FAQs: Operation

The WRI has a RS485 interface, can I use it as a wireless modem

No, although the WRI has a RS485 interface, the WRI's current firmware does not support any RS485 communications. (back)
Why do I get 2 red LED flashes after I present a card to a WAPM?

Two red LED flashes about 1 second after presenting a card to a WAPM means that the ACP has denied access or the ACP has taken longer than 1 second to grant access. In other words either that card is not valid at that access point at that time of day or the WAPM's query time must be increased using the CDT. (back)
Why do I get 1 red LED flash after I present a card to a WAPM?

One red LED flash after presenting a card to a WAPM indicates an RF communication error. It means that the WAPM did not communicate to it's WPIM via RF. (back)
How do I know my card has been read?

The WAPM generates a beep when data is received from it's card reader. (back)
Can I set up a WAPM to automatically unlock & lock an access point at certain times of the day?

If the access control panel being used supports timed locks/unlocks, then yes the WAPM will also. The locked/unlocked state of the WAPM mirrors the state of the ACP strike relay. (back)
Can I set up a WAPM to manually allow momentary access from a remote point?

Yes, by using the WAPM's Request to Enter option. If using the Request to Enter option is not desirable and if the WAPM is not battery powered, then setting the WAPM for a fast heartbeat (1-2 seconds) will accomplish the same thing.  Note: A fast heartbeat is not recommended with a battery powered WAPM as the battery life will be drastically reduced! (back)
The door unlocks for a card swipe and stays unlocked, why?

If a WAPM stays unlocked after an access has been granted (i.e. a valid card swipe), it usually means that the ACP is telling the WAPM to go into an extended unlock condition (i.e. the ACP strike relay is always activated). (back)
The door never unlocks, even with a known good card swipe, why?

When a door does not unlock, even with a known good card swipe, check the following: - make certain that the ACP's strike relay is activating when the card is swiped, if it isn't then check the ACP's programming and configuration - make certain that the ACP strike relay's common and normally open contacts are wired to the WPIM strike and ground connections for the correct door. - remove the connector on the WPIM for the door that is not unlocking, temporarily short the strike and ground connections on the WPIM, swipe any card at the WAPM, the door should always unlock - verify that the WAPM is linked to the desired WPIM and to the desired door on the WPIM, use the WPIM LEDs while swiping a card to determine this (refer to the ""Configuring & Operating a wireless Access System” manual for PIM LED indications). (back)
How do I unlock the WAPM’s during an emergency?

Proper and judicious setting of a WAPM's heartbeat frequency will insure that an ACP can unlock a WAPM in an acceptable amount of time. The WPIM can only communicate with the WAPM when the WAPM communicates with it first. The frequency of the heartbeat determines maximum time this latency will be. Any activity at the WAPM (card swipe, request to exit, or change in door position) will also cause the WAPM to unlock. (back)
Does the WAPM make any access control decisions?

The WAPM does not make any access control decisions. The WAPM reports all activity at an access point in real time. The ACP is responsible for all access control decisions, as in a wired system. (back)
What insures that the door won’t unlock with a rogue RF signal?

Several RF signalling schemes are used by the WAPM and WPIM to encode the RF transmissions so that it is virtually impossible for a rogue RF signal to unlock an acces point. The exact scheme used is proprietary and confidential. (back)
What is a heartbeat?

Every WAPM has a heartbeat function. The heartbeat's frequency and resolution is configurable (refer to each WAPM's specifications). The heartbeat function is like a watchdog, a WAPM will communicate with its WPIM at least once every hearbeat period. If a WPIM misses two heartbeats in a row from a WAPM, then the WPIM asserts a "loss of RF communications" trouble signal to the ACP. (back)
How many bits can be read from a card?

A WAS will handle up to 255 bits from a card reader. (back)
What happens when I make a request to exit?

If the WAPM has a request to exit device, everytime the request to exit device changes state (i.e. from not making a request to making a request to exit or from making a request to exit to not making a request to exit) the WAPM reports this change, via RF, to the WPIM which in turn reports this change, via wires, to the ACP. The ACP always knows the real time state of the request to exit device. (back)
What happens when I open a door?

If the WAPM has a door position switch, everytime an access point's portal changes state (i.e. from closed to open or from open to closed) the WAPM reports this change, via RF, to the WPIM which in turn reports this change, via wires, to the ACP. The ACP always knows the real time position of the portal. If the WAPM does not have a door position switch, then the ACP does not know the current position of the door. (back)
What happens when I swipe a card?

When a card is swiped or presented at a WAPM, the WAPM receives the data from the card reader. If the WAPM is configured to do a card code conversion, it does it now. The WAPM then transmits this card data to the WPIM using RF. The WPIM receives the data via RF and tells the WAPM that it received it. The WPIM then sends the card code data to the ACP via a wired connection. The WAPM continues to re-query (i.e. sends another message to the PIM), via RF, the WPIM to see if it is supposed to unlock the door. Tha WAPM re-queries for about one second. If the ACP strike relay activates, then the WPIM tells the WAPM, via RF, to unlock the door the next time the WAPM queries. If the ACP strike relay never activates and the WAPM has exhausted it's requeries (about 1 second), then the WAPM gives an "access denied" indication. (back)
