MOUNTING PROCEDURES:
Use this mounting procedure to position the field wires in the backbox so that they use minimum space and produce minimum
stress on the product. This is especially important for stiff, heavy gauge wires and wires with thick insulation or sheathing.
1. Connect field wires to the HS-24 terminal block (polarity must be observed).
2. Bend the field wires up 90° at the connection to the terminal block.
3. Carefully push the field wires into the backbox by hand.
4. Carefully press the HS-24 to the backbox, verifying that the HS-24 is seated and aligned correctly.
5. Screw the HS-24 to the backbox using the screws supplied. Refer to Mounting Options for screw size.
MOUNTING NOTES:
CAUTION: Check that the installed product will have sufficient clearance and wiring room prior to installing backboxes
and conduit, especially if sheathed multiconductor cable or 3/4" conduit fittings are used.
1. Conduit entrances to the backbox should be selected to provide sufficient wiring clearance for the installed product.
2. When terminating field wires, do not use more lead length than required. Excess lead length could result in insufficient
wiring space for the signaling appliance.
3. Do not pass additional wires (used for other than the signaling appliance) through the backbox. Such additional wires could
result in insufficient wiring space for the signaling appliance.
CAUTION: If these appliances are operated within 15 inches of a person's ear, they can produce a sound pressure level that
exceeds the maximum 120dBA permitted by ADA and OSHA rules. Exposure to such sound levels can result in damage to a
person's hearing.
This appliance can produce a distinctive three pulse Temporal Pattern Fire Alarm Evacuation Signal (for total evacuation) in
accordance with NFPA 72.
CAUTION: Check the installation instructions of the manufacturers of other equipment used in the system for any
guidelines or restrictions on wiring and/or locating Notification Appliance Circuits (NAC) and notification appliances. Some
system communication circuits and/or audio circuits, for example, may require special precautions to assure electrical noise
immunity (e.g. audio crosstalk).
NOTE: This equipment has been tested and found to comply with the limits for a Class B digital appliance, pursuant to Part 15
of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in residential
installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance
with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference
will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception,
which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or
more of the following measures: 1) Reorient or relocate the receiving antenna, 2) Increase the separation between the equipment
and receiver, 3) Connect the equipment into an outlet on a circuit different from that to which the receiver is connected, and 4)
Consult the dealer or an experienced radio/TV technician for help.
