en | Notices Long-range Beam Smoke Detectors Notices 1 Before installing the module, become familiar with the Installation and Operation Guide for the control panel you are using. Caution! When power is removed and reapplied to the receiver, such as in a power outage and restoral ! or an alarm reset, an internal setup procedure is initiated and can last from 1 min to 2 min. During this period, the detector is not able to initiate signals.
Long-range Beam Smoke Detectors – Notices | en 5 A D306 Remote Indicator Plate, a D1005 Test Cable, and a set of four plastic sensitivity test filters are included with each detector. – A D307 Remote Test and Indicator Plate (not supplied) is required for remote alarm testing. 2.2 – A D308 Test Kit (not supplied) is needed for field testing. – A D309 Alignment Light is also available to aid in transmitter/receiver alignment.
en | Notices Long-range Beam Smoke Detectors Figure 2.3: Beam Blockage 1 Transmitter 3 Blocking object 2 Beam 4 Receiver The receiver automatically compensates for the gradual signal loss because of dust and dirt buildup on the cover. After a signal loss of 50%, the receiver indicates a trouble. When the built‑up dust and dirt are cleaned or the blockage is removed, the detector automatically returns to its normal operation level.
Long-range Beam Smoke Detectors 3.2 Notices | en 7 Avoid bright light sources Bright light can cause stray signals. Do not point the receiver toward any of the following sources. Sunlight: Do not point the receiver directly at the rising or setting sun. If installing the receiver where sunlight cannot be avoided, mount it slightly higher than the transmitter and aim it down toward the transmitter. This causes the receiver to look below the horizon.
en | Notices Long-range Beam Smoke Detectors Never mount a detector to a suspended support, such as a pipe or length of wood that is supported at only one end. This type of mounting can create a pendulum effect that greatly multiplies even very small movements at one end of the support. For example, a 2 in. (5.1 cm) movement translates into a beam misalignment of more than 20 ft at 350 ft (6 m at 107 m). Support mounting surfaces at opposite corners to reduce the pendulum effect.

en | Notices Long-range Beam Smoke Detectors The D296 and D297 can be set for quick response (5 sec) or normal response (30 sec). Some burning materials release hazardous gases along with the smoke and should be set for a shorter response times to minimize exposure to the dangerous vapors. Denser smokes, if allowed to collect for too long (obscuration time set too long), can produce near total obscuration of the detector resulting in a trouble signal before an alarm is generated.
