Limited Warranty
Digital Security Controls Ltd. warrants that for a period of twelve months from the date of purchase, the
product shall be free of defects in materials and workmanship under normal use and that in fulfillment of any
breach of such warranty, Digital Security Controls Ltd. shall, at its option, repair or replace the defective

workmanship and not to damage incurred in shipping or handling, or damage due to causes beyond the con-
trol of Digital Security Controls Ltd. such as lightning, excessive voltage, mechanical shock, water damage,
or damage arising out of abuse, alteration or improper application of the equipment.
The foregoing warranty shall apply only to the original buyer, and is and shall be in lieu of any and all other
warranties, whether expressed or implied and of all other obligations or liabilities on the part of Digital Secu-
rity Controls Ltd. Digital Security Controls Ltd. neither assumes responsibility nor authorizes any other per-
son purporting to act on its behalf to modify or to change this warranty, nor to assume for it any other
warranty or liability concerning this product.

Smoke Detectors: Smoke detectors that are a part of this system may not properly alert occupants of a fire
for a number of reasons, some of which follow. The smoke detectors may have been improperly installed or
positioned. Smoke may not be able to reach the smoke detectors, such as when the fire is in a chimney, walls
or roofs, or on the other side of closed doors. Smoke detectors may not detect smoke from fires on another
level of the residence or building.
Every fire is different in the amount of smoke produced and the rate of burning. Smoke detectors cannot
sense all types of fires equally well. Smoke detectors may not provide timely warning of fires caused by care-
lessness or safety hazards such as smoking in bed, violent explosions, escaping gas, improper storage of flam-
mable materials, overloaded electrical circuits, children playing with matches or arson.
Even if the smoke detector operates as intended, there may be circumstances when there is insufficient warn-
ing to allow all occupants to escape in time to avoid injury or death.
Warning: Digital Security Controls Ltd. recommends that the entire system be completely tested on a regu-
lar basis. However, despite frequent testing, and due to, but not limited to, criminal tampering or electrical
disruption, it is possible for this product to fail to perform as expected.
Important Information: Changes or modifications not expressly approved by Digital Security Controls
Ltd. could void the user's authority to operate this equipment.
