8.0 Hold-Off Mode
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. The sounder can be put in
hold-off mode by flashing the strobe 3 times, or by pressing the Omit key when in
Bell Test menu.
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
self activation 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
The LED's will only flash after hold off mode has stopped IF the LED jumper is
in the "ON" position.
N
The strobe is disabled during hold-off mode. Hold-off mode is immediately
cancelled when the sounder is activated from the control panel if the tamper is
closed.
