INS627-8 26/44
Tamper Relay Negative Removed on Tamper Input*
Fault Relay Reports Faults from the sounder*
N Not applicable to Odyssey X-E & X-BE
Although the unit has been designed to be compatible with a wide range of
control panels, for optimum performance, it is highly recommended that the unit
should be used with Texecom's range of control panels.
For safety reasons, each Texecom sounder and strobe unit incorporates a unique
patented engineer Hold‑Off mode. This mode prevents the unit from self-activating
during installation and maintenance, thereby allowing only bona fide engineers
access to the unit without any loss of tamper protection.
When connecting the unit to the control panel, it is recommended that wiring
should be connected to the unit first and the control panel second. The unit
should then be initially powered from the control panel. If the tamper circuit is
open the siren will sound for 5 seconds after which it will automatically enter Hold-
Off mode and disable Self-Activate (S/A) on tamper. This will prevent the unit from
self-activating as long as the tamper circuit remains open. An open tamper circuit
is indicated by only the left‑hand side LED flashing. Connect the battery either
using the jumper included on some models or by moving the red battery wire from
the “N/C” (No Connect) terminal to the “Battery +” terminal. Fit the outer cover
and secure with the M6 screw(s) provided.
When the outer cover is replaced and the tamper circuit is closed, the LEDs will
alternate rapidly, confirming that the tamper circuit is secure and signalling that
S/A on tamper will be re-enabled within 2 minutes, after which the LEDs will
alternate slowly to signal normal operation. If the tamper circuit is re-opened
within the 2 minute period, then Hold-Off mode will be restored.
N If the unit is powered up with the tamper circuit closed it will NOT sound for 5
seconds and will NOT enter Hold-Off mode. In order to disable the S/A function,
before the cover is removed, Hold-Off mode should be invoked as for servicing
(see chapter 2.0)
N For safety reasons the strobe is disabled during Hold-Off mode.
