Racal Guardall motion detectors

[CHŽIS]

Looking for a little info on Racal Guardall motion detectors. I have one
from a takeover we did last week, and am wondering how old it is.

It's the "Apollo C" model, batch number 8814, which somewhat resembles this
pic (best one I could find at the moment)...

Any info would be appreciated, despite the fact that this thing is already
half way into a garbage can.

The Apollo C is probably one of the best motion detectors I've ever
worked with. Chubb sold them exclusively to the residential and light
commercial markets (which is how I was introduced to the product) in
Canada. SSI-2000 (a distributor that eventually "merged" with
Burtek/ADI years ago) used to handle them, but they were on the
expensive side (and consequently not very popular).

Do you know how to replace battery for the Apollo C ?

if the PIR is battery powered, from that era, they usually were 3 volt..
If it was like most, the battery would be in a holder tray behind the PC
Board..
On some rare units, they battery might be soldered onto the pcb.
In which case you'd need to do a little solder work,
Be sure an use head sink clips on the legs when doing you soldering..
**( be sure and make note of the polarity, and replace in same fashion..)
It might be more to your advantage to replace the unit completely.
