INTRODUCTION

The AP-5 is designed for a broad range of access control applications. Its wireless design and small size make it easily adaptable for a variety of access control requirements. Typically, the AP-5 is used to control one or two door strikes, barrier gates, automatic gates, or door operators.

The AP-5 contains a high-gain superheterodyne UHF receiver which uses an external antenna to pick up signals from up to 500 feet away. Up to 480 Linear MegaCode

transmitters and six Model MGT safety edge transmitters can be programmed into the AP-5’s memory. The AP-5 will retain its memory, even without power.

Three dry contact relays are provided. The ﬁ rst relay (K1) is always for ACCESS. The second relay (K2) can be set for ACCESS or OBSTACLE. The third relay (K3) is always an OBSTACLE relay. An ACCESS relay can be programmed to be either timed or toggled. In timed mode, the relay can each be programmed to activate from 1 to 120 seconds (default 2 seconds). In toggle mode, activating a transmitter will latch the relay, activating the transmitter again will un-latch the relay. An OBSTACLE relay will activate for 2 seconds when a valid signal is received from a Model MGT transmitter. During an obstacle condition, all ACCESS relays will be disabled.

For manual activation, pressing OPEN then the “1” key will activate relay K1. Pressing OPEN then the “2” key will activate relay K2. Each relay will activate for its programmed time only. If relay K2 is programmed as an OBSTACLE relay, it cannot be manually activated.

Relays K1 and K2 can also be activated using the two OPEN REQUEST inputs. Each input (1 or 2) will activate an ACCESS relay (K1 or K2) for its timed amount, or as long as the input is active. OPEN REQUEST inputs override any MGT obstacle activity on relay K3 (but not on K2).

The AP-5 can fully supervise up to six MGT safety edge transmitters stored in six memory locations (1-6). The system monitors each MGT transmitter for hourly status reports, tamper signals, and low battery signals. A beep will sound every 5 seconds if a fault occurs and the trouble source can be displayed by pressing #-1 then 1-6. A transmitter must be activated twice to trigger the ACCESS RELAY if a supervisory trouble condition exists on any MGT transmitter (unless the MGT has been suspended). MGT supervisory conditions can be canceled per individual unit, or globally.

The AP-5 can be powered from 12-24 Volts AC or DC. The three Form C relay outputs can each switch up to 1 Amp @ 24 Volts AC/DC. An EARTH GROUND terminal is provided as a recommended connection for maximum lightning and static protection.

This Linear product is warranted against defects in material and workmanship for twenty-four (24) months. This warranty extends only to wholesale customers who buy direct from Linear or through Linear’s normal distribution channels. Linear does not warrant this product to consumers. Consumers should inquire from their selling dealer as to the nature of the dealer’s warranty, if any. There are no obligations or liabilities on the part of Linear LLC

for consequential damages arising out of or in connection with use or performance of this product or other indirect damages with respect to loss of property, revenue, or proﬁ t, or cost of removal, installation, or reinstallation. All implied warranties, including implied

Linear radio controls provide a reliable communications link and ﬁ ll an important need in portable wireless signalling. However, there are some limitations which must be observed.

• The radios are required to comply with FCC Part 15 and Industry Canada Rules and

Regulations. As such, they have limited transmitter power and therefore limited range.

• A receiver cannot respond to more than one transmitted signal at a time and may be

blocked by radio signals that occur on or near their operating frequencies, regardless of

code settings.

• Changes or modiﬁ cations to the device may void FCC compliance.

• Infrequently used radio links should be tested regularly to protect against undetected

interference or fault.

• A general knowledge of radio and its vagaries should be gained prior to acting as a

wholesale distributor or dealer, and these facts should be communicated to the ultimate

users.
