INSTALLATION

5-44

System 2 Installation / Programming Manual

You must ensure that the RTE wire from Terminal #27 Never can be accessed by

unauthorized personnel at any location where the Keypad or Card Reader Wires are

available. During Installation, breakout Terminal #27 wire prior to the Keypad or Reader

site and run it direct to the RTE switch. If the Terminal #27 wire is shorted to Terminal #22,

the door will Open!

Request-To-Exit Button (RTE) / Passive Infrared

With the addition of a Normally Open “button” or Passive Infrared device, the door relays can be activated to

release the door locks. The RTE must have a set of normally open contacts that close a circuit when

activated. It is also recommended to break power to the electromagnetic door lock (Mag-Lock) with a

separate set of contacts in the RTE switch. These extra contacts must be a normally closed circuit that breaks

power to the Mag-Lock when activated.

The Request-To-Exit (RTE) function is used to allow emergency exit from a locked area without having to use

the Keypad or Reader. This function can also be activated from a remote guard location to open or close

doors on command. The System supports up to two "normally open" RTE switches. When the main relays are

set for latching, the RTE switch will activate the relay (toggle) each time the switch is used.

RTE Wiring

The RTE or Passive Infrared can be located up to 500 ft. from the System 2.

RTE Ground

Request-To-Exit (RTE) buttons do not need to be grounded at the RTE location. The shield of the cable

running to the RTE should be connected to Terminal #1 of the System 2, which must be an earth ground.

RTE, Lamp & LED Connections

RTE’s may be located up to 500 ft. from the System. Generally they are wired using the same cable that is

used for the Card Reader. RTE p/n 4035 contains a “Bayonet Base” LED lamp to illuminate the button. This

LED amp draws very little current and far outlasts an incandescent bulb. Polarity must be observed when

connecting to this LED. CAUTION!!! The LED must not be replaced with an incandescent “Bayonet

Base” bulb when used with the System 2 because it will draw too much current and exceed the

maximum allowed by the System. (Refer to Figures 14 - 24).

Fail Safe Operation for RTE

RTE p/n 4035 and 4135 have two sets of contacts. The open set of RTE contacts is used to trigger the RTE

input on the System which will unlock the door for the programmed relay time. The closed set of RTE

contacts should be used to break the power to the magnetic lock. This provides an extra margin of safety to

exit if the System is taken down or goes off-line for any reason.
