Section 9: RELAY OUTPUTS
Relays, used in conjunction with this control panel, are programmable switches
that can be used to perform many different functions. They can be used to turn
lights on and off, control sounders, or for status indications. In this system, each
device must be programmed as to how to act (ACTION), when to activate
(START), and when to deactivate (STOP). Each of these is described later in this
section.
This control supports up to 4 4204 or 8 4204CF Relay Modules. Each 4204
module provides 4 relays with Form C (normally open and normally closed)
contacts. This means you can program up to 16 relays to activate and de-
activate as desired.
supervised bell outputs to the system. If 4204CF modules are used exclusively,
only relays 1 and 3 on each module can be programmed. The other 2 relays
(relays 2 and 4) on each module are used for supervision purposes.
This section is used to program relays to activate in response to a programmed
condition. The system can also be programmed to activate relays at specific
times by using the #80 Scheduling Menu Mode–Time Driven Events function.
1. Set the 4204 or 4204CF's DIP switches for a device address between 01-15
that is not being used by another device (keypads, RF receivers, etc.).
The relay module will not operate until the device address you have chosen is
enabled in the control's Device Programming mode.
2. Mount the 4204 and 4204CF modules as per the instructions provided with
these modules. Connect the 4204/4204CF module(s) to the control's Keypad
1 terminals (11-14) when mounted remotely from the control (they may be
wired to Port 2 when mounted on or within the control's cabinet). Use the
flying lead cable or the screw terminals provided with each relay module to
make connections.
3. When mounted remotely, home run each module back to the control. The
table below shows the maximum wire run lengths from the control to each
4204. Refer to the instructions provided with the 4204CF for its maximum
permissable wire lengths.
