Fire Alarm System Limitations
An automatic fire alarm system—typically
made up of smoke detectors, heat detectors,
manual pull stations, audible warning
devices, and a fire alarm control panel 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 a fire.
The Manufacturer recommends that smoke
and/or heat detectors be located throughout
a protected premise following the
recommendations of the National Fire
Protection Association Standard 72 (NFPA
72), EN54 Standards, and manufacturer’s
recommendations.
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. A
second-floor detector, for example, may not
sense a first-floor or basement fire.
Particles of combustion or “smoke” from a
developing fire may not reach the sensing
chambers of smoke detectors because:
• Barriers such as closed or partially closed
doors, walls, or chimneys may inhibit particle
or smoke flow.
• Smoke particles may become “cold,”
stratify, and not reach the ceiling or upper
walls where detectors are located.
• Smoke particles may be blown away from
detectors by air outlets.
• Smoke particles may be drawn into air
returns before reaching the detector. The
amount of “smoke” present may be
insufficient to alarm smoke detectors.
Smoke detectors are designed to alarm at
various levels of smoke density. If such
density levels are not created by developing
fire at the location of detectors, the detectors
will not go into alarm.
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.
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:
• 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.
A fire alarm system will not operate without
any Electrical power. If AC power fails, the
system will operate from standby batteries
only for a specified time and only if the
batteries have been properly maintained and
replaced regularly.
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 as per the manufacturer's
recommendations, and UL and NFPA
standards and EN54 standards. At a

TSGR-21 GAS Release Panel User Manual
Vighnaharta Technologies Pvt. Ltd. Page 3of 43
minimum, the requirements of NFPA 72 or
EN54 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
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.
Installation Precautions
WARNING - Several different sources of
power can be connected to the fire alarm
control panel. Disconnect all sources of
power before servicing. Control unit and
associated equipment may be damaged by
removing and/or inserting cards, modules, or
interconnecting cables while the unit is
energized. Do not attempt to install, service,
or operate this unit until manuals are read
and understood.
CAUTION - System Re-acceptance Test after
Software Changes: To ensure proper system
operation, this product must be tested in
accordance with NFPA 72 after any
programming operation or change in site-
specific software. Reacceptance testing is
required after any change, addition or
deletion of system components, or after any
modification, repair or adjustment to system
hardware or wiring. All components, circuits,
system operations, or software functions
known to be affected by a change must be
100% tested.
This System meets NFPA & EN54
requirements for operation 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 its
peripherals be installed in an environment
conditions specified.
Verify that wire sizes are adequate for all
initiating and indicating device loops.
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, or
printed circuit board location.
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.
Like all solid state electronic devices, this
system may operate erratically or can be
damaged when subjected to lightning
induced transients. Due to such activity there
may be temporary degradation or damage
occurred. Although no system is completely
immune from lightning transients and
interference, proper grounding will reduce
susceptibility.
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. Fire Panel operation and
reliability is depend upon proper installation.

1. Product Description
1.1 Overview:
TSGR-21 is basically used for fire detection as well as suppression panel to suppress fire using gas
release system. Main purpose of the system is to monitor fire and pressure switch of TSGR-21 gas
release system and if fire is detected, panel will activate the solenoid valve to release the gas
cylinder and display shows the fire zone. This system also has main and stand by gas cylinder
pressure monitoring. In case, the main gas cylinder consumed and gone for refilling then in that
case the stand by gas cylinder will be ready for use by selecting it from menu.
The panel includes local buzzer, LEDs for indications and with LCD display, keypad for manual
operation and configuration. The TSGR-21 allows the flexibility in most fire suppression
application. This TSGR-21 is compatible with smoke detectors and heat detectors that can
continuously monitor for trouble and fire condition.

The following diagram shows basic components of TSGR-21 system. It consists of various smoke and heat
detectors, AC power source, Notification devices like NAC or sounder, Fire Suppression and Releasing agent Gas
based extinguishers, SCADA communication cables, all connected to control panel.
NOTE: Connect all EOL of 4.7K ohms
WARNING:
Several different sources of power can be connected to this panel. Disconnect all sources of power before
servicing. The panel and associated equipment may be damaged by removing and / or inserting cards, modules
or inter connecting while this unit is energized.
Primary Power source (AC) and Earth Ground Connection:
AC Power connections are made inside the control panel cabinet. A separate Earth Ground connection must be
