IGNIS - Conventional 4 wire Heat Detector
Product Description: Conventional 4 wire Heat detector IGNIS
is a thermal heat detector that uses a static heat element of 57
°C. It is designed to respond when theconvictedthermal
energyof a fire increases the temperature of a heat sensitive
element.
Thethermal massand conductivity of the element regulate the
rate flow of heat into the element. Heat detectoroperate when
the heat sensitiveeutectic alloyreaches the eutectic point
changing state from a solid to a liquid. Thermal lag delays the
accumulation of heat at the sensitive element so that a
fixed-temperature device will reach itsoperating
temperaturesometime after the surrounding air temperature
exceeds that temperature.
The range of bases allows adapting the entire line of IGNIS
detectors to the different installation needs. Its ample interior
space makes mounting and electrical connection easier. Its
special double-sided nickel-plated phosphor bronze terminals
guarantee an optimal and reliable long-term contact with the
detector.

User Manual
Warranty
We warranty its enclosed detector to be free from defects in
materials and workmanship under normal use and product
warranty of 12 months from the date of supply.
No agent, representative, dealer, or employee of the
company has the authority to increase or alter the
obligations or limitations of this warranty.
Warning/Caution
●Install and use equipment in accordance with
installation instructions manual.
●Do not Paint the Detector.
●Dust cover must be removed before
commissioning to avoid detector contamination.
●During maintenance, do not remove the detector
before notifying proper authority.
Maintenance
Before cleaning, disable the system to prevent false alarms
and inform proper authority.
1. Remove the detector to be cleaned from the
system.
2. Gently remove the back plate and PCB from the
sensor chamber.
3. Use a blower to clean the sensor.
4. Re-insert the PCB & back plate properly.
5. Fit the detector head with the base of the detector.
NOTE: Strictly maintenance to be done by a technically
trained person.
Installation Procedure:
Note: Before Installation, this manual should be available with
the user of this equipment.
1. IGNIS detectors are intended for mounting on a
ceiling or a wall in accordance with requirements.
2. Fit the mounting base to the electrical junction box
with the given screws. If a high profile base is used,
then a junction box is not required. (High profile base
directly comes up as a built-in junction box.)
3. Connect ZONE ‘+’ & ‘- ‘to the mounting base pin 1 and
3 respectively (Refer connection diag.)
4. Align detector head notch with mounting base notch
as shown in fig.
5. Push the detector head into the base and turn
clockwise to secure it in place.
