Chapter 3 APCC Installation Considerations This chapter provides the installation considerations for the APCC. Prior to installing an APCC ensure that the following aspects have been considered in the site design. 1. Identify the devices that will be used with the APCC (refer to Identifying the SPP and Sensors). 2. Determine the configuration of the APCC (refer to Determining the Device Configuration). 3.
Chapter 3 Wireless Sensors Each channel of an APCC interfaces a designated set of sensors to a designated contact closure. Ensure information describing which sensor (or sensors) will actuate a given APCC is available. NOTE: Wireless sensors have a unique identifier known as the Sensor ID. Use this identifier to refer to sensors in design notes and plans.
APCC Installation Considerations Configuration Element Example Data Options 5. Channel Holdover Setting 0 -.75 seconds in .05 second increments 0 6.

Configuration Figure 7.9. Controller Card Channels tab Configuring Channel State Contact closure card channels are independent of one another and are individually configured. Each channel occupies one of the following states: Enabled – the channel is operational; Sensor event data collected by the access point is transmitted to the contact closure card. Disabled – the channel is not operational. (When a channel is disabled, its contact closure relay and status relay are continuously open.
Chapter 7 Configuring Presence Mode Modifier The behavior of a channel operating in presence mode may adjusted by applying one of the following modifiers: Delay – defers the onset of the contact closure by a specified duration. If a vehicle moves off of the sensor before the specified delay expires, the contact does not close. Delay is expressed in seconds from zero to 31. Extension – increases the duration of the contact closure by a specified increment.
