GENERAL DESCRIPTION
The manual call point
P445
is used to manually
initiate an alarm condition on conventional fire
prevention systems.
The
P445
is a frangible element type: by
pressing on the operating face of the manual call
point, the frangible element breaks and the
alarm signal will be activated. The red LED
indication indicates, when turned-on, the alarm
condition.
To reset it is necessary to open the manual call
point and replace the frangible element.
To open the enclosure use the key as shown in
Fig. 1.
The 80SB7410121 counter-base can be used
for installations with external electrical conduits
with a diameter of up to 20mm.
The manual call point
P445
is to be used with
actual (C7000, C7000R, C54) and future Elkron
conventional control panels.

CONNECTIONS
A shielded cable must be used
: connect the
shield of the cable to the ground in the control
panel only and connect the shield between a
device.
The section of leads can vary according to the
length of the detection line.
A lead section of 1.5 mm
2
is advised.
Don’t use cable that exceed these limits:
Maximum resistance
= 100 Ω
Maximum capacitance = 2 µF
The electrical connection must be performed by
removing approximately 10 mm of insulating
cover from the main lead and insert it on the
terminal block.

JP1 must be only executed with conventional
control panels that are able to recognize manual
call points from detectors on the same circuit.
