on any trouble event (common trouble)
• The supervisory relay changes over on any supervisory event (common supervisory)
• The alarm relay changes over on any alarm event (common alarm)
Note: Relay circuits can only be connected to power-limited sources. Relays are not
supervised.
Relay specifications
• Alarm and trouble: Form C, 24 VDC at 1 A resistive, Class E
• Supervisory: Form A, 24 VDC at 1 A resistive, Class E

Auxiliary/smoke power output wiring
The control panel provides resettable and continuous AUX power output circuits. Use the
resettable AUX power output for devices such as four-wire detectors or beam detectors. Use
the continuous AUX power output for devices such as remote annunciators or door holders.
Notes
• If you do not need resettable AUX power, you can configure the resettable AUX power
output to supply continuous power.
• For a complete list of devices that can be connected to this circuit, refer to the VS1 and
VS4 Series Compatibility List (P/N 3102354-EN).
Circuit specifications
• Circuit voltage range: 21.9 to 28.3 V
• AUX 1 + AUX 2 can supply 0.5 A of standby current. If more than 0.5 A of standby current
is required, you must use a power-limited and regulated 24 VDC auxiliary/booster power
supply that is UL/ULC and FM Listed (if the installation requires FM regulation) for fire
protective signaling systems.
• For a complete list of auxiliary/booster power supplies, refer to the VS1 and VS4 Series
Compatibility List (P/N 3102354-EN). Also refer to the REL Technical Reference Manual
(P/N 387515-EN) for a list of REL compatible power supplies, if you need to power REL
module.

Chapter 1: Installation and wiring
(1) Auxiliary/Smoke power output
(2) Resettable (AUX 2)
(3) Continuous (AUX 1)
• Continuous circuit (AUX power 1): 24 VDC nominal at 500 mA (up to 1 Amp of alarm
current is available on AUX 1 if you reduce the total available control panel NACs alarm
current by the total amount of AUX 1 + AUX 2 alarm current over 500 mA). Use this circuit
to supply 24 VDC continuous power. A SMK module is required when using the UM or
MAB module to support two-wire smoke detectors.
• Resettable circuit (AUX power 2): 24 VDC nominal at 500 mA (standby and alarm). Use
this circuit to provide 24 VDC resettable power. You can configure AUX power 2 as a
continuous circuit if you do not need a resettable circuit.
• Special application circuits
• Ground fault impedance: 0 to 5 kΩ
• Supervised and power-limited
