SELF-POWERED SIREN
EAS-202

You can select two audible signals for each Alarm Input- with
the exception of the Internal Tamper Input which has only one
audible signal (up-scale modulated frequency between 800
and 2000 Hz)
The audible signals and modulated frequency range can be
found in the "PROGRAMMING" section.
There are two frequency ranges: 800/2000 Hz and 1100/2400
Hz.
The audible signalling will stop as soon as the maximum Alarm
Time expires, whereas, the visual signalling will continue until
the Alarm conditions clear (Memory Flashing).
The Memory and Alarm flash sequences (Flasher bulb ONLY)
are as follows:
ON (ms) OFF (ms)
Alarm flashing 250 750
Memory flashing 250 1500
Under low battery conditions, this SIREN will bypass the
strobe / flasher and use the residual charge to power the hom
-- this status will be signalled on terminal [G].

standby status) will disconnect in the event of low battery or damage to the hom or flasher bulb.
If you remove the on-board Jumper [G] (inserted at factory) Alarm signalling will be inhibited, and only
Trouble conditions will be signalled.
Flasher trouble -- the horn will sound twice
Horn trouble -- the flasher will blink twice
Battery trouble -- the horn will sound once and the flasher will blink once
No trouble (OK!) -- the horn will sound twice and the flasher will blink twice
The signals will be repeated every 4 seconds until the Jumper is reinserted,
This SIREN will accept a maximum of 6 Alarm signals in 4 minutes after which, it will block the horn for 4
minutes. This process will protect the SIREN against persistent Alarms generated by the Control panel.
ALARM PRIORITY
This SIREN priodty is as follows:
Alarm signals triggered by the Tamper device will overrideAlarm signals triggered by terminals [+N] and [A].
Alarm signals triggered by terminal [+N] will override Alarm signals from terminal [A].
Override will generate a variation in the audible signal.

TAMPER PROTECTION
The Tamper device (to be anchored to the wall) will trigger Alarms when either the frontplate or innerplate is
removed, or when this SIREN is pulled from the wall (Snatch Tamper). If you setup this SIREN to operate in
Automatic mode, Tamper signalling will cease 40 seconds after the Alarm conditions clear, or after a
maximum of 10 minutes (maximum Alarm time).
This SIREN can operate in Normal or Automatic mode. In both modes, the [AS] and [ASG] terminals will
open in the event of Tamper, thus signalling the condition to the Control panel. If you setup this SIREN to
operate in Automatic mode, it must be the last peripheral device on the Control panel Tamper line, as the
[ASG] terminal is closed to negative and cannot be utilized. In Automatic mode, audible and visual signalling
will be activated automatically by this SIREN (see fig. 3a-b-d). In Normal mode, audible and visual signalling
will not be activated automatically (see fig. 3c),
ACTIVATION
This SIREN can be activated by the Tamper device, and
by signals from terminals [+N] and [A].
For example: this SIREN will activate when the voltage
fails on terminal [+N].
This process will allow the SIREN to detect wire cutting,
as this Input also supplies the power and battery charge.
Input Terminal [A] (with programmable polarity) can be
used for connection to other devices.
SIGNALLING
The audible and visual signals on the horn and strobe /
flasher depend on the type of Alarm, and the Alarm signal
configuration.
The sound modulation extremes generate a fastidious
shrill tone -- intended to discourage intruders, and a low
tone -- to ensure good audibility.

- Magneto dynamic exponential horn connection terminals
- Voltage (positive) and alarm terminal. 13.8V should be applied to this terminal for the battery
charge. If this voltage fails (wire cutting or alarm) the SIREN will go into alarm status
- Negative supply terminal and ground of the internal circuit
- Alarm activation terminal with programmable polarity
- Trouble signal terminal for: low battery or battery trouble conditions; horn trouble; fasher
bulb damage (Strobe board NOT PRESENT), Normally closed to negative. This terminal
will open in the event of trouble.
- Tamper: these terminals will open when the cover or innerplate is removed. Or when
SIREN is pulled from the well (for normal mode ONLY)
TERMINALS DESCRIPTION
The Alarm Time will be counted from activation of the horn and strobe/flasher.
When the maximum Alarm Time of the higher priority Alarm expires, or when the Alarm conditions clear, the
lower Drioritv Alarm sianal will activate the horn and strobe/flasher in accordance with its configuration.
If a pdority Alarm signal overrides an Alarm that has been running for more than 30 seconds, the maximum
Alarm Time of the interrupted signal will RUN ON.
If the pdority Alarm terminates (due to Timeout or Restoral) before the maximum Alarm Time of the
interrupted signal expires, the latter will activate the horn and strobe/flasher for the residual time.
If a pdority Alarm signal overrides an Alarm that has been running for less than 30 seconds, the maximum
Alarm Time of the interrupted signal will FREEZE.
If the interrupted Alarm signal is still present when the priority Alarm terminates (due to Timeout or Restoral),
it will activate the horn and strobe/flasher in accordance with its configuration.
If the interrupted Alarm signal has restored when the priority Alarm terminates (due to Timeout or Restoral),
it will activate the horn and strobe/flasher for 30 seconds.
Table 2 shows how the lower pdority Alarm signal [A] will activate the horn and strobe/flasher after the
higher pdority Alarm (Alarm signal [+N]) has been executed.
Memory flashing will stop (after the maximum Alarm-Time) when all the signals, that triggered the Alarm,
restore to standby for 5 seconds (Restoral Time). Internal Tamper Restoral requires 40 seconds.
PROGRAMMING
The board Jumpers (Wire and Link) are already connected (see fig. 2).
If you are installing several SIRENS Hornstrobes in the same area, the Jumper Wires will allow you to select
a different sound for each one, thus permitting Users to distinguish between them.
You can also select different sounds for different Alarm types (gas leak, burglary, flooding, etc.) Or locations
(office, warehouse, garage, etc.)
This feature will allow users to recognize the Alarm type and its location.
The wire Jumpers (+N and S) will allow you to select the sounds for Inputs [+N] and [A], respectively. These
Jumpers will also allow you to set the maximum Alarm Time for Internal tamper.
For the various programming options provides by the Wire and Link Jumpers refer to Table 2.
For the frequency profile of the audible signals refer to Table 3.
INSTALLATION
This SIREN should be mounted as high up as possible on a flat wall, as uneven surfaces may jeopardize
proper functioning of the Snatch protection.
1. Using the Drilling pattern, mark the screw location (5 and 12) then ddll the anchor screw holes.
NOTE: The screw locations on the pattern correspond to the anchor screw holes on the backplate.
2. Pull the wires through the cable entry (16).
3. Secure the backplate and Snatch device to the wall.
WARNING: Do not over tighten the snatch bracket screw (12) as this may damage the bracket wings (see
figure 1 ).
4. Complete the connections on the terminal board (10) as per the instruction in the relevant paragraph.
5. Mount the battery on its support (6) and complete the battery connections (see figure 1).
At this point the flasher/strobe will flash, as per Memory flashing (Installation phase).
This status wilt be held until internal Tamper ends (i.e. until the Metal Innerplate and Cover are secured).
Once terminated, a 20 second Startup phase will begin (signalled by fast flashing).
If internal tamper occurs during this phase this SIREN will go back to the installation phase.
If 13.8 V is applied to terminal [+N], after the Startup phase, this SIREN will be operative.
Otherwise, it will enter the Wait phase, which will be held until 13.8 V is applied to terminal [+N], or until
Internal Tamper occurs.
In the latter case this SIREN will go back to the installation phase.
Once the Wait phase terminates, the 20 second Startup phase will begin, after which, installation will be
complete.
If Internal Tamper occurs during the Startup phase, this SIREN will go back to the Installation phase,
however, if the 13.8 V fails on terminal [+N] this SIREN will go back to the Wait phase.

Fig. 3 - a) Automatic mode with 10 min. max alarm-time;
b) Automatic mode with 3 rain. max. Alarm-time;

D) Automatic mode with Awith Negative polarity (relay output programmed as Normally Closed
Associated with the required event).
This installation process will allow you to mount this SIREN and connect it (via terminal [+N]) to the 13.8 V
of the Control panel when you are ready.
The flasher/strobe will not function during the Wait phase, and therefore, use of the battery will be reduced
to a minimum.
WARNING: If you are fitting or removing the metal innerplate while the flasher is active, DO NOT allow it to
come into contact with the flasher terminals, as this may cause a short-circuit.
CONNECTIONS
Use shielded cable only, with one end connected to the Control panel Negative and the other left free.
The Control panel Alarm Output can be connected to either the [+N] or [A] terminal (with programmable
polarity). In I~th cases, 13.8 V (min. 0.6 A) must be applied across the [+N] terminal and Negative.
This voltage is necessary for the battery charge and Wire cutting protection.
Some Control panels have a custom [+N] terminal for the connection to the SIREN [+N] terminal, see fig.3a.
The 13.8 V, present on the custom [+N] terminal during Standby status, will fail if the Control panel
generates an Alarm.
If the Control panel you are using does not have such a terminal, you can use the free voltage Alarm relay
changeover contacts, as per fig 3b.
In figures 3a and 3b the [AS] jumper is inserted (Automatic mode). Therefore, in the event of internal Tamper,
this SIREN will go into Alarm status, regardless of the status of terminals [A] and [+N].
The Alarm will end 40 seconds after Tamper restoral or when the maximum Alarm time expires. In the latter
case, the flasher will continue to signal.
If you apply the Alarm signal to the [A] terminal with programmable polarity, you should connect it to a
Control panel terminal that closes with compatible polarity in the event of an Alarm (see fig. 3d).
Fig. 3(; shows a connection using the [AS] terminals of this SIREN.
These terminals, and the [A.S.] terminals of the detector in the wiring diagram, will be short-circuited during
standby status.
If Ihe SIREN detects Tamper, or the [A.S.] terminals of the Detector open, an Alarm signal will be present on
the [AS] terminals of the Control panel.
However, neither the horn or strobe/flasher will activate, because the AS jumper is not connected (AS mode).
Figure 3d shows an application using the [A] Input with Negative polarity.
The common contact [C] of the relay is connected to the [A] terminal with Negative polarity.
Under standby conditions, this terminal will be shorted to the [NC] terminal, and therefore, connected to
Negative.
Under Alarm conditions, the relay will switch the [C] contact to [NA], connecting +12V to the [A] Input of this
SIREN, thus generating an alarm.
