
Verify that the control unit can only be accessed by authorised qualified
persons accessible and that it is protected against unauthorised contact.

Verify that the audible alarm signal of the control unit can always be
heard, even in the case of ambient noise.
If audibility cannot be ensured, you must install an additional alarm unit at a
suitable location in the building (for example, additional alarm unit ZAG 01,
horn KH 1 or combined alarm light and horn from AFRISO). In this case, it is
recommended to use the operating mode "FailSafe" (see "Setting the oper-
ating mode").
5.1 Preparing mounting
Note the information on the requirements concerning the
interstitial space and the leakage containment.
This information can be found at the end of these operat-
ing instructions in the chapters "Additional requirements
and information".
5.2 Mounting the photoelectric probe

Verify that the probe is submerged even in the case of small amounts of
liquid.

Verify that the tip of the probe is not subjected to mechanical load.
1. Mount the probe at the lowest point of the area to be monitored (lying or
suspended).
- Do not suspend the probe directly from the control unit.
2. Use the holder supplied with the product to provide strain relief for fasten-
ing.
3. Place the probe at a position where there is little or no influencing light.
