BEFORE INSTALLING
Read System Sensor’s
Applications Guide for System Smoke Detectors
(SPAG91), which provides detailed information on detector spacing, place-
ment, zoning, wiring, and special applications. This document is available
online from System Sensor. NFPA 72 guidelines should be observed.
NOTICE
: This manual should be left with the owner/user of this equipment.
IMPORTANT
: The detector used with this base must be tested and maintained
regularly following NFPA 72 requirements. The detector should be cleaned at
least once a year.
GENERAL DESCRIPTION
The sounder base was designed specifically to meet the needs of dwelling unit
applications. It offers maximum flexibility in configuration and operation to
meet or exceed the requirements of UL268 and UL464.
The sounder base is capable of producing either the distinctive three-pulse
temporal pattern (ANSI Temporal 3) fire alarm signal now required by NFPA
72 for commercial and residential applications or a continuous tone by simply
removing the included jumper from the device.
The sounder base is intended for use with intelligent systems. The sounder
base requires an external 24 VDC power supply. The connections for the
external power supply and the communication loop are isolated to prevent
electrical interaction between them. Refer to the panel manual for maximum
allowable number of units per loop.
NOTE
: For NFPA72 Installations, the Temporal 3 tone should be used for public
mode evacuation.
NOTE: When not used as a supplementary evacuation system, the external 24
VDC supply shall be treated as a component of the main power supply system
and shall fall under the requirements of the main power supply system per
NFPA 72.

-inch octagon, single gang and
double gang junction boxes.
1. Connect field wiring to terminals, as shown in Figure 1 and 3.
2. Attach the mounting plate to the junction box as shown in Figure 2.
3. To mount the sounder base, hook the tab on the sounder base to the groove
on the mounting plate.
4. Then, swing the sounder base into position to engage the pins on the
product with the terminals on the mounting plate.
5. Secure the sounder base by tightening the mounting screws.
6. Install a compatible smoke detector as described in the installation manual
for the detector.
INSTALLATION AND WIRING GUIDELINES
All wiring must be installed in compliance with all applicable local codes
and any special requirements of the authority having jurisdiction. Proper wire
gauges should be used. The conductors used to connect smoke detectors to
control panels and accessory devices should be color-coded to reduce the like-
lihood of wiring errors. Improper connections can prevent a system from re-
sponding properly in the event of a fire.
For signal wiring (the wiring between interconnected sensors or modules),
it is recommended that the wire be no smaller than 18 AWG (0.823 square
mm). Wire sizes up to 12 AWG (3.31 square mm) may be used with the base.
The base will be shipped with the screw terminals set for 14 AWG wiring. If
12 AWG wire is used, back out the screws to allow the wire to fit beneath the
clamping plates.
