Palex 620 User manual

HEAT DETECTOR Model No. 620
Description
The Conventional Photo–electronic heat detector uses a state
of-the-art optical sensing chamber. This detector is designed to
provide open area protection and to be used with most
conventional fire alarm panel.
The Conventional rate of rise heat detector uses thermal
component to detect the temperature changing in the
environment. It can enable fire alarm when the temperature
difference achieved the setting rate of rise temperature value,
reach the setting fixed value. It has a stable and reliable working
performance.
Two LEDs on each detector provide local 360 visible alarm
Indication. They flash every six seconds indicating that power
Is applied and the detector is working properly. The LEDs latch
On in alarm. LEDs will be off when a trouble condition exists
That the detector sensitivity is outside the listed limit. The alarm
Can be reset only by a momentary power interruption.
The detector that initiated the alarm condition will have its red
LED and relays latched until reset by panel.
Features
 Advanced algorithms provide advanced
detection discrimination
 Dual LED for 360 degree visibility
 High immunity against unwanted alarms
 Stable optical smoke sensing chamber. No
adjustment or replacement required
 Easy installation
 Replacement required
 2 wire based detector
 Low maintenance
INSTALLATION
Note : All wiring must conform to applicable local codes,
Ordinances and regulations.

INSTALL THE DETECTOR BASE
1. Open area smoke or heat detectors are
Intended for mounting on a ceiling or a
Wall in accordance with the fire standard
In your country.
2. Attach mounting base to ceiling or wall. The
base of the detector can be mounted
directly onto an electrical junction box such
a an octagonal (75mm, 90mm or 100mm) a
round (75mm), or a square (100mm) box
without using any type of mechanical
adapter.
3. Position all wires flat against terminals, and
fasten the wires on the terminals, See
Figure a.
4. Terminals functions description :
Terminal 2: IN+(Zone Input+) Terminal 6: IN+(Zone Output+) Terminal 6: Remote Indicator+
Terminal 5: IN- (Zone Input-) Terminal 5: IN-(Zone Output-) Terminal 3: Remote Indicator-
INSTALL THE DETECTOR HEAD
1. Align detector head alignment mark line
with the base’s start alignment mark line as
shown in Figure 2
2. Push the detector head into the base while
turning it clockwise to secure it in place.
3. Do not install the detector head until the
area is thoroughly cleaned of construction
debris, dusts, etc.
4. After all detectors have been installed,
apply power to the control panel.
5. Test the detector(s) as described in the
TESTING section of this manual.
6. Notify the proper authorities that the system
is in operation.
