Rielta ZVON-1 Installation Manual

1 Introduction

Glass break detector «Zvon-1» (hereinafter, the Detector) is designed
to provide the following tasks performance:
- detecting destruction of construction glass: common and laminated
with polymer film, installed in structural units (openings) and/or interior
elements of closed spaces;
- generates alarm messages by alarm loop contacts opening;
- operation in condition of installation on wall, ceiling or on a pier
between the monitored glass and curtains.

5 Choosing the Detector Location

Before installing the Detector, get acquainted with the following
requirements:
- it is recommended to install the Detector at least 2 m height (see
examples of installation in Figures 3 – 6);
- during joint operation with an active ultrasonic Detector, distance
between Detectors must be not less than 1 m;
- the entire surface of the monitored glass should be available within
the direct visibility of the Detector;
- distance (L) between the Detector and the farthest point of the
monitored glass should not exceed 6 m;
- the Detector operation mode is set in accordance with Table 3.

6 Installing the Detector

6.1 The Detector comprises cover and base (1) with installed printed
circuit board (PCB) (3). Cover is fixed on a base by two lugs (8) and
a latch (4). The base design includes openable holes (11) for wiring
and a hole (2) for fastening a base to the mounting surface. PCB is
fastened to the base by lugs (8) and screw (5).

push the latch (4) and put off the cover;
- fasten the base with the PCB by the screw to the mounting surface
at the chosen place of installation;
- open the necessary quantity oh holes (11) in the sidewall of the
*
base, insert and pull wires through them;
- connect the Detector to the control panel in accordance with it's
*
manual.

7 Switching ON and Adjustment

Install jumpers MODE and IND, remove SENS jumper.
Energize the Detector. At this moment red LED indicator should light
up for 3 sec and get out, what is indicating the Detector turnover to
standby mode. If indication displays interferences presence, eliminate
it cause if possible.
Fulfill the Detector adjustment as follows:
- remove the MODE jumper (mode «Adjustment»);
- suspend a steel ball 21 – 22 mm in diameter on a 35 cm long
thread near the farthest part of the monitored glass, deflect it at an
angle of 30 – 70° (see Table 4). Deliver a blow to the most distant place
of the secured glass. If red indicator is not lighting after test blows, the
Detector sensitivity should be increased by installation of SENS jumper;
- check adjustment correctness of the Detector with the closed cover.
Changeover of the Detector from «Adjustment» to «Standby» mode
is fulfilled by MODE jumper installation (see Table 3) or in 15 min
automatically.
