Solution 1149403.1 : SL8500 - SL8500 Smoke Detector Maintenance

Applies to:

Sun StorageTek SL8500 Modular Library System - Version Not Applicable and later
Information in this document applies to any platform.

SL8500 Photoelectric Smoke Detector
SLR-24V
PN_410273303

Note – Replacement of the smoke detector is no longer an annual preventive maintenance (PM) requirement. There is, however, a requirement for periodically checking its correct operation. These procedures are provided in the SL8500 Service Manual.

Purpose

Instructions to test the Smoke Alarm / Detector in the SL8500 library.

Troubleshooting Steps

Smoke Detection:
The air flow pattern is designed to draw air from the front of the library through the cartridge drive area, assuring that smoke in any part of the library will be accurately detected. In the event that a fire has produced excessive and dangerous smoke within the library, photoelectric smoke detectors (mounted in rear, upper right of the electronics and drive module) activate and all power shuts down.

(Taken from SL8500 Install Manual)

Test Procedure:
Below are the instructions on how to test the detector without “canned smoke”. But it is highly recommended that the smoke detector be tested with canned smoke if possible. Testing the smoke detector by shorting pins on the connector is not recommended as shorting the incorrect pins will blow the 24V fuses in the PDUs that supply power to the Smoke Detector circuit and the smoke detector itself is not tested in this manner. Vary the library and related drives offline. This procedure will remove all power to the library and drives.

Testing Smoke Detector Shutdown Circuit
Testing is accomplished by removing the smoke detector connector J857 and shorting together pins 1 and 2. This will trip the AC breakers and remove all of the AC power to the library.

During onsite visits monitor the status of the 2 LEDs on the smoke detector:
1. Under normal conditions, both LED's flash green.
2. When the sensitivity drifts outside of its sensitivity limits, both LED's flash red.
3. In the alarm state both LED's are red continuously.
4. When the sensitivity drifts outside of its sensitivity limits and both LED's flash red, the smoke detector should be replaced.
