The GS690 addressable control and indicating panel forms the central part of a fire detection and alarm system. The
panel is available with 1 or 2 addressable loops and is easy to install and operate. A central microprocessor delivers
reliable operation and requires minimum maintenance.
The GS690 control and indicating panel is compatible with SITERWELL addressable detectors and other devices, such
as manual pull stations and audio/visual alarm devices. They are suitable for small and medium-sized buildings.
This Manual provides installers with instructions to install, use and service the GS690 control and indicating panel using
revision 1.0 operating firmware.
1. PRECAUTIONS FOR USE
1.1 Alarm System Limitations
An automatic fire alarm system–typically made up of smoke detectors, heat detectors, manual pull stations, audible and
visual warning devices, and a fire alarm control with remote notification capability–can provide early warning of a
developing fire. Such a system, however, does not assure protection against property damage or loss of life resulting
from afire. The Manufacturer recommends that smoke and/or heat detectors be located throughout a protected premise
following the recommendations of the current edition of the National Fire Protection Association Standard 72 (NFPA 72),
manufacturer's recommendations, State and local codes, and the recommendations contained in the Guide for Proper
Use of System Smoke Detectors, available for free download from the National Electrical Manufacturers Association,
NEMA web site at https://www.nema.org/Standards/Pages/Guide-for-Proper-Use-of-System-Smoke-Detectors.aspx A
study by the Federal Emergency Management Agency (an agency of the United States government) indicated that
smoke detectors may not go off in as many as 35% of all fires. While fire alarm systems are designed to provide early
warning against fire, they do not guarantee warning or protection against fire. A fire alarm system may not provide timely
or adequate warning, or simply may not function, for a variety of reasons:
Smoke detectors may not sense fire where smoke cannot reach the detectors such as in chimneys, in or behind walls,
on roofs, or on the other side of closed doors. Smoke detectors also may not sense a fire on another level or floor of a
building. Asecond-floor detector, for example, may not sense a first-floor or basement fire.
Heat detectors do not sense particles of combustion and alarm only when heat on their sensors increases at a
predetermined rate or reaches a predetermined level. Rate-of-rise heat detectors may be subject to reduced sensitivity
over time. For this reason, the rate-of-rise feature of each detector should be tested at least once per year by a qualified
fire protection specialist. Heat detectors are designed to protect property, not life.
Smoke detectors must be installed in the same room as the control panel and in rooms used by the system for the
connection of alarm transmission wiring, communications, signaling, and/or power. If detectors are not so located, a
developing fire may damage the alarm system, crippling its ability to report a fire.
Audible warning devices such as bells may not alert people if these devices are located on the other side of closed or
partly open doors or are located on another floor of a building. Any warning device may fail to alert people with a
disability or those who have recently consumed drugs, alcohol or medication.
Please note that:
 Strobes can, under certain circumstances, cause seizures in people with conditions such as epilepsy.
 Studies have shown that certain people, even when they hear a fire alarm signal, do not respond or comprehend the
meaning of the signal. It is the property owner's responsibility to conduct fire drills and other training exercise to make
people aware of fire alarm signals and instruct them on the proper reaction to alarm signals.
 In rare instances, the sounding of a warning device can cause temporary or permanent hearing loss.

The most common cause of fire alarm malfunction is inadequate maintenance. To keep the entire fire alarm system in
excellent working order, ongoing maintenance is required per the manufacturer's recommendations, and UL and NFPA
standards. At a minimum, the requirements of NFPA 72 shall be followed. Environments with large amounts of dust, dirt
or high air velocity require more frequent maintenance. A maintenance agreement should be arranged through the local
manufacturer's RE / DD / UM 3 / AVANI V 1.0- 01 representative. Maintenance should be scheduled monthly or as
required by National and/or local fire codes and should be performed by authorized professional fire alarm installers
only. Adequate written records of all inspections should be kept.
This system meets NFPA requirements for indoor dry operation at 0-49°C/32-120°F and at a relative humidity of 93 ±2%
RH (non-condensing) at 32 ±2°C/90 ±3°F. However, the useful life of the system's standby batteries and the electronic
components may be adversely affected by extreme temperature ranges and humidity. Therefore, it is recommended that
this system and all peripherals be installed in an environment with a nominal room temperature of 15-27°C/60-80°F.
Verify that wire sizes are adequate for all initiating and indicating device loops. Refer to manual Specifications section
for maximum allowable I.R. drop from the specified device voltage. Like all solid state electronic devices, this system
may operate erratically or can be damaged when subjected to lightning-induced transients. Although no system is
completely immune from lightning transients and interferences, proper grounding will reduce susceptibility. Overhead or
outside aerial wiring is not recommended, due to an increased susceptibility to nearby lightning strikes. Consult with the
Technical Services Department if any problems are anticipated or encountered.
Do not tighten screw terminals more than 9 in-lbs. Over-tightening may damage threads, resulting in reduced terminal
contact pressure and difficulty with screw terminal removal.
This system contains static-sensitive components.
Always ground yourself with a proper wrist strap before handling any circuits so that static charges are removed from the
body. Use static-suppressive packaging to protect electronic assemblies removed from the unit.
Follow the instructions in the installation, operating, and programming manuals. These instructions must be followed to
avoid damage to the control panel and associated equipment. FACP operation and reliability depend upon proper
installation by authorized personnel.

3. INSTALLATION
3.1 Installation Precaution
Electrical hazard: disconnect power from equipment prior to making any internal adjustments. This
equipment must have an Earth connection. Prior to installation, keep components wrapped in anti-static
material at all times.
FRAGILE: Inspect the equipment prior to installation. Do not install the equipment if damage is
apparent. If damaged, return to the supplier.
ELECTROSTATIC HAZARD: This is sensitive electronic equipment. Apply safe ant-static practices
when handling this equipment.
Disconnect AC power and batteries prior to removing or inserting circuit boards. Failure to do so
can damage circuits.
Remove all electronic assemblies prior to any drilling, filing, reaming, or punching of the
enclosure. When possible, make all cable entries from the sides or rear. Before making modifications,
verify that they will not interfere with battery, transformer, and printed circuit board location.
Follow the instructions in the installation, operating, and programming manuals. These instructions
must be followed to avoid damage to the control panel and associated equipment. FACP operation and
reliability depend upon proper installation by authorized personnel.
Like all solid-state electronic devices, this system may operate erratically or can be damaged when
subjected to lightning-induced transients. Although no system is completely immune from lightning
transients and interferences, proper grounding will reduce susceptibility. Overhead or outside aerial wiring
is not recommended, due to an increased susceptibility to nearby lightning strikes. Consult with the
Technical Services Department if any problems are anticipated or encountered.
Remove all electronic assemblies prior to any drilling, filing, reaming, or punching of the enclosure. When possible,
make all cable entries from the sides or rear. Before making modifications, verify that they will not interfere with battery,
transformer, and printed circuit board location.
Do not tighten screw terminals more than 1.0168 N-m. Over-tightening may damage threads, resulting in reduced
terminal contact pressure and difficulty with screw terminal removal.
All connection lines installations must meet local, national laws, regulations and requirements of electrical and
construction regulations.
3.2 Tools and Equipment
Before commencing installation, ensure all equipment and tools to mount and connect the equipment are available, such
as drills, mounting screws, cables and ladders.
3.3 Panel Mounting
When installation of all the cables has been completed, clean the interior of the enclosure ensuring all masonry debris and
drilling swords are removed.
