3. GENERAL DESCRIPTION

The heat detectors are conventional xed temperature heat detectors. The detectors will give an alarm at a certain xed tempera-

ture (57 °C / 72 °C / 87 °C / 117 °C).

The detector is intended for outdoor use or indoor use in high humidity premises.

3.1. DETECTOR

The sensing element is a heat pick-up shield and a bimetal switch.

The detectors will give an alarm within a response temperature range in accordance with EN54-5, see table below.

Type Static response temperature Category

6295 57 °C A2 S

6296 72 °C B S

6297 87 °C C S

9298 117 °C E S

3.1.1. LATCHING

The detector is latching. The detector will not be automatically reset if the temperature, after the alarm, falls below the detector's

static response temperature. The detector's LED and a connected external LED will be lit until the detector is reset via the CIE.

6295-6298 ENCLOSED HEAT DETECTOR - FIRE ALARM SOLUTIONS TECHNICAL DESCRIPTION

3.1.2. EXTERNAL LED

One External Indicator (LED) can be connected to the screw terminals E+ and E-:

• E+ Ext. LED, for example Ext. indicator 2218; J2:2 (+)

• E- Ext. LED, for example Ext. indicator 2218; J2:3 (-)

Do not connect an external indicator (LED) to terminals (E+, E-) when the detector is used as intrinsically

safe detector in hazardous (Ex) areas, see 5.2. INTRINSICALLY SAFE INSTALLATION (6295-6296)

on page 9.

3.2. CONNECTION BOX

The connection box is prepared for required number of compression glands, one, two, or three.

3.3. ZONE LINE INPUT

The conventional detector is connected to a zone line input (for conventional detectors) in the CIE The last unit on the zone line has

an End-of-line device to be connected. The type of end-of-line device is depending on the CIE and the type of zone line input.

6295-6298 ENCLOSED HEAT DETECTOR - FIRE ALARM SOLUTIONS TECHNICAL DESCRIPTION

4. MOUNTING

The connection box must be mounted in the ceiling. Screws are not supplied.

(Measure in mm)

a) Cut out the required number of knockouts and apply the compression glands. Tighten the compression glands rmly.

b) Mount the connection box in the ceiling.

c) Insert the cables in the compression glands.

If the outer cable diameter is < 6 mm, insert the enclosed rubber tube before installation of the cable. If the

outer cable diameter is ≥ 6 mm, do not use the enclosed rubber tube.

d) Tighten all compression glands with 4 Nm or more.

e) Connect the wires from the CIE to the A and B push-on connectors.

f) Connect the next unit or the end-of-line device to the other pair of A and B push-on connectors.

g) Mount the detector on the connection box with the two enclosed screws. Tighten the screws rmly with 1.4 Nm or more.

5.2. INTRINSICALLY SAFE INSTALLATION (6295-6296)

Screen wire termination is not provided.

If cable screen is used, it should be connected to the closest earth point (protective earth) outside the

hazardous (Ex) area and should be capable of withstanding a test voltage (500 V AC) for one minute.

Do not clean by rubbing or with solvents to avoid electrostatic hazard.

Do not install in a continuous dust ow to avoid propagating brush discharges.

End-of-line device

Alternative A:

The conventional IS detectors are connected via a galvanic

isolator / barrier unit to an expansion board 4580 zone line

input.

The zone line input is programmed as:

Ex zone line input (EOL resistor).

End-of-line resistor 10K.

Alternative B:

The conventional IS detectors are connected via a galvanic

isolator / barrier unit to an addressable isolated zone

interface 2822 that is connected to an I/O unit 4461 zone line

input.

The I/O unit 4461 require an Addressable Isolated zone

interface 2822 with PCB 2823 revision ≥ 2.

End-of-line resistor 8K2 is supplied with 2822.

6295-6298 ENCLOSED HEAT DETECTOR - FIRE ALARM SOLUTIONS TECHNICAL DESCRIPTION

Channel: Maximum 5 units on the Zone line (Channel), Cable FKAR-PG 2x0.5 mm², blue

(with aluminum polyester foil shield + tinned copper drain wire 1 mm² is normally not used/connected)

Zone: EKKR / ELQRB 2x0.6 mm (0.3 mm²) Connection of alarm points is not allowed on this line.
