OUTpUTS
Relays
The detector is furnished with fire and fault relays. The

relays are rated 5 amperes at 30 Vdc.

The Fire Alarm relay has redundant terminals and

normally open / normally closed contacts, normally

de-energized operation, and latching or non-latching

operation.

The Fault relay has redundant terminals and normally

open contacts, normally energized operation, and

latching or non-latching operation.

Latching relays can be reset by removing input power

(0.1 second minimum).

An alarm condition will normally over-ride a fault

condition, unless the nature of the fault condition impairs

the ability of the detector to generate or maintain an

alarm output, i.e. loss of operating power.

LED
A tri-color LED on the detector faceplate indicates

normal condition and notifies personnel of fire alarm

or fault conditions. Table 1 indicates the condition of the

LED for each status.

automatic

oi

The X9800 includes the Automatic oi feature — a

calibrated performance test that is automatically

performed once per minute to verify complete detector

operation capabilities. No testing with an external test

lamp is required. The detector automatically performs

the same test that a maintenance person with a test

lamp would perform — once every minute. However, a

successful Automatic oi test does not produce an alarm

condition.

The X9800 signals a fault condition when less than half

of the detection range remains. This is indicated by the

fault relay and is evident by the yellow color of the LED

on the face of the detector. See the “Troubleshooting”

section for further information.

Magnetic

oi / Manual oi

CaUtIon

These tests require disabling of all extinguishing
devices to avoid release resulting from a
successful test.

The detector incorporates both Magnetic oi (Mag oi)

and Manual oi (Man oi) test capabilities. These tests

provide pulses (80 to 100 CPS) to the controller (R7404

or R7494) when the detector is not in fault. If the test

is successful, the controller indicates a fire and the

appropriate zone output is active.

NOTE

If the detector is in a fault condition, a successful
Mag

oi

or Man

oi

test cannot be performed.

The Mag oi test is performed by placing a magnet at the

location marked “MAG OI” on the outside of the detector

(see Figure 2). This action causes the detector to

immediately send pulses to the controller. Controller

response is as follows:

• The Zone LED blinks.
• The digital display indicates which Zone is in alarm.
• The status indicator shows “6” (fire).
