NSC Sicherheitstechnik B02725-00 Discovery Manual Call Point
Unfortunately, we no longer supply products by NSC. Please visit the Fire Extinguishing section for alternative options.
Based on the KAC conventional MCP range, NSC Sicherheitstechnik have designed the Discovery Manual Call Point and made it EN54Ė11:2001 compliant and both electronically and mechanically
compatible with previous Apollo call
points that were based on KACís World Series
The address of each call point is set at
the commissioning stage by means of a
seven-segment DIL switch.
If an MCP is activated, it interrupts the
normal protocol to give a fast response.
A single bi-coloured alarm LED is provided
on the call point. This LED is controlled,
independently of the call point, by the
control panel and may be set to flash each
time the call point is polled. The red LED
is lit when the call point has been activated
and sent into alarm. On the isolated
versions an amber/yellow LED indicates
a short circuit on the loop wiring either
side of the call point.
Call points can be remotely tested from
the panel by transmission of a single bit
in the communications protocol. Call points respond by providing a value of
64 which corresponds to the alarm value.
The panel should recognise this response
as a test signal and should not raise a
Discovery Manual Call Points are available
with or without an isolator. Each version
is available with a resettable element
and a backbox for surface mounting as
standard. If a glass option is required,
spare glasses are available on request.
For ease of installation Discovery manual
call points are supplied with clip-on
terminal blocks and a connector which
allows continuity testing before call points
To provide additional protection against
accidental operation, a transparent hinged
cover with a locking tag, part number
26729-152 is available, which can be
fitted to the manual call point. Please
note that the call point does not conform
to EN54-11:2001 when this lid is fitted and
secured with the locking tag.
