Boards for HiPath 3000

STRB, STRBR

Introduction

This option comes in two versions:

STRB (Control Relay Board) S30817-Q932-A (Figure 3-160) - for use in HiPath 3550 and

HiPath 3350 (wall housing)

STRBR (Control Relay Board Rack) S30817-K932-Z (Figure 3-161) - for use in HiPath

3500 and HiPath 3300 (19-inch housing)

The STRB or STRBR has four double-pin, double-throw relays as shown in Figure 3-162).

Actuators and sensors for monitoring, alerting, controlling and regulating can be connected to

the control relay board. Actuators are relays that can be energized from any station by means

of a code (such as a door opener). Sensors (such as thermostats or motion detectors) can de-

tect a change of status in the connected equipment and activate a feature or dial a station num-

ber stored in the system.

The board has a total of four outputs (in the form of two floating switch contacts each) and four

control inputs in the form of optocouplers for externally activating an electrically isolated nor-

mally open (NO) contact.

CDB data is stored on the board. When replacing the board, be sure to store the

CDB data elsewhere. If a used board is used, old data may still be present on the

Only factory technicians should use the "Reset options" procedure in expert mode

(code 29-3-3). Using the procedure during operation returns all options to their fac-

tory defaults, and they must be reset before they can accept data again from the cen-

Example: You can route the +12-V signal for power failure alert to the control input of the opto-

coupler for connector X4 or X6. Route the signal through a normally open (NO) contact that is

electrically isolated from the external device, then program the alert type. For safety, the control

voltage for the optocoupler is electrically isolated from the system's other partial voltages.

For the manual relay on/off function and door opener, you must enter the desired switching time

(expert mode code 26 2).
