1 Introduction
Glass break detector «Zvon-1» ver. 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» contacts opening;
- generates tamper message by «TAMP» contacts opening;
- possibility of wall or ceiling installation, as well as installation at
partition between secured glass and a curtain.

Installation Guide
Figure 2 – The Detector without Cover
PCB comprises marked terminals (11) for connection with control
panel, anti tamper switch (4), three LED indicators (8), microphone (10)
and jumpers (7) for the Detector adjustment.
6.2 For the Detector installation act as follows:
- insert a flat screwdriver into the slot at the side wall of the cover,
push the latch (5) 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 (12) 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 «Normal» mode
is fulfilled by MODE jumper installation (see Table 3) or in 15 min
automatically.
For monitoring the Detector availability, it is allowed to use electronic
glass break simulator during adjustment.

- 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 10 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 (9) and
a latch (5). The base design includes openable holes (12) for wiring
and a hole (2) for fastening a base to the mounting surface. PCB is
fastened to the base by lugs (9) and screw (6).
