Page 10: Pre-Installation
Pre-Installation This section provides the following pre-installation information: • Location considerations • Height requirements • Mounting surfaces • Address settings Location Considerations Placement of the sensor and the receiver is critical to proper operation. For most installations, barriers limit proper radio signal strength more than distance. For best radio transmission range and reliability, mount the receiver and sensor in line of sight. -
Page 11: Height Requirements
Pre-Installation • High traffic areas (to reduce accidental damage or tampering) • Metal barriers between the receiver and the sensor (for example, plastered walls with metal lathe or metal roof decks) • Thick, solid concrete walls between the receiver and the sensor •... - Page 12 Pre-Installation To set the receiver and sensor addresses: 1. Using a small screwdriver, set the three rotary address switches (locations S1, S2, S3) on the receiver to an address between 001 and 999 (see Figure 1). (You do not have to remove the covers to access the rotary address switches.) Note: Do not use 000 as an address.
