Once all testing has been carried out on the cabling and
continuity & insulation
has been proven, the Multipoint
unit may be assembled.
Before installing the head remember to note the serial number of the device (located on the electronics module) on
to your drawings or configuration sheets to enable you to prove its location later. The address allocation for the
device is carried out automatically by the control panel whilst in initialisation mode, so addresses do not need to be
set manually. See the system Installation and Operating Instructions for further details.
The Multipoint unit may then be assembled. To insert the Electronics Module, locate the pins and gently push it
home.
The Optical Chamber may then be fitted. Locate the plastic guides into the base and gently twist clockwise until the
unit locks in place. Remember not to force this item: if the Electronics Module is correctly located then the Optical
Chamber should locate with very little force. The Optical Chamber may be removed with the Head Removal Tool.
Tamper Resistance and Head Removal
The Multipoint detector incorporates a tamper resistant locking mechanism that
prevents its removal from the base without the use of a special tool. To remove
the device the tool should be attached over the detector and turned anti-clockwise
allowing the detector to be removed from the base.
If required the Electronics Module may be removed
by inserting the key into the triangular slot adjacent
to the LED and then pulling to ease the Module out.
Do not pull on the optical transmitter and receiver
pair as you may misalign them.
Device Settings
The detection and sounder modes may be configured using the relevant panel software configuration package.
Type
Description
Detection Off:
OFF
No smoke or heat detection
Smoke Modes:
SM1
Highly thermally enhanced optical detector. Used where ionization detectors are normally fitted,
especially where there are high ceilings or a risk of free burning fires.
SM2
Thermally enhanced optical. General purpose smoke detector, to be used where optical detectors are
normally fitted, where there is a risk of a smouldering fire and for escape routes.
SM3
Thermally enhanced optical with smoke pulse rejection. Used where optical detectors are normally
used in positions exposed to brief concentrations of water vapour or smoke e.g. from a bathroom,
kettle, etc.
Heat Modes:
HM1
Rate of rise to 58
o
C. Used where a standard rate of rise detector would be fitted, e.g. not kitchens.
HM2
Low fixed temperature 58
o
C. Used where a standard fixed temperature heat detector would normally
be fitted, e.g. suitable for domestic kitchens, etc.
HM3
High fixed temperature 90
o
C. Used where a high fixed temperature heat detector would normally be
fitted, e.g. suitable for boiler rooms, commercial kitchens, etc.
