User manual HONEYWELL W7070A2000

[. . . ] It cannot communicate with (but is likewise unaffected by) legacy devices (e. g. the T7270A1001, T7270A1019, T7270B1009, or the RT7070A1008). Power Input power provided must be 24 Vac (±20%), 50 or 60 Hz. The power consumption of the W7070A2000 (including the connected active antenna) is 2 VA. CAUTION Avoid electrical shock or equipment damage. Turn power OFF prior to connecting to or removing connections from any terminals. [. . . ] ZAPP External Antenna, dimensions (mm) Install the ZAPP External Antenna at a suitable location near (i. e. within 30 m) of the W7070A2000.

Relative Humidity 5. . . 95 % non-condensing Receiver Class The ZAPP External Antenna (Receiver Class 2) is an active electronic element. It broadcasts no electromagnetic energy. Communication between the ZAPP External Antenna and the W7070A2000 is via bus (see also Fig. distance The ZAPP External Antenna may be connected to only a single W7070A2000. See also section "ZAPP External Antenna ­ Installation and Wiring" on page 6. Installation of Wireless Systems Due to the use of wireless technology for sending signals from transmitters i. e. ZAPP room units to evaluation units (receivers) and the discontinuation of the use of electrical cable connections, there are some basic guidelines that must be followed during planning and installation. This information is intended to help both the planner with configuring the radio path and the system integrator/engineer or service technician with installation and troubleshooting. 3 EN1B-0396GE51 R0409B W7070A2000 ZAPP WIRELESS RECEIVER Basics for Radio Signals in Buildings Radio signals are electromagnetic waves and as such diminish in strength on their way from the transmitter to the receiver, even when unobstructed. This drop in signal strength is inversely proportional to the square of the distance between the transmitter and the receiver. Table 2. Evaluating installation environment pathway unobstructed direct line of sight gypsum wall/wood brick wall/gas concrete reinforced concrete walls/ceilings typical range 30 m in passages, corridors, up to 100 m in halls 25 m through max. 1 wall/ceiling SIGNAL STRENGTH NOTE: Storage areas and elevator shafts should be regarded as obstructions. ZAPP ANTENNA X DISTANCE ZAPP RM. UNIT ZAPP ANTENNA SHEET METAL Fig. Attenuation of signal strength with distance Physical Obstructions Beside this natural (distance-dependent) drop in signal strength, the presence of physical obstructions (e. g. walls, metallic objects, reinforcements in walls, metallized foils of thermal insulations or metallized heat-absorbent glass) located between the transmitter and the receiver can further weaken signal strength. This is referred to as "damping attenuation. " It is true that radio waves can penetrate walls to an extent, but the resultant drop in signal strength is greater than with unobstructed propagation in the free field. Here are some examples of the blocking effect of different types of walls: Table 1. Blocking effect of different wall materials material wood, gypsum, uncoated glass without metal brick, pressboard reinforced concrete with iron reinforcement metal, aluminum pasting penetration 90. . . 100% 65. . . 95% 10. . . 90% 0. . . 10% ZAPP RM. Obstruction of signal Likewise, avoid mounting the antenna and transmitter such that the radio waves travel along walls (see Fig. 12). ZAPP ANTENNA ZAPP ANTENNA In actual practice, this means that the building material used in a building is of paramount importance for the evaluation of the transmitting range.
