PERATION
The Vertec 3000 is used for notification of an alarm condition as generated within an intruder, hold-up or other alarm
system. In response to commands from the alarm system control panel, the sounder
will emit a high intensity sound
and/or operate a visual flash.
The sounder
will detect any attempt to gain unauthorised access to the sounder by removal of the cover, or any attempt
to remove it away from its mounting surface. This will generate a tamper signal which is normally fed back to the alarm
control panel. Integrity of the Trigger Command (Ring Line) connection is constantly monitored and will cause the unit to
self activate if loss of connection is detected.
These sounders are classified as self powered sounders and have an on-board battery which is recharged via the external
power source. This battery is used to operate the sounder if the external power is removed. The sounders
will self actuate
in the event that a tamper condition is detected or the external power to the sounder is removed.
Every 24 hours the sounder performs a self test to check the integrity of its on-board battery, its battery charging circuit
and its piezo transducers. If an error condition is detected, a fault signal is generated. This is normally connected back to
the control panel. This self-test can be triggered at any time by a Remote Test command sent from the control panel.
To assist with commissioning, the sounders have an Engineer Mode to provide silent start-up and Tamper Tones that
indicate the correct closure of the tamper detection switches.
Two Comfort LEDs are used to provide a heart-beat type visual indication when the sounder is not sounding. These may
be disabled.

NFORMATION
Tamper Circuit for Single or Multiple Cascade Installations
For a single siren installation, link TS to H- and connect TR to the control panel Tamper return input. In cascade
installations with two or more sounders, the TS (Tamper Source) will normally be connected to the TR (Tamper Return) of
the next sounder, except for the last unit which will have TS linked to H- .
Engineer Mode
This selects silent start-up and silent maintenance. The ENG input may be brought back to the control panel and
connected to a programmable output. Switching this control panel output high when maintenance is required will prevent
the sounder from self activating when the cover is removed or R- activated. The Tamper output is open when ENG is high;
this prevents inadvertent system setting with the sounder left in Engineer Mode.
Self Test and Fault Output
The sounder performs a self test every 24 hours. This function tests the condition of the battery and piezo sounders. If a
fault is found the Healthy/Fault output will open.
The Fault output will be cleared (output closed) when:
- the fault has been cleared, e.g. battery (re)connection
- the fault has been cleared and the sounder performs its next 24hour self test
- the fault has been cleared and a self test is triggered using the Engineering Remote Test input
- the fault has been cleared and the sounder has been disconnected from H+ AND the SAB battery has been disconnected
(hardware reset)
Remote Test
Taking the Engineer/Remote Test input high will force a self test. The Healthy/Fault output is immediately opened to
acknowledge receipt of the Remote Test instruction. The condition of the piezos and battery is immediately tested. Any
fault found will be indicated by the Healthy/Fault output remaining open after 10s. The Healthy/Fault output will remain
open until the fault has been cleared and another Self Test or Remote Test has been performed. If the self test has passed,
the Healthy/Fault output will close after 10s of starting the Remote Test.
