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

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 override Alarm 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.
